To enable the release of one nice Royce BB that is completely and utterly seized in
I just got it on Ebay, Its still in the shell but the rest of the bike is missing It would have been far easier to remove had i the frame to use for leverage but for the sellers flash of inspiration.
So what i have is a bb shell, titanium i might add with all the tubes leading off it cut through. and inside the shell is the BB.
My plan is to use a bench grinder to initially thin the shell at the bottom , cutting across the screw hole for the bottom cable guide. The reason for this spot is to use the guide hole as a guide to judge on how deep i have cut. When i think its thinned enough ill swop to a dremel with a thin grinding wheel and cut through completely. Then the same on the other side. Due to the position of the tubes i only have a smaller section to cut through.
Im guessing ill have to go very carefully where the threads are before using a hammer and chisel to split it apart.
Before you ask, i have already had a go using a big spanner and the proper Royce removal tool. Any more leverage on it will damage the tool pins.
