If you’re considering pour in, your cavities will have to be perfect. A little sanding dust and ca or epoxy hides small gaps in the cavity with traditional inlay.
Unless you have a cnc I wouldn’t consider using pour in inlays.

Thanks for sharing that John.

Not Trevor, he'll have a better answer for sure. I used to statically test my tops/braces before Trevor's book came out. So its been quite a while since I've done it, but I do recall comparing the test to one another when I built my spreadsheet. As I recall the dynamic test (Ala Gore) came out sligh...

Have you considered going over it with just alcohol on a pad and some pressure? It would be like spiriting off in a French polish routine. If it’s really only .002 thick it might do it for you. It’s hard for me to imagine 24 coats of 2 pound cut being only .002 thick, but I’ve been wrong more than o...

I’m with John above, I’ll wipe on boiled linseed oil or some tung oil.

One thing that can help is to heat up a larger area of wood, several inches on either side of the area you’re working to bend. Not just heating the local area where you want to bend. The backer is a good idea also. I think the backer and the ability to heat the entire side is the reason side bending...

Thanks, keeping blops of epoxy of the top is a major win
I did have the holes taped up, you can hear the difference too. Thanks for the reminder, it’s little details like that are easy to forget.

I've been using Trevor's books for a while now, mostly on traditional classical builds. They turn out really well, so I thought I owed it to myself to try a falcate build. This is a 12 fret 000 steel string. It's moving slow as I have another guitar I need to be working on. well, and I'm slow! Here ...

And you get 50% off books and plans.

As the topic suggest I'm trying to mash together Trevors book plan with a Martin 12 fret 000. I notice that when lining up the 12 fret body joint Trevors soundhole is shifted approximately 32mm forward (towards the body joint) this would allow for 18 frets without extending the fingerboard into the ...

Thanks for the thoughts. Dave, I was looking at some taps of another guitar, Also a Hauser size 7 Fan guitar. It has it too. I also has a tap saved of that with the sound hole plugged and it appears to be the first response with the sound hole plugged. Trevor, I tried to get a spectra plot of tha mo...

Whatdaya know, I can attach a gif.

I think having the speaker off to the side is responsible for that. The mode actually sweeps across the top. If I could post a .gif I can show you.

I was fortunate enough the other day to have a guitar scanned with a laser vibrometer. I viewed it as an opportunity to check my tap results. They actually line up pretty nicely. One oddity I struggled with is that most of my taps have a broad peak around 150 Hz or so. I've always thought it as an a...

I am running it on windows 11. Seems to be fine.

I understand that Graham Mc. had some difficulties obtaining permission to publish a number of papers jointly authored by Graham C. and Tom Rossing. Prof. Thomas Rossing was one of the greats of musical acoustics and a friend to many, including me. It is with considerable sadness that I have to rep...

Really a nice job!

That's looking really good!

Hi Mark, I have a couple of photos. The things that helped me most were a wide super sharp chisel, 25mm was my widest, a marking template that can very accurately mark the joint all around the neck and a highly repeatable clamping method for test fitting and final glue up. The photo below is my mark...

Thanks for the nice words guys!

Just complete this. Honduran Rosewood and spruce 7 fan open harmonic bar classical A v-joint on the head stock which was something I've been working on I'm pretty happy with it as it sounds and plays pretty nice. I was pleased that I was able to get the spectrum into the range I was shooting for. IM...

I'd probably bleach it and the add some tint to the lacquer to add a little color back, or possible stain the neck if you're finishing from rattle cans.

Here's one I made some time back. I used a closed cell rubber foam for the seal.

Are you sure your shellac is dewaxed?
I tend to use Kusmi buttons which are not dewaxed, it looks like a milky caramel color until I separate the wax out by filtering it though coffee filters a few times after it's dissolved.
You might try filtering it and see what it looks like.

That is interesting, thanks for pointing us to it.
