Who was it here that did stabilizing? Or maybe I don’t even know if that’s what’s needed, per day. I’m cleaning up one of my grandfather’s planes and the wood knob and handle are intact, but oooooooold, a little cracked and I fear potentially brittle. Do y’all think if I were to basically soak in some clear resin in a vacuum, then clean them up, sand them back to the original shape and perhaps polish them up, that would save the handles from falling apart?

The plane in this pic. I’ll try to get better up close pics

From looking at the pic, the crack in the knob wouldn't be sealed with the stabilizing process used on our knife scales. I'd guess that it could be submersed in epoxy under vacuum then have the excess epoxy cleaned off before it's totally cured. That might seal the crack.

Kinda what I was thinking too. Thanks Mike.
