Re: Gore method/Tap tune/Siminoff...help!

There are much better qualified people who could answer - but here goes. I have no experience with that tuner so don't know, but see Martin's comment above. I was talking about testing the finished, strung up guitar so how you put it together doesn't matter. (Trevor does justify his method in the re...

Re: Gore method/Tap tune/Siminoff...help!

For checking after the build is complete you need to be able to examine the spectrum so as to identify the first three resomances as Jeff says. Trevor describes how in detail. Many of us here use VA software for this. It is free and runs on Windows. It is not trivial to learn how to drive but there ...

Re: Flamenco guitar

You guy are seriously luck to have that blackwood available. I keep seeing pics of it from Trevor to a half dozen other makers and I love it.

And that is one seriously nice looking giutar.

Re: Fly in Nitro Finish

Jim thanks but it is that removal that is a bit tricky. It is a small insect and has been pretty embedded in the finish. I ended up sanding it out but that leaves a fairly big area with finish removed. And OK that's alright I can respray. I felt that trying to use a sharp implememt would likely leav...

Fly in Nitro Finish

I spray just outside my workshop door since I don't have a booth. As it is warming up here the insect population is growing so I do tend to pick up the odd small insect as I did today.

Is there a good way of dealing with this?

Re: Introduction & 1st Build

Stuart that looks really neat.

I keep facing this issue of the rosette. I would prefer to not use a commercial one but I also don't want to spend what would probably be weeks doing a traditional one. That one looks good.

What are you using for the bridge and saddle?

Slow neck carving

OK so who else will admit to taking ages to carve their necks? I have a cedrella neck on the bench for a cutaway classical and I have spent hours and hours on it. I keep going back to the section in G&G but I simply can't work up the confidence to take those huge facets out down to very near the fin...

I don't know about a slow build Wayne it seems to be going pretty fast to me! And jolly nice looking too.

It is probably not of any significance but Microsoft's SmartScreen filter doesn't like your photo site for some reason - had to turn it off to look at your PDF's.

Re: Just Finished Falcate braced Osage Orange\WRC classical

Thanks for the detailed reply John. I'm pretty sure, thinking through your points, that my issue has been too thick a top (and also perhaps too thick a nitro finish)

I was thinking of retopping my last one but I will try thinning the top before actually removing and see if I get anywhere.

Re: Just Finished Falcate braced Osage Orange\WRC classical

John that looks great. Photo reproduction doesn't give a very real view but the Osage looks fine. Lovely grain pattern. And As you say, over time any brashness will calm down. The overall aesthetic works well. I like the heel shape. It is a bit of a regret that since I decided to always make cutaway...

Re: Fresh off the bench Blackwood/spruce classical (PIC HEAVY)

Nice crisp work Steve. The blackwood is indeed lovely. I particularly like your heel shape. That is the style that I used to aim for but unfortunately since I now always do cutaways I'm stuck with a rather formless round shape. But I love the access to the upper frets. What bracing are you using? An...

Re: Side bend question...

As Steve suggests I go down to 1.8 mm for the cutaway side. If this is really your first build it is perhaps worth noting that a cutaway is significantly harder to do than a straight build. Everything from bending the sides, shaping the linings, fitting the bindings, shaping the head block etc are a...

Tapering the Neck

In the latest GAL mag Mark French shows some photos of Charles Fox's workshop and there is a very nifty way of supporting the neck when tapering it on the bandsaw. The problem is that you can only really mark out where the fretboard will sit on the top of the neck. But the heel and headstock means t...

John I like that you are doing a cutaway classical. I have decided that by default I will always do a cutaway since as a player it is so much nicer to use. As an aside, as you probably know Pernambuco is/was the favoured wood for violin bows. Usually looking darker than your sample. Stlll sticking w...

I saw this idea somewhere but since I can't remember where I can't attribute it.

Since I was doing this job today I thought I would try it and it seems to work really well.

This is a form of mandolin of course. There is an interesting chapter on it's development in Graham McDonald's book 'The Mandolin a History'

As Jeff said. The bridge rotation test in the book is very useful. It has pinpointed a classical that was overbuilt for me recently.
