How did you make those knobs Alan?
Did you turn them on a mini-lathe?
Wouldn't be to hard to lathe them - just have to get some copper tube for inserts and some grub screws, but I was busy and ordering a bunch of stuff from Luthier's Mercantile anyway - and they have them quite cheap, so I ordered them (and a half dozen in ebony). The switch caps are quite tricky, so I got Roger at THG knobs to make me a pair.
