Updated 8386 Ferrari F1 Racer


On December 18th, 2004 I bought 8386 here in Cologne, Germany. It was the first LEGO set I bought in 7 years, and thus was the end of my Dark Ages. It was my return to LEGO. Today marks ten years since I bought this set. This is a celebration of that event 10 years ago.

Updated 8386 F2004

A lot has happened in the last ten years. When I think about that time I pause to reflect on where I have come. I have lived in 10 different places, including three states, had a number of different jobs, and increased my family unit by a factor of three. But people don’t come to this website to read about me, they come for LEGO. Over the last ten years we have gained much. The Technic line has improved both in terms of functional abilities, but also in the frequency and quantity of models offered. We have gained Power Functions. We have Linear Actuators, CV joints, more suspension parts, and so many more wheel options. We have favorite elements that did not exist ten years ago. Colors now include green, blue, white, and orange. LEGO made a Unimog. Bricklink started not much more than 10 years ago. Let that sink in for a moment. All of these developments have made so much of my building possible. It only makes sense to celebrate with a MOD of the set that reminds me of my return.

8386 was a rather basic set. It was modeled after the F2004 car #1 or #2 of the 2004 Scuderia Ferrari team through a licensing agreement with Ferrari. The cars were rather successful during the 2004 season at the hands Michael Schumacher and Rubens Barrichello. 8386 included working steering, a working V-10, and a removable engine cover. And that’s about it. Oh, and a lot of stickers. As I did with the 8081 4×4 my goal was to keep what was there, and improve what I could. I would add some additional features, namely suspension and a gearbox. Since 2004, LEGO has added a number of elements that made these goals easier than they would have been ten years ago.
First, I built 8386 as is. After a good hour, I had the stock 8386 complete. I had my constraints, so now I needed to modify the set. I started with the front suspension, as I thought that would be rather difficult. Turns out it wasn’t. I removed a couple of axles, and added in two hard shock absorbers. The geometry made the suspension adequate. It could have been a little harder, and could have been a little more aesthetically pleasing, but it worked.
8386 Front Suspension
On to the rear. First to go was the trans-clear engine. Ugh. I knew I wanted to add rear suspension, but I was not sure I wanted to add a gearbox due to the limited space. I played around with some designs, and decided I should give it a go. I came up with a design that would need only 7 studs of space. The design would be off center of the car, which would present some changeover problems, but saved 3 studs of length. One axle would connect directly to the new style differential, and the other axle would connect directly to the crankshaft of the V-10. At first, I set the gearbox behind the differential, but I found that option to be rather unsightly and added some complications to the gearshift linkages. With some modifications to the chassis, moving the V-10 forward a stud, and increasing wheelbase by moving the rear axle back 1/2 stud the gearbox would fit.
8386 Gearbox
Once the gearbox was designed, I worked on the rear suspension. The gearbox got in way of the suspension design I wanted, but that was a cost I was willing to pay. I used the same upper arms as 8386, but created a liftarm design for the lower arm. Two shock absorbers connected from the chassis to the slightly modified wheel hub. While a pushrod design would have been nice, this setup worked well enough for me. I added a simple linkage to the gearbox that connected to levers in the cockpit. It looks a little clunky, but it allow all the controls to be at hand. I then made some modifications to the exhaust system so it would fit the added features. I made some modifications to the body work to give the car some visual lines that matched F2004, and added a little more white. The car was done.
End of the V-10, beginning of the cramped transaxle.

End of the V-10, beginning of the cramped transaxle.

All in all the design worked well, and required less time than some of my more fancy builds. It was a restful project, and one to which I enjoyed returning.
Maybe in another ten years, I’ll update this again with new features made possible with 10 years of LEGO changes and developments. I look forward to it.
Happy Building.

Kenworth T47


The Kenworth T55 is my favorite Trial Truck I have built. It’s not the best looking, or the most capable, or the most reliable, or even the most popular but it’s the one I keep coming back to. My latest truck is a continuation of the Kenworth series of trial trucks. The T55 would pull a stump, the T47 is quicker, has better steering, and more compliant suspension.

