Things With Strings

After having all three layers done, I decided to try to get the middle layer (shallowest) to size using a router and template, then I would glue all three layers together and machine the outer two layers using the middle layer as a router follower bit against the middle layer. In short this turned out badly, as I broke the middle layer whilst trying to route the inside surface. Fortunately I was able to patch it up, and in the end the patch should be invisible, but I decided at that point that it was probably best to get the three layers glued together before I made an unrecoverable mess of things. glued and clamped I'm not 100% sure how I will shape it yet. Probably router plus jig for the outside and sanding drum for the inside. Part 2 is here

Things are moving a little quicker now due to being able to square-up the stock faster due primarily to a jig I made for that purpose, hence I managed to get two layers done for the banjolele this weekend. I'd planned to work on the banjo rim, but avoiding nail holes, knots etc. left me with insufficient pieces for an 11" rim, but plenty for an 8" rim. Each layer is quite different in density and cloud, but I'm hoping it will hold together and look decent. The layers were 1" deep, as opposed to the 3/4" of the first one I made. The first one was quite yellow in colour, and I think I'll use that as the middle layer. It will probably end up looking like a cheese sandwich. Two layers glued and clamped I'm now quite looking forward to the next steps which will involve ensuring each layer is flat and then gluing them together. I'm not sure yet whether I'll sand the layers flat or try to use the router, I'll have to sleep on it. Part 3 ...

After a few practice attempts (aka false starts) at making rim segments last year, this weekend I had my first proper crack at it. The problems I'd run into previously were mainly due to starting off with non-squared stock material. This time I picked a ropey log from the pile of pallet wood I have (allegedly Mango, but could be anything) and squared it up. This particular piece was not the best, mainly consisting of knots, nail holes and worm holes and a little bit of wood holding everything together. I don't want to screw up on something that was too nice, but what started off as a fairly substantial piece only yielded enough wood to make one 12-segment layer for the banjolele. Anyway, once I'd squared up the stock, I needed to cut the segments at 15 degrees on the mitre saw. The calculation to get the correct angle to set the mitre saw for segmented is (360 / #segments) / 2 which is where the 15 degrees comes from in this case. First problem! My mitre saw had fix...

Continuing the banjolele neck I started yesterday (link here ) I couldn't wait 24 hours, so after 23 hours I took the clamps off. Actually, the reason was that I needed the clamps for my banjo neck, and I figured 24 hours was just an arbitrary number anyway and that if days were 23 hours instead of 24 it would have said 23. Anyway I digress. I hadn't got the clamping 100% right, because although the joint was good, the head was very slightly askew, so I cleaned it up on the table saw. I will sand the top level though before fixing the fingerboard. Here how it looks now. The scarf joint is very hard to see, it starts somewhere close to the fold on the cloth that the neck is laid on. I have to say that I'm fairly happy with it at this point. the neck after gluing the scarf joint

Delayed first by bird table, and then by the flu (not bird flu), I wanted to get back to some building. I took some measurements from one of my son's ukulele's and drew up some sketches for the banjolele in order to get the dimensions for the neck, and got to work on the build. First off, I cut off and cleaned up a piece of mahogany that I had. It's probably not real mahogany, just something in the same family. The piece I cut off was about 19" x 2.5" x 1.5" cleaned up neck blank Next, I made a jig for the table saw that would allow me to cut a scarf joint at a 15 degree angle for the headstock. I wanted this cut to be clean, so I put a decent Freud blade in the table saw. It actually turned out pretty good. 15 degree scarf joint jig Then it was time for the glue-up. This was a bit tricker than it looked, as it really wanted to move around when it was clamped, but I managed it in the end. neck and head clamped together Another 24 ...
