Tommy Styrvoky Posted March 28, 2016 Posted March 28, 2016 I have always wanted to build a 8x8 or 6x6, I recently acquired 10 62.4x20 tires, so now I can get to building a multi-axle vehicle. I also purchased a Sbrick, this will allow me to control my models at a greater distance outside. So I wanted my first model with a Sbrick to be special. The M8 Greyhound is a light armored car, that is mainly for scouting roles and mounts a 37 mm gun for supporting fire. When designing the drivetrain, I wanted a functional suspension system, and differentials. I attempted to replicate the real setup with staggered differentials, but this failed as there wasn't enough space, so I was forced to use a similar axle setup of the Arocs, as this is rather compact, but because of the height of lego springs, this made it very difficult to mound more than one L motor. I initially wanted this to be powered by two L motors, with a 1:1 ratio between the driveshaft and the differentials. Because of the height of the suspension, the roof of the engine deck will be very close to the top of where the shock absorbers are mounted. This has created a very interesting challenge, The low profile of the vehicle severely limits the area where I can mount power function elements. My progress over my short easter break is shown in the images below, I won't be able to continue progress on this model until the end of April, as that is when college is finished.

BusterHaus Posted March 28, 2016 Posted March 28, 2016 Good start! Are you planning more projects for the summer? Quote
Tommy Styrvoky Posted March 29, 2016 Author Posted March 29, 2016 (edited) Good start! Are you planning more projects for the summer? Yeah, I list all of my curret projects on my blog, I plan to build all of them up to the Churchill AVRE SLB for summer. http://tommystyrvoky...ure-models.html Edited March 29, 2016 by Tommy Styrvoky Quote
BusterHaus Posted March 29, 2016 Posted March 29, 2016 Awesome, can't wait to see the Churchill and AT-TE. Quote
grum64 Posted March 29, 2016 Posted March 29, 2016 That's some list of projects. I very much look forward to seeing the Churchill, M1070 HET and the People Eaters Limo. Quote
2LegoOrNot2Lego... Posted March 29, 2016 Posted March 29, 2016 Excellent work on squeezing it all in there, keep it up!!! Quote
Tommy Styrvoky Posted March 29, 2016 Author Posted March 29, 2016 Wow this is compact! Keep updating. I can maybe model some of the parts in a digital program, so I can fix the issues it currently has. Quote

I'm not sure yet with the People eater's limo, I know I could build the 6x6 and the limo, but I lack the wheels for the trailers, I think I may use a single 56x26 balloon tires to replace the doubled tires on the actual trailers, and make the trailers all wheel drive too.

Technic Jim Posted March 29, 2016 Posted March 29, 2016 Did the 10 wheels happen to come attached to a big yellow crane-like model?! Quote
Tommy Styrvoky Posted March 29, 2016 Author Posted March 29, 2016 Did the 10 wheels happen to come attached to a big yellow crane-like model?! No, I bought them off of bricklink. Quote
Technic Jim Posted March 29, 2016 Posted March 29, 2016 No, I bought them off of bricklink. Ok! Quote
LucyCol Posted March 29, 2016 Posted March 29, 2016 Looking forward to the Churchill AVRE SLB, as many years ago (40) I drove one for a demonstration. Quote
Kelkschiz Posted March 29, 2016 Posted March 29, 2016 Looks like you are off to a good start. Nice compact chassis. Looking forward to the IS-7. Don't recall seeing an IS-7 in LEGO. Will be an challenging shape to build i fancy. Quote

Don't recall seeing an IS-7 in LEGO. Will be an challenging shape to build i fancy. I think for the IS-7, I will use a combination of flexible axles, and technic bricks to create the semi-round structure of the front and rear of the turret. Looking forward to the Churchill AVRE SLB, as many years ago (40) I drove one for a demonstration. Cool, you're lucky to have the chance to drive one. I think I may decide to convert that model into the AVLB variant too, I love the complexity of the Allie's bridgelayers. I attempted to build one a long time ago, when I built a churchill, but I didn't have enough power from the m motors to actuate the arm for the bridgelayer, because of the weight of the bridge. Now I have 4 XL motors and 2 L motors, those shoud be sufficient to work with a custom brick built master actuator for the arm. Edited March 30, 2016 by Tommy Styrvoky Quote

Many years ago I worked with the British Army Sales team (the only female) demonstrating Engineer equipment Chieftain AVLB and CET we also kept some museum pieces as well including the Churchill and Centurion AVRE and AVLB. Chieftain AVLB would be an interesting model with its 3 stage hydraulic system Quote