T47

Right from the beginning I knew the truck would have a similar cabin at the T55. It would continue with the four wheel steering, and I added an independent suspension. The dimensions would stay close to the same. From there anything else was fair game. I started with the axles. The new suspensions arms made it a little bit easier to make a good independent design. A CV joint was used at the steering knuckle, which allowed for the steering pivot to be near the wheel. Each wheel had about three studs of travel.

The XL motor was placed on the left of the center line and the rechargeable battery box was placed on the right. A newly acquired Servo Motor was placed rear on the centerline directly in front of the rear axle. I had a little more space left, so I added a simple two speed gearbox. A little more space remained so I added a flat six engine.

T47 Engine

Part of my attraction of the T55 has been it’s coloring, and it’s shape. I wanted to keep the attraction similar, but in a way that would differentiate the trucks. I have been acquiring some green lately, so I thought would be a great color. The cab is basically the same, but now it can tilt so you can work on the engine.

The off road performance was not great on the T55, and the T47 was similar. The independent suspension had too much play at the wheels to be great at steering, and the articulation was not very supple. The truck was great to drive around my house, but when I took it outside it did poorly. The suspension design is better than my last independent set up. There was no slipping of the gears. I think my next design will use the same knuckle, but design a different steering connection. This truck again proves the use of knob wheels rather than a differential for a trial truck. Feel free to make your own, and let me know what improvements you developed.

Happy Building.

Octan F1


In a bought of inspiration (or distraction) at work, I noted my old 6546 sitting on my desk. After years of looking at this small car I thought, I could make this bigger, and in Technic. Done.

The full gallery including instructions can be found here.

Octan F1 Front

I decided the car should have a simple engine, four wheel suspension, and working steering. Recently, there was a good design that gave me an idea about how to do a smaller scale driveline for the car. I worked on the rear first, and once I had the suspension setup, I added a small flat four engine place directly on the bottom of the car. This would be the basis for the rear of the chassis.

I then started the front suspension design which would utilize the new suspension components from 42021. I first tried adding shock absorbers. Then I added rubber connectors. The first was too big, the second did not work to well. After monkeying with it for a while, I developed a simple torsion bar setup. The torsion axle is a 10l and provides the pivot point to the bottom control arms. They connect to the chassis behind the suspension to a fixed point under the steering wheel. The set up works well. Frankly, it works a little better than the rear as the rear could benefit from stiffer arms and suspension mounts.

Next came the body work. As I wanted to keep things similar to the 6546, the coloring would have to be white, green, and red. And it would need some stickers. I used the stickers from set 60025, so the car number would have to be changed from the original #4 to #5. The coloring and markings turned out well. I tried to make sure it was not too busy. Easy enough, and everything is easily acquired so you may build your own.

Fitting with my yearly planning I have now completed the two small builds I wanted to complete. It was quick, fun, and a MOC that is accessible for other builders. Feel free to build your own (make some new colors, and we can then have a race).

Happy Building.

Hawker Typhoon MkIb


Two years ago I built the Spitfire MkIIa. It remains one of my more popular builds, and one of which I am still quite proud. It was not my first large plane, though when I completed it, I said it would be my last.

As my father would say, “never say never.”

Typhoon

The full gallery may be seen here.

I learned a lot of great things from the Spitfire. Large scale building is exciting, and challenging in that you have to think about significant structural considerations, placement, and shaping before and while your build.

With this in mind, I wanted to develop what I have learned, but allow myself the ability to take a large scale aircraft to the next level. I wanted to improve the function of the control surfaces, design my own propellor, use four Power Function channels, and use the boatload of Dark Green parts that I had recently acquired. I considered a number of airplanes, including doing the FW-190 again, but I finally settled on the Typhoon. Time to get building.

