Lillian, I do put a rough longitudinal shape on the top of the 'parabolic' braces before I glue them to the top. As you can see here they are not all the same profile. http://www.anzlf.com/phpBB2/userpix/99_002_2_1.jpg The peaks of the 'parabola' are in different places according to the position of ...

Not sure who makes Sting's lute, looks like it could be a Wadsworth, not one of mine though. I'm ambivalent about Sting, on the one hand he absolutely murders both the lute and Dowland, bit like asking Liberace to play Chopin, his playing lacks any subtlty and his voice is totally inappropriate for ...

Colin, My apologies for mis-reading your intentions. It was just your comment after Bob's mention of Al's corker guitar. I totally agree with your comments about 'pseudo-science' and I often get frustrated by people on forums who claim folklore as scientific fact, such as: "The advantage for the lu...

Yes, have used broken glass many times as a scraper. On my lutes and historic instrument repairs I never use modern abrasives so all smoothing is done with glass scrapers. Custom curved scrapers can also be manufactured as needed. Score the glass with a cutter then snap along the score. The opposite...

Geophysicists...a strange breed. Theyre not hard to spot in the office...they're the guys wearing bright coloured braces and a bow tie.

OK Bob, on your next guitar let me see you mount the back and top plates using rubber gaskets, if damping at this joint is unimportant. I'm afraid there is a lot of mis-placed pseudo-science being applied in luthiery now, take a scientific principle, apply it to a system for which it isn't designed ...

I did used to do it with hide. Do it in a warm room and warm the parts with a hair dryer, put the glue on with a squeezee bottle, back plate on and rapid application of go bars. With practice, which is the secret, it can be done fairly easily. Playing the hairdyer on the edge as you put the bars on ...

I use a router for my slotheads now, having always done them by hand before. My wife bought me one of Luthier Tools slothead fixtures for classical and steel string recently, which has made the task a doddle. After shaping the exterior of the head put it into the fixture, then drill the tuner holes....

I've never had the slightest problem using tru-oil over z-poxy. It has always worked perfectly with no grains appearing on the surface, just a perfect smooth tru-oil surface. Like any other finish it does need to be used properly, it's not a magic system. But, if the z-poxy is allowed to harden off ...

Another great little instrument Dave. I think it would make a wonderful pub guitar. Another to add to my 'to do' list. Or of course you could just send it to me after Cheltenham, Suzanna would understand.

Your folder on my music player is getting quite full now.
