Square vs dovetail ways?

[markknx]

Ken,

Thanks for the imfo. Yes I just had mine apart and there is next to no wear in it right now, but when I had it apart the thought of how came to mine (as it dose with machanics) I was not talking of taking material away from the slide area as much as the clamping surface. But I see your point about also scraping the slide surface to true them back up. It would seem shims would either have to have tabs or be glued on.
Thanks again,
Mark