After some planning, I had my scale. 1/13 was an appropriate size for me to replicate the plane and its functions, while still keeping the plane from getting too large. This scale would also allow for LEGO wheels for the landing gear, and a worker able propellor spinner design. As I learned from the Spitfire, placement of large components needed to be done early, and placed in the MOC to its exact final location. As the structure of the fuselage and wings would be stressed heavily, large components could not get in the way. Once I placed the engine block, the landing gear, the power functions, and the control surfaces, I was able to start putting together the robust structures that would support the final plane. One of the major challenges of this plane was the outset landing gear on the wings. Because they were located 42 studs apart, the wings needed to be strong. But due the the space taken for the control surfaces, and the massive 24 cylinder power pack, the wings still sag a little under load.

The control surfaces were activated with strings with studs on each end. I found this to be a better system than the axle controls for the Spitfire. It kept the controls more smooth, and reduced the amount of play in the controls. The elevator and ailerons were controlled with the joystick, and the rudder was controlled by two foot pedals in the cockpit. The remaining functions were controlled via Power Functions. An XL motor powered the massive 38 stud diameter propellor, as well at the 24 cylinder Napier Sabre engine. A M motor controlled the pitch of the propellor. Another M motor powered the landing gear, and still another  adjusted the flaps. All four motor were mounted in the chin of the aircraft; I had to use that huge chin for something. The two IR receivers were mounted in under the windscreen, and the rechargeable battery was mounted behind the cockpit.

Finally, I had to make sure all the markings were accurate. Again, due the limits of dark green parts, it was not an easy task. I started with wings, and made sure to add invasion stripes, and work my way out to the tips. The roundels were a little different than the Spitfire, but were a little larger. The fuselage took a little work to make sure the panels could be easily removed, but I eventually got there. The fuselage roundel should have a yellow ring around the outside, but the strip is so small, I could not figure out a good way to do it.

The plane worked almost perfectly. The ailerons were a little sticky, but other wise everything else managed to work for an 8 hour shift at Brickworld. The plane was liked enough to be nominated for Best Air Ship. While it did not win, it was validation that the the model was a success.

Happy Building.

JCB 714


My repertoire has become quite diverse over the years. I have made large cars, large planes, MODs, and many other types of builds. I enjoy those builds, and I get an immense amount of satisfaction completed them. Recently I have enjoyed making smaller, non-powered, Technic MOCs. I can generate more small build ideas, I can stay motivated better, and I enjoy the playing with final result more. So I made another small MOC, the JCB 714.

The full gallery may be found here. Instructions may be purchased for $5 USD.

JCB 714

This MOC started when I was browsing the JCB UK website. I thought the 714 would be a fun little project that would have some nice features, and would utilize some of my collection that is not currently being used. I started working on the frame. The MOC would have a four wheel drive system, suspension, steering, and a dumping back. I designed two suspension/steering designs, and while the first one was awesome, it was not as stable as I would have preferred. So I reverted back to the design utilized on the real JCB. It was not as flashy, but it worked well. A turntable is planted behind the steering pivot, with the drive axle moving through the center of both. A liftarm was placed on the left to operate the steering function. The drive axle would connect to both axles through a 12/20 gear reduction which connected them to two differentials. The I3 motor was placed in front of the forward axle.

The rear was more challenging than I expected. First, I had to plant the mLA’s in such a way that they could be connected by a single axle that would not impede the driveline. Second, the mLA’s had to operate in such a way that the bucket could do the full range of motion; nearly 90 degrees. Third, the shape of the bucket did not work well in LEGO, as there were limited flat surfaces. Thankfully the sides were flat, and some of the bottom. The bottom was connect to the dump pivot, and the sides would hold the angled panels. Finally, it had to make sure the rear wheels could still move freely. While there are still some holes in the dump, it works well enough to transport a bunch of bricks.

The cab built up fairly quickly, and allowed me some space to add the rear window grate, and a exhaust pipe. The hood can open, and there are steps to get into the cabin. Safe egress is important.

As I am finding with MOCs that do not utilize Power Functions, the MOC functioned well, every time. No maintenance is needed, gears do not skip, and the MOC works as it is designed. This is part of the reason I am building these kind of MOCs more often. The MOC worked as it was designed, just like a MOC should.

Thanks for reading and happy building.

 

 

8081 RT


I have said it before; I really like set 8081. It has so many possibilities for improvement. After talking a look at RM8‘s design, I thought I should do a street version of the 8081 to follow up on the 4×4 8081 I built a while back.

