Re: Inherited Tools

Thanks Mark. I like to think I paid a reasonable price for the gauge and some nice small chisels. I work on the principle that you always say yes! A bit of wood or whatever... I acquired some lovely mahogany a while back from a clear out which has formed the head blocks of several guitars. It is a b...

Inherited Tools

I inherited a bunch of drill bits from my wife's father many years ago. Still when I rifle through the tobacco tin looking for the right size I think of him as a skilled mechanic repairing machinery in a factory in the midlands. As an amateur I found it hard to justify the cost of a proper thickness...

Re: Curious about a mode at 146-ish Hz

Yes it would seem time to get some Chladni patterns though it may be hard to excite that one since it is broad and not very tall.

Have you tried tapping with open and closed soundhole? That can help pin things down to the top or back resonances.

Let us know what you find.

Re: Dead notes on 13th fret

Stanley the guitar looks very smart. I suppose it would be a bit cheap to talk about wolf notes!

Anyway do let us know how you solve the problem.

Re: The Australian mandolin quartet

Graham that is lovely work. It would certainly be nice to sell them as a set.

Your book is still sitting in the workshop next to a partially built flat back mandolin which since the heavy gardening season is now over in the UK might actually get some time spent finishing it!

Re: Fox Bender Problems

Yup had the same problem. Spring steel is the answer though since it rusts you need to wrap the wood in Al foil to keep the moisture off the steel. I couldn't find a supplier in the UK and ended up buying from - was it LMI or Stewmac...? Again as Bob says perhaps I just didn't know my way round the ...

Re: Soundboard joining

I use the old fashioned string and wedges method - couldn't find a photo of it in use but you can probaly see how it goes or find some other pics. It is a commonly used method. It will accommodate quite severely non straight outer edges, particularly if you arrange the framework the right way. Good ...

Re: Wood species for Falcate braces

I think I have said this before but for the tightly bent secondaries in Sitka I use 4 thinner laminations rather than 3, bent over a hot pipe. Still get some failuires but mostly that works.

West system epoxy with some filler to increase viscosity gives a nice relaxed time to clamp up.

Re: Epoxy, brushes, CF tow, oh my!

Joel I have been happy with West system epoxy. I don't try to do too much bracing in one go so haven't run into the glue setting on me. For applying I use cheap artists paint brushes. They need to be reasonably stiff and I often need to cut down the amount of bristle. You can get them cheap enough t...

Very nice looking Trent.

I got started on a build from Graham's book but the gardening season opened and it is somewhat paused! Must get back to it.

Re: Crack repair posssible?

Not helping the original question but Mark, when I tried build with Padouk I found it would crack if you just looked at it sideways! Bending the sides was hopeless I just ended with cracks half way along the length. I gave up as I didn't want to send a box out into the world that was so liable to cr...

Re: New Mandolin

That looks amazing. The skill in getting those ribs shaped is very impressive.

I am interested in the fixture a t the bottom. Are strings anchored into it? I have only ever seen a metal attachment point.

Re: New Member intro

Good luck with the building Phil.

If you are anything like the rest of us here you will find it quite addictive. You think well I'll just try one or two to see how it is done and after not too long you are pasting a label in that says number 10!

Re: Quandong and Sassafras dreadnought

Frank I would repeat how impressed I am by the craftsmanship.

On further looking I notice you have used brass bridge pins for the top and bottom strings. Was that to change a resonant frequency?

Re: Cello build

Look forward to it Rod.

I've always thought that the carving of either archtop guitars or the violin family requires so much more craftsmanship than a straight guitar build. I'm not going there. Enough trying to get a 'straight' build right. But will enjoy seeing how you get on.

Well can't say I go for the colours much either, but it looks to be very well constructed. Detailing is absolutely great.

Bending non cutaway sides is fairly straightforward on an iron. Doing a cutaway is something else entirely.
