Hello all, I have the chance to look at wood turning. a man sent me a link for a brace, as he uses it for fly fishing due athur-riris. has anybody made one, or know somebody that made similar? this would be used with my bad arm whilst wood turning. using the chisels. I would think holding the chisels would be Velcro etc. any help or guidance will be appreciated. thank you ATB Bri