The full gallery can be found here, and free instructions can be found here.

8081 RT Front

I took the existing bodywork and frame of the 8081, and chopped out the rear suspension unit to revise the rear suspension design. I wanted an independent setup with a differential. As I have used a couple of times before, I used a floating differential design. The differential is attached to the driveline much like a live-axle set up, but is connected to two independently mounted wheel hubs. I have used this before, and I like the way it works. It allows for a driven axle with independent suspension in a very narrow setup. This way each wheel can move independently, but it does not require two universal joints on each side of the differential. Since the differential is not fixed to the chassis, it has to be braced to the driveshaft. While this set-up is not often used in real cars, it works well for LEGO designs. I used the new wheel hubs, and attached them via a short upper arm, and a long lower arm so the camber would change through the suspension travel.

Moving to the front, I kept the V-8 as in my 4×4 8081, and built the rest of the front around the motor. I used a suspension design similar to 8081, where there are two equal length arms holding the steering pivot. A single shock absorber is used for each side. All told, the car is about two studs lower, due to the new suspension, and the new tires.

It is not much of a redesign, but sometimes I need a project that is not a significant, and allows me to just build something simple.

Happy Building.

The Sod Farm


During two summers when I was in college, I worked on a Sod Farm. It was, let’s say, a developmental experience. The days were hot, long, and often included nothing more than sitting on a tractor listening to the diesel drone as I would slowly mow the sod at 1.8 mph (2.9 kph).

While I would often  recite the dialogue of Sgt. Bilko in my head to pass the time, I did manage to develop a deep fascination for the machinery used. Two months ago, Eurobricks decided to hold a contest to create three Technic creations that would work together. After some thought about the rules, the parts I had, I thought I could create an entry, and offer something a little unique.

The full gallery may be found here, and instructions here.

The Sod Farm

The contest required three models that would work together in a particular setting. Each must have a part count that did not exceed 500 parts, and each had to be unique. While trailers were acceptable, I somehow felt offering an entry with a trailer did not allow for enough creativity. As my thoughts wondered on a bike ride, I decided I would create a small truck, a little forklift, and a sod harvester. My design would harken back to those days on the sod farm. Rather than the Freightliner Columbia and Piggyback Forklift we used, I designed a MAN TGS and a JCB 150T to have little more international flair, and frankly, to have a little more color. We used a Brouwer SH 1576 to harvest the sod, so I thought I should keep that machine.

The MAN TGS went through a number of revisions. Each was done to reach the part limit. The final MOC ended with a three function knuckleboom crane and a simple bed. In addition to the steering and the working doors, the crane is fully functional. The rotation is handled by a wheel on the right of the truck, and the main lift is handled by a wheel in the rear of the truck. The second stage lift and boom extension is handled by a small wheel at the top of the crane.

The JCB 150T was a simple and straightforward build. Recreating a MOC with a single arm lift created some additional challenges. A single mini linear actuator was used to lift the boom, and a worm gear system was used to adjust the tilt of the forks. The offset cabin caused some frustration, but I eventually figured it out.

Finally, the Brouwer SH 1576 was the purpose of this project. After a little research, I determined the scale of the project. I then started building. I usually add too many features to a MOC, and this harvester was no exception. The rear wheels spun a single differential, which ran straight to the front to power a two cylinder motor. Off the driveline was a PTO between the motor and the differential which would run the harvesting arm. The harvesting arm has a track system to drive the pieces of sod up to the back of the harvester to load the sod on the pallets. A simple cutting head was added to the front which had a cutter to cut the sod off the ground, and a timed cutter on the top to make sure each piece of sod was the correct size. After some work I added a simple steering system controlled by the smoke stack. Finally, I added a forklift system to hold and drop the pallets of sod off the back, and a small standing pad for the pallet worker.

This was the first LEGO contest I have entered since 1994. I hope you enjoy my entry. Thanks to Eurobricks.com for the contest. I appreciate your vote at eurobricks.com. In addition, instructions for the models can be found here.

