Guitar
The aluminium bars have arrived
 
The flat bars of aluminium, which I ordered, have arrived. If I arrange them as a T-beam and add the other components I have already bought, it looks like this.

The guitar is almost complete, right? All that's lacking is some wood.
Not exactly. I can see the following steps ahead of me:
- Plan exact geometry of the T-beam.
 - Decide/calculate placement of bridge and pickups
 - Cut and route top flange
 - Cut and route bottom flange
 - Bolt and epoxy glue the two flanges together.
 - Cut fingerboard and epoxy glue it to top flange.
 - Mount frets.
 - Design and make locking nut from a piece of brass.
 - Level and dress frets.
 - Drill holes for bridge and mount bridge
 - Put on strings, test how much too high the action is.
 - Route recess for lowering bridge.
 - Cut wood for neck and body
 - Sand wood parts
 - Stain and oil wood (I'll probably use spruce for the first version, but I'd like it to look like walnut).
 - Mount wood parts.
 - Wire electronics (pickups, pots and jack).
 - Mount electronics.
 - Mount strings.
 - Play.
 - Adjust.
 - Play some more.
 - etc...
 
If you can think of anything that I've left out - or a better sequence of steps - please let me know. I haven't been explicit about it in my earlier posts, but I've never built a guitar before.
I guess it'll take more than just a couple of months before this can actually be called a guitar. That's all right. I'm not in a hurry.

Two-layer Aluminium Neck
Among the drawbacks of my old T-beam designs were the lack of a truss rod or similar system to control the bow of the neck. A way to help this - but still use stock aluminium beam for the guitar - could be having a neck in two layers - an upper flat beam,...

Stick Bass Pictures
I've made the spine of the  two-string, nylon string, fretless piezo alu T-beam stick bass. Now I have to stick some wood and some piezo pickups on it. Some photos:  I will shorten bot ends of the T-beam down to the tuners and string holes. Btw, these...

Making My Own T-beam
As mentioned earlier, I've had an unexpected hard time finding a suitable T-beam. There are lots of them available, but none wide enough for me to make holes for the pickups without intersecting the top flange completely.
 
 For now, I have given...

A Different Tuner System For Headless Designs
The guitar I'm planning at the moment might be the first in a series. If it turns out well and the building process is fun (the planning sure is), I expect to build another one. And probably then another. And so on. If the guitar turns out sounding...

Alternatives To The T-beam
I've tried quite a lot of places to get the crucial component, the T-beam. It is more difficult than I originally expected. I've tried a couple of scrap metal dealers and the leading Danish metal distributor. Plus a couple of web-based stores....
