Cranked these out on the Haas Mini Mill. They're mounts for the differential. Bearings press into those big bores, then the part presses onto the differential, and the whole unit gets bolted to the subframe. This means that all my work for the differential subsystem is done, and I just have to focus on the wheel hubs and all those components.

Orf, those are rather pretty :D love abit of CNC work.
Will you be getting them anodised before they get mounted up? because there is some serious tart potential there.

Probably not. Once I get the hubs done, I'll probably get those anodized, so we might throw these in with them. Wasn't really planning on it though.

Id be inclined too. It makes a surprising amount of difference to how they will hold up with bearings in them (nearly wrote bears... i doubt anodising would help against bears).
plus, i mean, shiny :D
I got a load of stuff (well 8 bits) anodised for my final project at university, and i only got charged like £10 a part.
Out of interest, whats it being attached too? (car wise, rather than diff etc :) )

oOOo very nice. Really wish I'd gotten involved in my unis racing team. Didn't do engineering, only did industrial design, but so cool.
Good luck with the build, look forward to more oppo-updates

Those look pretty awesome! Not a big fan of the MiniMill, much more a VF2SS kind of guy.
As a side note, as a machinist at Purdue who has done quite a bit of work with all of the SAE teams wanting things for bearings being machined: did you measure the size of the pocket and check the fit before pulling it from the machine? I've had a number of headaches because someone pulled a part before checking the fit, and they come crawling back to me because their bearing won't fit :\
I think I've posted some of my SAE-related CNC work before, I should post some more machining porn.

how is the team tensioning the chain?
Most teams have moved to eccentric carriers now, which this isn't, also it doesn't look like these would mount to turnbuckles either with is the other usual solution.

spacers between the subframe and these mounts. Much more rigid and easier to make sure the bores are aligned than turnbuckles. That way all the load from chain tension is sent through the mount and directly through the subframe instead of through a turnbuckle.
