HI Larry
thanks think Joe had a Morso and found some tear out on the back side. I have one but its only the mitre one so it cuts a V only. NO tear out, I didnt even put fresh knives just left what is in it in but you have to cut the V before the slot for the panel or it can break out there. Its a bit archeic I know however have my reasons for now.
this was the moore head i had saved and bailed after I enquired with a company that made me a moulding head in the past up here. THeir point was good forget it on my cabinet saws now a 1" arbor becomes sensible. If they still make them they had a right and left tilt model and can see its three knives and corrugated. THe Magic moulder was two knives and pre made carbide, two diff options
