Re: saddle height/ neck angle

actually I´m going to take your advice but did also change something (but reversible :) ) I put a veneer of 0.6mm under the heel which raised the action to about 4mm. With this I can reduce the saddle height to around 4.xmm if I go back to an action of 3mm. That makes me feel a bit more relaxed as I...

Re: saddle height/ neck angle

and perhaps in addition: it does have falcate bracing with fully compensated nut and saddle, bridge similar to the one in Trevors book

I just strung it up yesterday. The neck relief is around 0.1mm and yes it does have an adjustable trussrod

saddle height/ neck angle

Looks like I still need more practice with classical guitar building. This is my third classical ... and every time I manage to make my life a bit more interesting. This time the neck angle is not correct. The resulting saddle height above the bridge is at the highest point almost 6mm. Action is a b...

dewaxed (hard) shellac on top of waxed shellac as sanding sealer?

Hi, I think this is a newbie question but I don´t know and as this guitar is for a customer I don´t want to risk problems. I hope someone here can tell me if I can use hard shellac on top af a waxed shellac with pumice as sanding sealer. Up to now I alway just used the hard shellac to fill the pores...

Re: compensation spreadsheet question

Hi Greg, nope, I didn´t. I actually nowadays work with the textbook value to get a good start and then do the optimization (routine for an existing guitar) to get as good as possible. Not the best solution but at least it worked for my guitars. Too bad Trevor never reacted on the question. Perhaps h...

Re: pinless bridge question

Thanks for the answers. I have to admit I never saw a pinless bridge in real life, only some pictures. I even found one here in the forum: a post from Jim Watts from 2018. Looks actually a bit like the Breedlove bridge. But for example it´s not clear to me how to get the angles for the string channe...

hi guys, I have my third customer finally :) But he has some special specifications. One of them being a pinless bridge.

all mahagony 000 (salvaged wood)

I found some old mahogany stair steps online for forty € and decided to see if my Record Power bandsaw was up to the task of sawing my own backs and sides (which is btw a first, never did that before).

Perhaps that would have been the better solution. I went for two marriage strips and a few diamond patches. Almost forgot to take a picture so had to do it just before closing the box.

I am trying something new. Ok, not for most of you new, but for me. During the last almost ten years I built around 20 guitars which admittedly are now a lot better after finding Trevors books. But I actually never did a cutaway. So at the moment I´m thinking about buidling a cutaway version of my 0...

What do you do with such a set of top panels? The deflection method will also not work on those. Is there any way to still use them?

Thanks for your reply Trevor. For the sitka I found a small mistake. After correcting it I got the same result. So that seems to be ok. In the mean time I also checked with the deflection method and found quite similar results. So for this time I think I can trust the values for the target thickness...

Ahh, I forgot: you need the box size for the guitar

a=520mm
b=385mm

If I use the values from table 4.5-3 I can reproduce the target thickness.
