if we crank down on the bolt, the walls of the alumiunm get crushed. how do we do this without crushing? not cranking as hard might not be a good idea as we dont want axles wobbling around.
and drilling a massive hole on one side of the alumiunm so we can fit a nut through that is an option but will take away structure from the square, as 1in sides means a lot of surface area taken away.
anytips from the veteran teams? btw our pillows are steel or zinc or sumthing. not aluminum so welding that on would be complicated. if possible,. i dunno

The magic of wood - wherever you need more support for mounting things to your frame, cut square blocks of wood, sand them down to size, and use a mallet to tap them into the aluminum for a nice press fit. Then drill and fasten away. Doesn't add much weight, either.
