I am using some bird’s eye maple on a jewelry box lid, edge gluing it to strips of the same walnut with which I’m making the box.

When I try to joint an edge for gluing, I get tear-out from the maple burl. I’m down to ripping off 1/16 of the maple in order to get a good edge but am not satisfied.

How can I get a glue edge with burl which wants to chip out, even with a very small depth of cut on the jointer?

Thanks in advance

This is a nasty problem. I’ve run into it myself with quilted maple. The answer is, sharpen your blade (no, sharper…sharper still) and take the thinnest pass you can, or sand it (ew, bleck, never mind that’ll look horrible).

Another solution might be to switch out the jointer for a card scraper.

If none of these work you might want to build a jig that allows your router to work overhead like a C&C machine, and take the smallest bite (1/32nd, 1/64th, 1/can you even tell it’s cutting?) you can with your sharpest bit. This is a significant build just to get wood smooth, but once you have it, you’ll find uses for it down the road I bet.

Thanks for the ideas. I believe I’ll try the router idea in which both boards are edged in the same pass. Since it’s a glue joint, I don’t think sanding is the way to go.

I tried the “smallest bite” idea on the jointer before I posted. It works to some degree, but still chips out on the corners, which makes a divot when it’s edge glued.

I’m going to try your idea and make a jig.

Thanks for taking the time to reply.

If you cant beat it, how about epoxy with dye?

I have been using Sam Maloof’s idea of sawdust and glue. It’s a pretty good way to go, and easier than messing with epoxy.

Better would be not having to deal with the tear-out.

conifur, what’s the name of the company that sells the various colorants for epoxy?

I have used a drum sander to flatten pieces that don’t play well with the jointer.

I use a drum sander to “plane” for thickness if I only need to remove band saw marks. What I’m having trouble with here is chip-out on the edges when jointed.
