Warren in Lancaster, PA
>I use a coping saw for waste removal. I don't think it quite fits in the kerf-maybe I hit the kerf running and saw a little as I go down. If you use a fretsaw with a more delicate blade you have to be more gentle with the saw. I would try for a smooth and deliberate action. It may seem odd to go slowly learning a technique that is designed to save time. Also if there is plenty of tension things go more smoothly.

I got a coping saw for Christmas in 1958 and broke the blade in the first minute of use. But last week I used a fretsaw to cut out some complicated foliage appliques in walnut without even thinking that the blade might break. Light at the end of the tunnel.
