If you can get to Hermosa Beach I can show you what we have done over the years.

BTW we stole the above idea from Kingman (team 60) years ago. The only time we had a problem was when a programmer (who shall remain nameless) left our arm against a hard stop when testing a new program version. Of course the motor went the "wrong" way and I wound up rebuilding an FP tranny. Fortunately we had several around.

Thanks. I understand what you're saying about how to do this, I'm just wondering where I'll be able to get the part (octagon stock, that is). I couldn't find anything on google, and my team doesn't really have the resources to manufacture something like this (no CNC machine or anything). Do you have the link to a place that sells/makes this type of piece?

EDIT:

I went to that site but I only see hexagonal bars. Could you be more specific? thanks.
