    My entry for the summer build off 2022 is Sceptre, a headless ultra short scale travel bass. It will be a 4 string of 650mm (25.59") scale, with a 'B string' tuned to E etc.

    The laminate set neck will have maple outers and a wenge core with pin stripes of black dyed veneer either side of 2mm oak lipping. The body is a single piece of spalted beech and the fretboard is laburnum. I've read that laburnum is the closest a native British hardwood gets to rosewood. The knobs, tuners and strap buttons are also turned from laburnum. The timber is all left overs from other projects.

    and I know people here like headless tuners, so here's a close up of the parts so far

    I tune mine with an Ikea hex key - more leverage and readily available.

  3. I like that, but I'd have to have the hex key attached with a chain to stop me losing it.

    Edit - on another I used piano tuning pegs and had a wrench attached with a string.

    I've tried steel thumb screws before but the finger force needed to turn them is too great. These have brass threads and longer bodies. I don't know which of these two things make them easier to turn, but they work.

    Cool idea! Is that piece the second one up from the bottom the laburnum? It doesn't look very laburnum like to me... I've often thought it would make a good fret board.

    Yes, that's the one. I bought a log of the stuff last year and split it. There was a bit of rot in the middle but I got some good pieces from it. It is quite light when first cut. That piece has been out in the sun for a couple of days which has darkened it slightly. It darkens a bit more when oiled.

    I used to turn quite a few bowls from it when I was a tree surgeon, most of the bits I used were much darker than that, with an almost white sapwood.

    A couple of progress pics.

    I mustn't have tightened the router properly because the bit slid up into the chuck. The bearing was only just riding on the pickup cavity template. The result was a chewed up template and cavity. It's now a bigger hole than I intended.

    Holy moly, that was fast! I thought I was making good progress this weekend, but you are knocking it out of the park (which you could literally do with this bass ;)

    It's hard to see in the pictures, but does it have a curved front and back?

    Yes, the top has a 12" radius the same as the fret board. As I'm using individual tuners it will work. The back has a 3/4" round over on the edges. I put the radius on the top to take styling cues from an EUB, but the effect is a bit too subtle to be really noticeable.
