Do you by chance have access to a laser cutter?It's welded? Oh that *****.
Would be better if it was machined with drilled holes and threaded for capscrews. Countersink them. Would look much cleaner too. 1/2" aluminum would be better, but prob heavier. As you cab see, I'm a CNC machinist myself.
Sorry, I don't. What did you have in mind?Do you by chance have access to a laser cutter?
