gluing ivories

[Joe And Penny Goss]

Hi Jim, It is not the moisture that causes them to curl HUH!
But rather the lack of correct clamping tools. The old fellers used a water based glue.
Sometimes, if the head has just come off and the keytop is free from hand soil, one can just rough up the top of the key, keeping any glue dust , and add a tad of water to re constitute the glue. Then clamp over night.
The calls for the head have a ridge that the clamp butts up against lightly forcing the head towards the tail and against the key stick.
Once the glue is dry the ivory will not curl.

  Hi gang

  As one who definitely has more to learn than to instruct, I have a pesky 
  problem to share . .

  What glue system do you use to re-attach ivory ( heads, usually )
  I found out the hard way decades ago that water based glue does not work 
  with the ivory, as it causes it to curl.

  What is the most effective way to get them to stay put, especially when on 
  site with only a few to fix . . ???

  Inquiring minds want to know . .
