« Part 6: Cleanup and test fitting Part 7 of Building a brace till series Part 8: Re-cutting the bottom and more test-fitting »

Time to reinforce the other side of the rack that’ll carry the braces. As you might remember, the grain in the pine board that makes up the core of the rack runs left to right, which means that the grooves cut to hold the braces weaken the board, leaving tongues which can easily snap off. I reinforced the bottom of these tongues with strips of walnut.

For a more finished look, I’m reinforcing the top with some 1/8” bubinga veneer, with the grain running front to back. Rather than attempt to cut this to size/shape for each four-inch-wide piece, I cut them all to rough length, then glued them on. It’s 1/8 inch thick, so no special techniques were needed, just glue it on and clamp it with a long board running the whole length to distribute the force from the clamps.

And now I’m cutting them to match the pine board with a coping saw.

I also trimmed the ends of the pieces with a spokeshave. The low angle makes this relatively easy. The only trick was remembering to skew the blade and to work from both ends to the middle. The spokeshave will ride along the wider pine board, making it pretty easy to stop when the boards are flush.

Next it was time to clean up the edges of the grooves. Knife and rasp took care of that.

Next up is re-cutting the bottom board of the carcass because when I trimmed it shorter, I took from the wrong end, leaving the sockets for the sliding dovetails offset about 3/4 inch from the board above it. Easier just to start over on that.

Sort of like very fancy plywood!

We don’t make mistakes. We just create opportunity for practice!

Looking good, this shelf will be plenty strong. Nice work.

Yeah, it’s probably overkill now, but when I was smoothing the ends of the walnut, there was still some scary flex to the tongues. Now they feel pretty darn solid. And the top will look nice, though I’ll probably be the only one y’all enough to see it.

Seems like the plan is working Dave.

Yeah, I’m getting there, Kevin. A few detours along the way, but that’s life.

I hear you Dave, just finished a couple of detours on my dressing table. I botched a shell carving on the drawers front and had to “reactivate” an earlier test carving. Sigh.

Anyways, your project is going to be great.

Thanks, Kevin. Sorry about the carving troubles. One of the reasons I’m building this brace till (beyond just needing it to store braces) is that I’m going to be practicing a lot of techniques for future projects. The mitered dovetail corners on the carcass will be used on the bookcases I’m building next.

I’m not sure what I’ll veneer, but eventually I have a set of antique Art Deco dressers which need to have their veneer patched, and I have some period thick rosewood veneer that looks to be a reasonable match.

The sliding dovetails will be used on other furniture, and the five cubbies in the bottom of this will get drawers before it’s done to give me some practice building and fitting drawers.

And this one is shop furniture, so if something does go wrong, I can decide it’s good enough for me, or try out crazy ideas I might have for a fix, and if it doesn’t work out great, I’ll probably be the only one who notices.

I added the pictures of gluing and clamping the veneer. Forgot those last night. Oops.
