I have looked at a ton of plans to build one and the received an email that showed the Leigh Super FMT Frame Mortise & Tenon Jig on sale at $399 versus the regular $599 price. So is it worth it or can I build a suitable jig for a good deal less? At this point I don't see angled joints to be needed but you never know what future project will present. Another thought I had was I see tenons on long board such as bed rails and wonder how they get those long boards cut. I mean I've seen plans for mounting routers on their sides and can see how that works but what about the Leigh jig? Anyone with experience using one of these? The Pro model at just over $1K seems a bit too much but I haven't seen a way to compare the two. A call to Leigh may be needed soon.
