    Yep. Holds a BMW 335I rear bearing. Plan is to use the bearing, hub, and axle assembly from the 335i to cut down on custom parts. And its easy to replace.

    How did you end up deciding to use a BMW 335I components? I like it, but just want to understand.

    The inner CV mounts flush and the outer has a stub on it. Some are the other way around or have some goofy inner CV style. This allowed me to keep the inner CV to CV dimension narrow which narrows up the suspension etc. I think i measured about 1.5" of plunge also. and 65$ each! SURTRACK / TRAKMOTIVE BM8754

    This probably would not be a good option for a long travel buggy since the cv doesn't have great articulation, This build only needs 6-8" or rear travel.

    Starting the mount for the rear end (yellow in picture). The center bearing carrier will mount to this bracket and swivel to adjust chain tension. Starting with a 10 lb block of hot rolled steel! And yes I'm using some of these parts as an excuse to become more practiced at machining

    I enjoy whittling away 80-90% of the weight out of billet blocks.

    Good looking work.

    I've used a few. NX, Inventor, Creo, Solidworks. They all get the job done, but after spending 1000's of hours using CAD at work, for my personal copy I bought a lifetime Solidworks license. I spend much less time on SW trying to figure out how to navigate the interface and more time focusing on the part or assembly. NX is great because the part file is the same as the drawing file. I love the mouse gesture feature in SW, just flick the mouse in a direction to get a different tool activated, very fast. I've been meaning to make a short vid on how I make part models to help take some of the intimidation out of CAD for the guys who haven't tried it yet. I know these videos are out there generally, but it would be cool on a minibuggy part.

    Got it done, took about 4 hours, not too bad. from 10lbs to 2.7, Missed a fillet, but it should be fine. Nice to get all that work on the rear end on the frame for the first time. If I break this assembly I'll be very surprised!
