Hi Andrew, I am dead against the alloy sleeves. Under no circumstances use them. I bought some when I started in 1975, and was completely dis-satisfied with the results, and never ever used the remainder. If you have to remove the pin, to do anything, why not try a larger pin. This of course after checking the hole, to make sure there is not a split in one of the laminations. If there is a split, then shim with either sandpaper (grit side out), or some of that veneer, that has a backing. Hoping this helps. Regards, John M.
