Re: Mak a Shooting Plane?
I wouldn't worry about a metal mouth. I find most heavy soles, or special mouths are a wast of time, and I have planes that date back to the early 80s. That might be part of the problem as if one enjoys making planes one never seems to have so few around that any one gets too work out. I have only plane that I have worn out two soles on, and it takes very little time to replace a sole, so I don't let it worry me.
Three options to metal are:
1) Make the plane and fix it when the time comes. It will take about the same time either way, so why bother until the need shows itself.
2) Saturate the mouth with epoxy or crazy glue to harden it off.
3) Make a mouth out of diamondwood/pen blank.
