Cheater Video: Cutting Tenon Shoulders
A few weeks ago I posted a blog entry about using a flush-cut saw to slice tenon shoulders. I must have written it poorly because several readers requested a video of the process. So here you go.
A couple details and thoughts:
1. You can use a chisel to help position the saw’s guide on the work. This is especially helpful when dealing with angled shoulders. Here’s how you do it: Drop the chisel into the knife line for your shoulder with the tool’s bevel facing the waste. Slide the guide up to the chisel and secure it with a clamp or hold-down.
2. Be sure to use a flush-cut saw that has no set to the teeth. A saw with set will mangle the guide.
3. Take light strokes with your saw and use light finger pressure against the wooden guide.
The results speak for themselves. The shoulder above is straight from the saw with no cleaning up. This technique allows me to split my knife line, or obliterate it if I so desire (and I do desire it , on the shoulder that will face the inside of the work.)
