I purchased what is turning out to be a very nice find: a type 6 Stanley #7 plane. Altho it was gummed up with so much black paint that I couldn't read any embossed numbers, it is in very good shape except for the knob which was split in half. When I got it, the knob had previously been glued (with hide glue I hope, but not sure) and string was wrapped around the knob. The knob is now in two peices - a clean split.
Should I put it under warm water to see if the glue is hide glue and just dissolves? There is not much glue left on the two sides; in fact the 2 sides fit quite tightly together.
I understand that rosewood is an oily wood-- what type of glue would be recommended for a rosewood knob?
Thanks for the advice, Skip
