Почему нельзя пользоваться обдирочным резцом для точения чаш!!!Why you don’t use a Spindle Roughing Gouge

DO NOT USE A SPINDLE ROUGHING GOUGE ON BOWLS. My name is Ian Robertson (Robbo) and I have been a production woodturner for 30 years. It is how I make my living turning everything from huge posts to tiny eave finials and everything between and my safety record is impeccable. Our business has never had a lost time incident and we still have all our fingers.
