Joe, I'm thinking of a multi-sided mirror, but when I mentioned this new capability to my wife, the painter, she had a few ideas. Going to start with some nice flat pine, cut a groove in it first and lay in some 3/4 inch textured inlays stained a different tone than the base.
And I too am amazed by the workmanship in these jigs. I have one other jig I like using, which is an exact width dado jig for the router that uses a straight edge. Very similar quality, except for the oops where I learned, don't lift the router out of the groove or jig until it's completely stopped. Didn't ruin the jig, but the expensive carbide down spiral bit was retired from service.
One of these days I'm headed down to Rockler and we'll have to have some coffee and a chat. Saturday a.m. they have demos, so we could meet there in Ontario. I like those guys (and gal) at that store. They are always so helpful.
The more I do, the less I accomplish.
