How to measure and pattern a design? 
This is open to all who've done this, but mostly to Tom B who's made plans for public use.

I have a 1977 Conde Hermanos Esteso that I refinished and the guitar is tremendous. I was thinking of using it as a model for my next guitar, but am curious as to how you get measure thickness for the backs and sides, soundboard braces, etc., when you put designs to plan, such as the Reyes model.

Any tips would be appreciated.

Thanks

There is a tool designed to get thicknesses of wood inside instruments. It uses a small magnet and a rather strange tube looking device then when pulled it clicks at the point of the woods thickness. here it is

Ouch...Pricey! Thanks for that link.

Why is it no one can spell dick here? Is it that bad a word?

Sheesh....

I don't believe it! I posted the word and it's all ****!!! Good thing we're SO politically correct here!

Doncha' just love this Modern Era?

Hahaha i just noticed from your post and looking at my post what you are talking about! most amusing. it is pricey but all fine and accurate measuring devices are especially analog ones. this wont help you the height of harmonic bars and possibly wont be too helpful bracing height. but for me this will be different for each top so you can adjust these. just using a mirror and looking by eye you should be able to make a rough estimate.

If it's a spruce top you can use a strong light to get the bracing pattern but remember not to leave the light on too long!

Hi Ramón

The tool is called Hacklinger and it is sold not only by ****.biz

By the way, the obviously obscene word in english is not obscene in german. It's a german company and the name means "thick" or "fat", so therefore i don't mind to mention the company's name here it's just simply:

http://www.dick.biz

O.k. its automatically censored. No way to post the full name here. I find that to be exagerated. O.k. let's try again. Maybe it works that way. Forget about the underlines:

http://www.d_i_c_k.biz

They offer a lot of useful high quality tools for the guitarmaker.

regards

Armando

StewMac also sells Hacklinger gauges, but not cheaply. While we're on the subject, does anyone know why Hacklingers are so expensive? I know how useful (and nifty) they are and don't know of any other tool that can perform the task so well, but these things aren't made of gold. I know they're precise and probably not sold in great quantities, but the price still seems high...

Ramon, if you can access American Lutherie's publication #96 /winter 2008, there is an article by Alain Bieber about how to make a thickness guage. He says it's very cheap and can be built in a couple of hours.

Cheers, Dave

I use a Hacklinger gauge for most of the top thickness, and pliable eraser; like modeling clay, to find the thickness and shapes of the fan braces. Also, I roll it out in a a long roll to get the distance between the braces. Also, I use a bright light and I tape the outside with 3M correction tape that does not hurt the finish on the top, and then mark the brace positions with this technique.
