Could someone essentially press a new bushing in with a spare intermediate shaft, then resize it by hammering through a shaft made with the proper OD (same as the expansion rings on the tool)? The resizing shaft could easily be spun up on a lathe.
I know this is an old thread, but yes you can do that. It would require a very gradual taper to start with and the tool would need to be very smooth or polished.
I seem to remember that this is the way it was done when burnishing the bushes on some of the old English gearboxes.
For the dummies who don't understand why you burnish the bush, it also presses the OD of the bush hard into the machined surface of the block. Forming it into every high and low ridge/groove left by the machining process. This gives it a superior grip over just hammering it in and then butchering out the ID with whatever tool you have handy..
