I built a new Franken bass recently & wanted to use a cheap modern bridge that was chromed, I thought that if I could remove the chrome with a gas torch & patinate the brass? beneath, it might look interesting as the bass in question was to look weathered. I heated up the saddles first & saw a dimensional change as the thing distorted, let out a puff of gas & collapsed. when it cooled down It was just a blob of white crystal. ! has anyone else tried this ? what a load of rubbish !!!!!!!
I had the idea for a while to build an industrial looking bridge from a lathe cog but the only ones I have are for my lathe for screw cutting & needed. I did have a massive cog from a mangle & have used it, best I could.[attachment=224302:DSC_0006.JPG][attachment=224303:DSC_0033.JPG][attachment=224304:DSC_0047.JPG]
as you can see, the cog wasn't ideal as the internal holes cut the corners off. I am finally getting the hang of silver soldering though & got a couple of brass sections to fill the gaps. The saddles are made from a steel which has an addition of another metal to help the finishing & is heat blued, the brass has been patinated to roughly match the iron that the cog is made from with a Gunsmithing patina ( which stinks ) the saddle grooves in the base were cut on my mill, a bit deep actually, if I do another one like this I will just skim the surface. The worst bit on this project was machining down the back of the cog. Iron needs a very slow cut & the shape has probably helped to knacker the bearings on my lathe. All in all, though , quite pleased for a first attempt. The bass itself has an ash body which is quite small, the electronics are passive 1x V 1x T & the pup is one of mine, a split-p 4 coil humbucker with a 12 K ohm output. for more images of the bass you can find it here .
