a success!

[Michael Gamble]

Hello Mark and List
Yet another type of wrest pin is "bifurcated" and has a wedged insert. When 
you tap it on the top (with your punch and multi-tool hammer - for Joe's 
benefit :-] ) the wedge is forced up in the end of the pin thust expanding 
it. The down side is you cannot get these out of the block. Found in some 
Brinsmead grands.
Regards
Michael G.(UK)
