The old seats are a bugger to get out.
Every one is different and I have an arsenal of purpose made weapons, cutters and picks to remove them.
Some come out in one piece but most don't want to play and can take 20 mins or so to extract.
The whole process is a tricky job and I've just spent the last couple of days re-designing and machining a lubricated insertion tool to make squeezing the Viton equivalent of 10lbs of spuds into a 5lb bag a little bit easier and more consistent.
