Strips between lute ribs

Post by 2lost2find » Thu Jan 10, 2019 2:50 am

I'm about to start bending ribs. I'm using David van Edward's course, and he recommends buying pre-cut strips to go between the ribs. Can anybody recommend a good source? My ribs will be walnut, so I need a light colored wood.

Is that what you use? I'm having trouble finding it pre-cut into strips. Same with sycamore or holly, which are the woods van Edwards mentions.

Am I missing something here? what is the strip size? you can easily rip strips on even a small table saw or band saw.

I don't know. van Edwards in his course makes it sound difficult to get good thin strips, and recommends that a first-time builder buy them pre-cut. Maybe he's assuming a lack of decent tools? What he doesn't mention is that it's actually damn hard to find said strips. Odds are given the limited selection I'll probably try cutting them myself.

As I understand it the strips must be planed all round and around 0.5 - 1.00mm thickness. Sawn is not good enough. Most woods are not stable enough to put through a machine at that thickness unless you have a drum sander. Even then it would worry me.
The ash I can get over here has a fairly open grain, too coarse for my taste. Maple is supposed to be similar to Sycamore and would be my choice.

(I had to edit my dimensions.)

Get yourself a sheet of 1mm thick maple or sycamore veneer, a straight edge and Stanley knife, and you can cut your own lines to whatever width you need.

Woodcraft supply sells unbacked (i.e. no glue) rolls of banding (.024"/.6mm) of various woods.

If you glue 0.5 mm veneer together into a stack - then plane the edge sweet and take a slice off and plane that strip to Imm - then ease the strips apart - you have 0.5mm x 1mm strips.

I make a lot of small strips - and once down to under 1 mm - talking about square edges is just a bit far stretched ! Yes - @ 1.5 mm I can notice and try to put right wonky edges ( ie they go rhomboid easily )

Get said 1.5mm strip and make a channel on a flat board with glued packers tight to its width - so it will slot in and stand on edge for planing with a small plane. I have a board with many long slots in it - that will take either individual strips or pairs or three up - to plane together to width. It just takes some thought !

I've never built a lute but I am a woodworker. Ash is light colored and bends well, that's the only basis for my recommendation. Well, that and I know it's used in lute bowl construction.

I found a big chunk of holly veneer. Pricey, but enough for several lute bowls assuming I don't screw it up. Thanks, guys!