For those counting (me), the number of parts needed for each MOC are: MAN TGS- 557, JCB 150T- 287 (inc 58 tracks), Brouwer 1576- 484 (inc 43 tracks)

Spitfire Mk IIa


I am not a very ambitious person.  Sure I made it through college and graduate school, and have managed to work well in job for a while now, but for me to do something challenging, takes a lot of convincing.  It doesn’t happen often.  This project was a little bigger than it should have been, and I got in over my head.  This is not the first time this has happened (1, 2).  The project was interesting enough for me to keep moving forward, even after six months.  I present my 1:12 scale Spitfire Mk IIa.  I hope you enjoy the work.

View the full gallery here, and the work in progress gallery here.  Flickr set is here.

Spitfire 3/4

First, the whole reason I did this project was because of the excellent Baby Twin Otter of Cpt. Postma completed two years ago.  If you have not yet seen this creation, take a look at the above link.  When I first saw this model, I went home a made his variable pitch propeller   This was the first step to my Spitfire, though at the time I did not know it.

I chose to do the Mk IIa version Spitfire for a couple of reasons.  First, the model had to have a three blade prop, because I wanted to use Cpt. Postma’s design.  Spitfires stopped using a three blade prop somewhere in the middle of the MkV series.  Second, I wanted to model a eight gun variant, rather than the cannon variant because I think it has a cleaner look, and I love the red and yellow leading edges on the eight gun variants.  Finally, while it would have been great to do a early model Spitfire with the dark tan camouflage  adding both the dark green and dark tan would have been too expensive, and even more ambitious.  I found a number of pictures of a certain MkIIa with all the features I wanted.  I chose a Spitfire flown by Lt. Tomas Vybiral, who was a Czech pilot with the French Air Force.  The plane was Spitfire P8081 when he flew for the British in Squadron No. 312.  It had simple markings for me to recreate, a camouflage pattern I would be able to do (read afford), and I found some good documents to help my modeling.

Next came the internal planning.  The Spitfire would have working ailerons  flaps, rudder, and elevators (with correlating pilot controls), prop, prop pitch, V-12 engine, and retracting landing gear, all within the 1:12 scale.  Once I had the dimensions calculated, I started placing things in a simple “placeholder” model on my floor.  I constructed the engine, the propeller spinner, pedal/joystick assembly and placed them in the placeholder.  Then I made the placeholder 3D.

It took two months to get the rest of the internals all set.  The required moving various parts of the 3D placeholder, and adding additional parts.  The joystick is connected through various liftarms to the rear elevator, and by axles to the ailerons   The pedals connected though a shaft to the rear rudder.  You can see the gears on the rudder.  The flaps have a simple lever in bottom left side of the cockpit.

The rest of the functions are controlled via Power Functions.  The small 8878 battery box is placed behind the cockpit, as is the IR receiver.  A PF M is housed under the V-12 and drives four mini linear actuators for the landing gear.  It is strong and simple, and works well.  It does not have the correct Spitfire landing gear geometry, but if someone can figure out a way to do it at this scale…well, I can’t figure it out.  A second PF M is used to power the propeller   It is placed directly behind the V-12.  Finally, a third PF M is placed behind the V-12, and works through a system of gears to power two mini linear actuators to move the pitch of the prop.  It’s messy inside, but it has everything I wanted.

After the internals, I had no idea how hard the rest of the Spitfire would be.  LEGO, you need to make more parts in Dark Green.  I know how selfish that sounds, but it would have been more helpful.  Thank to some newer sets, like the 10226 Sopwith Camel, and the  21016 Sungnyemun, it made it much more possible, but still limited me in many places.  I spent the next four months acquiring parts, and placing small plates over the rest of the plane.  With some help on the roundels from Dieterr89, it eventually came together.   The bodywork took a long time.  Too long.  And the lack of some parts in Dark Green forced me to make some concessions.  The canopy frame should be all Dark Green, but it was not going to happen with what is available.  The camouflage is not as clean as I would have liked, and there are some abrupt steps where some plate limitations made the transition for one part to another not smooth enough, such as on the rear fuselage.  Also, try as I might, I could not get the leading edge of the wing to be perfect.  The dihedral did not help either, nor did the yellow leading edge.  Also, the gaps between the control surfaces and the fixed part of the wing and stabilizer was more than I would have liked.  But this has happened before.

I am please with how it turned out, but there are some parts that I wish would be better.  I never seem to remember this when I start a project in this scale, but free moving functions just do not operate well as you hope when you keep adding parts.  The control surfaces work, but they could be smoother and lighter.  The powered functions worked flawlessly. I was very please with the way the markings turned out.  They are not as flush with the plane as painting would cause you to believe, but they make the Spitfire clearly identifiable.

My father would always tell me “never say never,” but it may be a long time before I do another large plane.  But I guess I said that back in 2008.

I hope you enjoy.  Thanks for reading.

Mack Marble 5T


I confess.  I took the bait, and started on the 2012 You Design It, We Build It before the final rules had been confirmed.  I should know better.  After all my schooling, you would think I have a good idea about how to follow directions.  The first direction is, wait for directions.  But, with all LEGO building, I enjoy what I am creating, and so even after the rules and directions have been given, I still want to contribute to the LEGO community.  So, my next MOC is another Trial Truck, built with the intention of being easy to play with, easy to build, and tough enough to handle child play.  All with instructions, so you can build one.

See Instruction Page

I built this model based on what I thought could be improved on set 9398.  While this new set was a great step forward for the LEGO company, I felt there where a couple of changes that should be made to make the model a better off-roader.  Because I was working with the assumption that this would be something LEGO would produce, I gave myself a couple of constraints.  First, the model had to be less than, or equal to, the cost of 9398.  Second, the model had to have improved off-roading skills.  Third, the model had to have easy playablity, so the drivetrain had to be reliable, the battery should be easy removable, and it should be easy to drive.

I started the frame before the axles.  I placed the battery box directly over the driveshaft.  An XL motor was place behind the BB and three 16z gears above the driveshaft.  One 16z gear went up to the fake motor shaft.  The driveshaft would connect front and rear to the two axles through the new ball joints from 8110.

I then built the two axles, starting with the rear.  To keep the speed of the Mack similar to the 9398, I would gear down the XL motor to about 1:4.  The driveshaft came out of the ball joints and connected to the differential.  I chose two 12z/20z gear sets as the final reduction.  This would keep the driveline a little stronger, and help keep various axles from working their way out of the gears, much like the design of the 9398.  The final gearing was 1:3.89.  It’s not a stump puller, but it could still move up most hills.

The front axle was a little more tricky.  Basically, it had a similar setup, with a PF M motor placed on in it to work the steering.  This was by design.  To keep the driveline reliable, and limit the failure of steering, I kept the steering part of the axle, rather then having components placed in the chassis, and then connected via a shaft to the front axle.  The steering is a little quick for my liking, but it works flawlessly.  To understand more about the axles, check out the instructions.

Through a little trial and error, I connected the suspension, and tweaked it so it would function in a way that was robust, and allow for great movement.  I am still not pleased with how it turned out aesthetically  but it functioned without problems, it supported the model well, and allowed for sufficient articulation, so I left it.

I then added a simple body, a basic rear bed, and added some engine components such as exhaust,  intake, and a simple turbocharger behind the fake motor.  When I was done, I noticed the cab looked a little like an old Unimog.  This seems to be a theme with me, as I love the look of the Unimog.  On the other hand, I do not like the look of too many cabover truck designs, as such, many of my trucks have the slight setback cabover design that is very similar to the Unimog.  My T55 is like this, and this is why I have built so many Unimogs.

The model worked well.  the suspension and stability was perfect.  The truck was stable, and did not roll over, all while being able to handle various terrains.  The gearing was sufficient and would be great for a playing child.  It was easy to change out the 12z/20z gears in the portal axles to a 8z/24z setup which made the truck a little more strong.

It would be a great model for many LEGO fans due to cost, reliability  stability, and playability.  So I have posted instructions for people to enjoy the model as well.  I think it would have been a great LEGO set, then the rules were released.

Next time I’ll wait for the rules.  Thanks for reading.
