Construction with gussets and bolts

[mrmummert]

We mainly use rivets with the Versa chassis...but in some areas we add
bolts as insurance incase of rivet failure if we have the weight and space
for them. We don't tap the Versa chassis for them. The only time we tap
any structural part for bolts is if we use 80/20 as part of the frame.
We've been able use both in the same robot. The past two years we've made
the basic frame from Versa chassis and added other structural parts using
80/20 by bolting them to the Versa chassis.
