To send you off until we meet in January, here's a pic of some scraps going up in smoke tonight.
Building a better world, uke by uke.
This is my building diary. I build ukuleles in my apartment workshop. I try to label the posts, so if you're interested in anything in particular you might find it by clicking the labels.
Feel free to contact me if there is anything you want to ask, or even better; tell me.

Resonator assembly
Well I do have a lot to show today. Now it's time for the backs to go onto the resos.
I took a few minutes to superglue some tiny bits of kerfed lining around the perimeter of the bodies, to stop the backs from sliding around in the glue. I haven't done this in ages but it is very good practice to do it.
Then spread the glue. I'm using my finger though sometimes I use a tiny rubber roller.
After both have glue I sandwich them together with a thick piece of foam between.
The foam will even out and distribute the pressure. The nice thing about resos is they're flat and so sturdy - they can handle some serious clamping.
I even rememered to clean up some squeeze out from the insides. I'm not bothered by a little glue but I know others are. So I thought why not.

Pore filling with chalk
I gave up looking for finely ground pumice and settled for chalk. I did some experiments recently on the walnut tenor (which sadly seems to be lost in transit near Ipswich) and now I'm turning my attention to the little koa soprano I'm making.
It had two wash coats of amber shellac a few days back, enough for me to see the pores. I was a bit braver than last time, I simply used the muneca almost dry to smear the chalk out.
As you can see the back turned dull and greyish. I kept rubbing for a while, using the chalk as an abrasive. Then when I had chalk powder in the pores I brushed off the edges (where a lot of powder had gathered) and loaded the muneca with shellac.
And wiped down the back. Then I did the sides and the top. Much trickier, the sides are curved and the top has both the bridge and the fingerboard extension blocking the way. But here's a pic of the back. I might repeat the process but actually most of the pores seem to be filled already.
