David,

This gearbox was made for our 2010 robot. The only reason for the extra four standoffs are just so the gearbox stays together at all times. The other four standoffs are just purely for mounting.

If I was going to do this again, It would not have as many spacers.

Thank you for sharing. You have been busy. If you did this with SolidWorks Photoview 360 you really should put this image up on www.solidworksgallery.com. Very nice work. Marie
Marie,

It was indeed rendered with Photoview 360, I'll definitely put it up when I get a chance.

Chris,

The reasons why I use 1/4" Plate over 1/8" Plate

-Stiffer
-Can be tap'd
-Thickness for bearing
-Allows for counterbores

Also, what exactly is the plate thickness? I need to know for a project I'm working on. Nice gearbox btw.
This is 1/4" Plate.

Thanks,
