I needed a good pickup for the guitar to sound decent, but also to have a sort of reference: something to compare with when trying out the various pickups. I decided to go for a couple of Seymour Duncan pickups, I bought for my first T-beam project, but later put in my strat.
The pickups are wider than the T-beam, so in order to fit them in, I had to cut through the sides of the steel box profile. That was easily done with an angle grinder (my favourite tool these days, with cutting disc as well as flapdisc for shaping wood).
That's put rather a halt to my progress. I'll make some brackets and beams to straighten and support the box profile in its weakened state. I was going to make pickup holders anyway, but now they're also going to add strength.
Btw, I'm condidering this oil bluing process for the box profile. And, I'm making some mahogany forearm and thight supports (and a strap horn), so I can ditch the acrylic body, that I've grown a bit tired of.
