/diy/ - Do It Yourself

The mounting plate is just a flange that fits a 1" pipe. The caster fits snuggly into a 1" pipe nipple that connects to the flange, so it's a total of 3 pieces.

Here's a pic of an undamaged caster and the pipe it gets inserted into.

I don't know much about casters, so I'm trying to find ones that will fit into the pipe and not need any major modifications to the wood (especially since I'd need to essentially disassemble everything to do more drilling).
