Frame?

[DonRotolo]

Almost the same way you might connect two pieces of wood. You can put a piece of wood inside the tube for a few inches to reinforce the end and give you something to screw into. It should be a tight fit, but not so tight it splits the tube open.

There are many other ways too.

Thanks everyone very helpful we do have a welding shop and several mentors that have worked with tubing before so i think we can pull it off if we plan it right and build it right!

well welded frames also tend to be stronger, which is quite a good idea for this game

However, poorly welded frames can reduce the strength of key joints by a significant amount. Losing your temper with 6061 tubing is a huge difference in all measures of strength.

Welding is a good option IF you have access to it. as well if a well breaks at competition for any reason you have no way to quickly re weld and get your robot up and running again. I would highly encourage having a back up pre planned for any issues in your frame.

The next best option this year will probably be Gussets with 10-32 bolts through. With rivets and gussets you have the ability to determine which rivets or even bolts shear and replace the part with a larger bolt, or replacing the rivet with a small bolt.

with the amount of abuse that I see coming from defenses so far a very strong frame is going to be necessary this year in order to prevent bots from breaking every match.
