But with the grain of a keyslip running along its length, I would think this effect would be negligible, owing to the tendency of wood to expand across the grain very much more than with it. That said, I still can't account for why some keyslips warp in, some don't warp, but I don't recall one that warped out. It might have more to do with how the wood was dried or how straight the grain is? Also I wonder if there is some historical reason why the back sides of keyslips are unfinished, while so many other case parts are varnished both sides.

I don't understand why the manufacturer does'nt do this. Can any give a reason other than expense.

And I think I rather covered that end of things in my first post.  But here it seems that a jury-rig solution is being proposed as a fully viable long term fix and thats where I part roads. I mentioned that factories dont do this, and dont for obvious reasons. Whilst I have no problem in looking at solutions for problems that are not necessarily standard factory procedure, I cant ignore that virtually all factories through time have opted quite consciously to not bush the key slip on the front rail of the action. Finally... come on guys... there are plenty of ways of doing a permanent fix of a warped key slip without bushing the thing. And there have been several suggested...even quick fixes that will most often work.  A temporary rig in a jam is one thing. A good long term fix that doesn't compromise or risk compromising soft shift function is another. Cheers RicB </blockquote> </blockquote> </body> </html>
