My Doctor Who bracket assembly is very worn and has a lot of slop. I bought a new bracket assembly and rollers and I plan on swapping everything out. But something like you've done would make things more durable than just putting back the original rollers that are known to wear.
My question is, did you use any off the shelf parts for this? I assume the bearings are a part you purchased. You mentioned making washers and the brace for the bottom so I'm guessing you have access to a machine shop. Doesn't look like this is something I'm going to be able to tackle.
