Double Bass Grofiller Bass project

I have begun building a Double Bass in my barn/workshop using the Mateo Gofriller plans from Peter Chandler. The instrument is intended for my son who plays in the school orchestra. We currently have a good plywood bass that he plays now but I am hoping a hand carved solid wood bass might have a better, or at least more "interesting" voice for bowing classical music.

Here is where the project gets interesting (or goes astray); I have been collecting old lumber for quite a wile and I plan on using this reclaimed material to fabricate, or "craft" the Bass. The good side, most of the wood is old, very old and rather unique. On the other side, i hope it works and does not prove to be a source of embarrassment for my son. The teen years are hard enough with out being forced to play some crazy homemade bass your Dad built. Anyway I am off to the barn... wish me luck!

First issue, I have some old beams for the top, ( 20+ rings per inch, straight grain) it is not Spruce, but Douglas Fir. I may have to change things a bit to make it work. The wood is bit heavier than spruce (and stronger) so i may try to make the top thinner to make up for the difference or i could adjust the arching (stronger wood-less arch?).

Thanks for the reply, maybe this will be my practice top for learning the carving process. Doug fir has a beautiful color that gets darker with age, It would look good on a bass; but not with cracks. It could also make a nice wall hanging.

This explains why there was no info on double basses with doug fir tops. I did find this on doug fir and violas Invalid Link Removed

CTRegan;

One thing it took me a while to appreciate was that I was going to spend 500+ hours building the bass. (In reality this first one took me a good deal more, because of inexperience, trepidation, false-starts, re-work, etc.)

Saving money by using sub-standard material is false economy at best...the most costly thing going into that bass is your time, and you will spend MORE time, not less by doing things odd--especially when it comes to the top. Beside all this, you want to start with wood that you KNOW will sound good.

I appreciate this post, as I've been wondering about douglas fir as well. I know that some acoustic guitar builders like it and a local guy built a crude looking violin with a doug fir top that sounded very good. He has since died and left a bunch of the wood that he cut and seasoned for the folks in our luthiers group. I'm glad to get Arnold's advice before spending a bunch of time on a top. Would it make good back braces I wonder?

Good luck on the project! -don

CTRegan,

I have purchased 2 basses from Mr. Chandler and think that they are very fine instruments. In fact, I came very close to purchasing a Gofriller copy from him; it was a very beautiful bass and had a nice, orchestral sound. However, the response was rather stiff.

The Chandler basses are made in Canada without huge fluctuations in humidity, but changes in temperature. If you were to select a top that was supposedly stronger than spruce, be careful that it doesn't have brittle qualities that could lead to cracks.

Good luck with the copy! Mr. Chandler was a wonderful man and produced some very beautiful instruments.

Keep the doug fir for furniture. It splits horribly when used in a bass top. I say this from personal experience.

ESPECIALLY old doug fir that's been seasoning for a century or more. It's about as splinter-prone a wood as you can imagine. I love the stuff, but it doesn't want to be curvy. It wants to be straight, holding something up.

Thanks for the advice, it makes good sense.

My thought on the doug fir was, since it was so old and had a previous life as part of an rustic lodge, I thought using this material might impart some kind of metaphysical karma on my bass. It was not to save $$ but to find material that was unique.

What do you mean by the response was stiff?

12" long 2" pipe in sturdy vice, gets very hot close to burner but stays cooler towards the end.
I made some practice bends with scraps. It is hard to get smooth bends without ripples; need to keep practicing.

Upstate NY is pretty this time of year, its hard to believe this same spot of land will be covered with snow in three months time (or less!).
