When I built my current brew rig 12 years ago I used full locking casters with expanding stems. Recently I noticed the casters were looking a bit "bow legged" and when I removed one of the caster assemblies I found the expanding polymer insert had majorly broken down.
Fortunately the polymer inserts are available separately for a couple bucks each so I ordered a set of four which arrived two days ago while I was up north fishing. So this morning I stripped everything off the rig, rolled it into the adjacent carpeted family room, flipped it on its side and started replacing the inserts.
Here's a bad one accompanied by a new one.
Eventually I found they had shipped me one undersized insert, shown on the right of the proper sized insert. It's a subtle difference, roughly an 1/8"D difference, but it would not expand enough to provide a solid grip.
After giving castercity.com a peeved phone call to arrange for a correctly size replacement to be shipped pronto, I took the best two of the old inserts and trimmed them on my table saw to make one correct length insert, and was able to get that to work for now. Got the rig all put back together, and if I had any empty kegs I'd get set up for a brew tomorrow, but I don't, so it'll have to wait. That's a high class problem for sure
Cheers!
