Thanks! With spring quite close I started up on a Wenge 18650 mod, with much more traditional everything. It's good to be past winter.![]()
Sweet sure is nice will you be headed this way for summer?

Yes indeed. I'm not so sure how much modding I'll be able to do as there is a pretty full program set up. Burden of real life I guess....

Thanks much Karl. An actual router is a bit big for these. But a small router bit in a jig on the drill press is quite helpful for these. To work the brass I drill holes in strip first, cut off with a hacksaw, then rough shape them with a belt sander. I've seen other mods that look like the wood and brass/aluminum are shaped at once but I prefer to do them separately, and check the fit along the way.
The switch is pretty simple, there is a length of presta valve with two nuts for the tube, and a 6#32 screw that had the head reduced and threading filed partly away so that it can be pressed into a length of 4mm brass tube so that the pin sits nice in the tube. Then a hole is drilled for the retaining ring. Add a finishing washer, knurled nut and two ring magnets and it is done. I timed the screw and two tube preparation and it is just about 2 hours of patient work, using a drill as a mini lathe.
A koa mod from an earlier pic in this thread is almost done.
Edit: not the first pic.....

Since the right screw and tube were out, I might as well go ahead and make another one:
