Key Bushing

[Farrell]

Hi Jack - do you wish to borrow a set of cauls? I've got most of Bill's caul sets - mortise sizing and other. What size are you looking for - what size are your pins? I think I've done a Chickering before, so I might have the cauls.

I'd wonder if maple would be a good choice for caul making. When I put my mortise sizing cauls in, the key wood is usually a little wet - I'd be concerned that the maple would swell and who knows what size the mortise would end up. But that's just my guess.

If I can help, let me know.

  Hello everyone,

  I am rebushing a set of keys for a Chickering grand and the balance pin holes are an odd size and do not fit any of my Spurlock cauls.
  What do you do in this situation? Do you special order cauls or can you make them yourself?

  I quickly made a set of mortise sizing cauls out of maple and so far they have worked good. I now have to make the key bushing cauls I and II. I will be using maple again because it is all I have and I find it easy to work with. I hope this is a good way to do this or if anyone has any other suggestions please let me know.


  Regards,
