Re: Riveting up a frame
We have aluminum pop riveted some assemblies with excellent results.
A good design practice is to use a splice plate or gusset plate at connections between two structural members & install multiple rivets in each member.
For instance at a right angle connection between two tubes, put a triangular gusset top & bottom with 4 rivets thru the gusset plates into each tube.
This also spreads the load over a larger area of the frame tubes, reducing the likelyhood of exceeding material yield at a single concentrated point if using one rivet.
A 3/16 rivet is the same size as a #10 screw. Holes are easy to drill and they are plenty strong for anything on a FIRST robot if using multiple rivets at a joint.
1/8 rivet are great for adding small plates for limit switches etc. or reinforcing structures after it's all bolted together.
