Re: Old skil 297 router collet?

It wouldn't be hard to machine (or have a machine shop do it for you) a collet to fit the router. It need not be hardened steel. Just make several of them and if you feel the one you are using is compromised, throw it out and start with a new one. My bet is they would last a long time. They could al...

Re: ala Castelluccia

Very nice Craig. I see you used the standard repro tailpiece. What sort of tailpieces did these Selmer knock offs have originally. I know there is nothing else commercially available that fits correctly as they need to be much shorter than most archtop tails to look right. I eventually came up with ...

Re: Doing the "crease" for a Selmer-Maccaferri model.

Craig, the reason we don't see the hard line on the guitar is the dome. This pulls the crease out at the edges unlike the flat top of the mandolin where the crease continues to the side. I agree, your picture illustrates the hard line I'm talking about. Interesting on such a late guitar.

Re: Doing the "crease" for a Selmer-Maccaferri model.

I think there may be a lot of difference between the true Macs and the Selmers. By true Mac's , I mean when Mario was working at Selmer. By far the largest number of instruments were built after Mario left so those are the ones most studied. I think Mario saw to it that the tops had a true crease. L...

Re: Doing the "crease" for a Selmer-Maccaferri model.

This is a sketch of the clamp. I modified a fan shaped torch tip to give two separate flames to feed the tubes. Basically I just squoze (mashed) it shut in the middle! Also the clamp has wing nuts on the top of the bolts for quick clamping.

Re: Doing the "crease" for a Selmer-Maccaferri model.

I built a clamp from square aluminum tubing (1") that is heated with a torch both top and bottom. This heats a 1" strip which is advanced 1/2" when ready and the clamps screwed down. The top is then bent on a previously scored line and removed from the clamp. The top is thicknessed to .09 - .100" (2...
