There are callipers and then then there are calipers. The ones I'm interested in today are of the digital variety and used to measure things. Specifically, I want some digital calipers to help me get the thickness right for the top and bottom of my up-coming archtop guitar build project. The idea is that I can use my new tool to measure the thickness of the wood, thereby removing yet one more excuse for me buggering it all up.
Let's backtrack a little bit. This digital caliper project has been on the boil for quite some time. Remember when I made the c-clamps recently? I talked about how I thought that the comb joints I was using for the clamps would work perfectly for a digital caliper. And indeed it did. What I might not have told you at the time was that I cut the wood for the caliper project at the same time that I cut the wood for the clamp project. Crafty eh! Ha ha.
First things, first.
I trimmed down the body to get it all straightened up and then quickly reaslised that I wasn't going to have enough room to stick everything. No problem... I glued on a couple of extra bits of wood. The best thing about this part was that I got to try out my new spool clamps. Ha ha. They worked a treat!
If you look really hard in this picture you'll see that I'm adding a little height to the top arm and a little width to the bottom arm.
I'll end with a close-up of that famous comb-joint that I fashioned with my table-saw. I wonder how wide it is? ;-)
It's a little uneven when you get this close to it, but the technique has worked surprisingly well. I've still got the jig, so I may have another go at something like this in the future.
