I LOVE Kevin Ryan's A4 Kerfed lining - for install it is a breeze and it looks wonderful.

But... when I route the pockets for my braces I'm having all kinds of issue with it chipping out.

Anybody else?

Suggestions?

I've tried scoring with an exacto blade, but it didn't help.

Are you climb cutting? That might help.

I just tried it for the first time and really like it. I'm a die-hard when it comes to doing stuff myself and this is the first pre-made lining I've ever bought. It sure does go in like a breeze but I haven't routed binding channels yet.

edit: Misread your post. I was thinking is was the binding channel, not the brace pocket. How are you cutting them? I score the edges with an xacto and rout with a 1/8" bit. A smaller bit would help.

I've scored the locations and cut with a 3/32 bit - still getting chip-out in places.

I love this stuff, especially the cypress.

Does a little chip out on a liner even matter?

I guess I never had this problem because we scored with an exacto knife and then cleaned out the brace pocket with a little chisel. Viola! Clean as a whistle. I think the router might be overkill because the material clears so easily with hand tools.

If the side of a brace enters the linings right on a kerf, you can get chipping. Happened to me with reverse kerfed linings, too. So, when a brace is going hit one of the kerfs, I take a sliver of kerf width wood (a shaved down toothpick will do), dip it into some glue and fill the aforementioned kerf. That has solved my chipping problem. Oh, and I also pre-score the linings where the brace edges hit them.

Actually, Hans, a little chip on the lining might not matter to some. Each one of us has to answer that question for ourselves. For myself, and a lot of others, a chipped lining is not acceptable. For others it is.

Maybe if you routed from the inside out? Clear the inside so there is no wood to catch to tearout?

I've got nothing against hand tools but this is a great job for a router if all your brace ends are the same height. The router cuts the same depth quickly and with no measuring. And it's a lot easier if you don't want to cut through the sides.

I use a trimmer with a 1/8" bit: you have to climb cut to avoid tear out.

Paul,

I think Kevin recommends putting a strip of tape along the lining to prevent the chip-out. I had the same chip-out problem as you the first time I used it .... then I read his instructions

Try sawing on the lines with a razor saw to the depth of the bracing, then routing the section to be removed out.

Tape will do the trick...or hand tools.
