Re: Current Build - Falcate Braced Multiscale OM cutaway

Very chuffed you got it finished and looking so good Martin.

We were all following the saga and wincing along with you at each setback.

Re: Reinforcing Cutaway Bend

Rod I was thinking about this as I made up cauls for the glueing. I decided that glueing the whole side as laminates would be quite hard. Unless perhaps you use a vacuum press...? Given my difficulties with the sharp cutaway design that I like (based on Trevor's shape) I am still keen to look for ot...

Re: Starting New Falcate Classical.

John that is already looking very smart. That back wood is very attractive. When I tried Aquacote recently I had to use several goes to achieve proper filling. Maybe my technique wasn't so good...? I seem to remember you didn't use hide glue in the past. Has there been a lightbulb moment? Cheers Dave

Reinforcing Cutaway Bend

I am still having difficulty with cutaway bends. On the current one I got a reasonable bend but there were some flats between the ripples of some very nice maple. I decided that since I had already made the side pretty thin ~ 1.7 mm that if I was going to sand the two sharp bends to a smooth curve t...

Re: How to repair Split neck from being face planted

Steve useful log of the neck repair.

I was interested when you used CA to lightly glue down the nut. Is this common practise on steel strings? My experience is with classicals but have made a couple of SSs and simply made the nuts a close fit.

Flamencos - strong back influence?

I was looking at some flamenco players last night and I realised that the very uncomfortable looking playing position they use (when sitting down) tends to leave the back of the guitar fairly free of body contact. This is very true of Vicente Amigo but also of others. So I wondered if this allowed t...

Re: neck thickness/headstock thickeness

Not having a safety planer I set up a jig to do it with a router. As with G&G I thickness the underside of the neck and the head. It is essentially a trough with the neck supported at the shallow angle required, with the router running on the top of the trough. The bolt bar in the heel is useful her...

John fascinating as ever. It sounds a bit mean but I see that like me you still struggle to work cleanly with the epoxy! I am starting a classical build myself on which I shall use falcate bracing, with a cutaway. I initially thought I would simply use Trevor's medium size steel string outline but h...

Re: Dry Climate Build Schedule

My understanding is that guitars can take increases in Relative Humidity reasonably well compared to when they are built. Everything can expand a bit, and particularly the doming of the top and back can increase to absorb this increase in width. (Changes along the grain are small). Note that the top...

Jigs - Are they worth it?

For me Yes and Yes. My first build was a classical with essentially no jigs other than the Solera, and it came out sort of all right. It looked like a guitar, sounded like one, but was certainly not true to the original design and was pretty rough round the edges. (Obviously this would be true in ge...

Great stuff John. Your build threads are always very informative.

Am using 'cedrela' which is incredibly sof...

Re: Adjusting sound

I had a mis-sounding string the other day which took quite a while to find. It needed a magnifying glass to spot a tiny, shallow bevel on the body side of the saddle, causing a sitar effect. Quick file to get a clean beak point fixed it. I was doing a nut set up at the time and was convinced the sou...
