Yeah I would assume a 3/16" rivet every half inch should do you just fine. The current pattern seems to be way overkill.

Also, add some fillets to your pocketing patterns as well. It definitely helps the end mill for the router to eliminate the precise corners that you have going on there. Even more so, if you ran this, it will still have the mill's OD in each corner of your triangles. I would advise you make the fillets to your the mills exact OD or higher; never under.

Also, the normal/nominal thickness I have seen over the past years for sheet is a variance between .090" and 1/8". 1/8" for the beefier parts that require much of the static loads to be held and .090" for manipulation systems. (Correct me if I'm wrong guys haha)

Aside, it looks like a pretty decent sheet chassis.

"While I was a student in FIRST, it was all about becoming inspired. Now as a mentor/engineering student, it's all about making sure learn everything I can so I can carry that on inspiration for future generations while having a hell of a lot of fun!"
