After experimenting a little with covering plywood edges using hardwood recently, I faced the problem of how to make the hardwood edges flush with the plywood. I tried using my block plane, but that didn’t work out that well, so I looked up for a solution on the web. Here is the one I liked:

It wasn’t too hard to build, even for a novice like me, and it gave me a chance to practice some router skills.

I like that, and it looks so easy to build. I think there should be a “JIGS” page in here.

Great looking jig! I love simle jigs. They always seem to be the best.

Bradford: we had this conversation already. I guess for now we will use a “Jig” tag.

-- Happy woodworking!

Thanks guys.

Chris, yes I have. It worked out as expected even though it’s still not fault proof. The router will not tip by itself, but the whole platform will, unless you press the handle carefully against the workpiece at all times. I routed into my hardwood edge at one point because of that.

That seems really tricky to hold on to. You have to press one hand against the jig and the other on the router and make sure the pressure on the router doesn’t overpower the hand on the jig as you slide it down the edge. Its probably ten times easier to epoxy an angle iron to the edge with a spacer strip (for clearance) and clamp the whole thing to the board as shown in my sketchup below. Just make sure your clamps don’t get in the way of the router bit. The good thing about this is that w/ a flush trim bit, its pretty hard to mess this up. The bit can only pivot away from the trim.

Interesting post, sitting on the front page, yet appears to be from 2007. Nothing wrong with that, just none of the links work anymore.

Maybe it’s not really as easy as I’ve always found it to be, but I have had huge success using a flush trim bit with a pilot bearing. I like to use jigs too, but for flushing up edging I never thought it necessary to make one.
