I have always struggled with putting a bevel on the underside of table tops. It seems like all the jigs that help you with this procedure take some effort to put together - at least more effort that I have wanted to exert.
Well, here's my simple, safe, and quick solution! I'm very happy with it. It's certainly not pretty, but it works better than I could have ever imagined. The bottom plywood provides zero clearance safety, as well as the upper piece of ply. The blade is buried into the upper piece of ply allowing the safe use of both your hands during the cut to keep everything nice and tight against the fence. I was a little nervous that the fence wouldn't be high enough given the 3/4" bottom piece of ply. But that wasn't a problem at all. I elevated the second piece of ply so that it would "pinch" the board the whole way through the cut even after the bevel is cut. Worked perfect! I'm so glad that I finally have a fast, easy, and safe solution to this nagging issue in my woodworking life.
I'm sure I'm not the only one to have done something like this, but I don't recall seeing anything like this before so I wanted to share it with those who might have similar struggles (Now watch, there were 15 posts on this very thing that I missed ). I’m sure you could improve this jig a hundred and one different ways, but speed and end-product was key this time.
Have a great day!
