A little while ago I picked up a smashed Hohner B2 headless Bass. As the electrics were goosed I decided to use it as the bas(s)is for a Single Cut project.

Quite a small single cut

Forgot to mention filled in the old pickup holes with wood, glued up, and made a template for the new ones

Am keeping the existing rear tuners/bridge

Mock up with pick ups, am waiting until got body wing wood shaped and glued on before routing as the pickups go right to the edge. Got a steve bailey fretless circut to add as well.
Next job to get the body wood and shape before glueing. Will keep updating as I make any progress....

I got some plywood today ( don't go to Lavers between 12-1) as they don't cut it when there's only 2 staff on....!

Anyway did a quick rough cut of the body templates and took this photo: am getting the real wood tomorrow!

Needless to say, the finished item will not have the gap between top "horn" and neck and the bottom will be a better fit too...

Nowt wrong with headless, mon ami! I'm liking the way this is going.
Keighley Timber are really handy if you happen to be up there.
It looks like North Bradford is the home of headless ingenuity! This is my project:

Well, here are some photos of some lumps of mahogany: it's hard to believe they are both from the same piece!

I've rubbed them down with 80, then 120 grade, wetted the wood and used 120 again. next is on to finer grades still!

Done quite a bit of body shaping and the pickups have been routed out. Bottom body yet to be thinned down : am waiting to do the control cavity and see how much wood that takes up.

Due to the amount of wood filler this will be a coloured finish......

"How did you shape the contour where the upper horn meets the neck?

I was trying to picture it (before you posted the pic of the back) and I just couldn't imagine it"

With great difficulty: it looks good from the front and back but when you look directly down it goes off at an angle. When I decided to do the conversion I spoke to a couple of luthiers who both said "Dont do it" as the angles are all wrong on the donor bass. Also I shaped quite a lot of the body before glueing it on: big mistake, as the contours flowed better once you have it as a whole.

A lot of the shape was just my imagintion and "following the wood": many a time I've gone back and just shaped it a bit more. If you compare the earlier photos to what I have now you can see the difference.....

Oh and thanks for all the feedback folks, its nice to know people are appreciating what I'm doing.

Re the control cavity: my router bit was too long so had to shim the template, which slipped at one stage( always double side tape both surfaces!!) but all in all quite pleased with the result. I had to use some wood filler in places and you can see where I'm touching in tiny holes prior to final sanding.

This is now the Blue Peter Bass.....in other words I'm posting completed photos without showing any further steps.

I've just got to the bottom of some electrical gremlins , it seems my faraday cage was too effective!

Anyway it sounds very powerful and I think looks pretty cool too: the carbon fibre scratch plate and control cavity cover is actually lookalike foil.
