Well its for a homemade robot. I am looking to rest a U shaped base of pine on it.
Heres a picture:
Obviously that doesn't look sturdy
So I am going to drill said holes in the aluminum to make them sizable for the rods. And rest the wooden chassis on it. And slide two triangles on each side to nullify the vertical difference.
I said it was for our bot because I thought it would yield better results.
It will have a caster btw
