Re: Walnut Classical - Chuck Tweedy

I'd give my eyeteeth (or a bottle of scotch) to be at the next GAL. I'll certainly be trying to be there, it's been far too long. Us old farts can test out each other's walkers.

Re: 12 fret 000 / 14 fret body shape

Andy, This may be a total red herring, and I'm working from memory of about 10 years ago but: Through a subsequently fortunate mistake, I once made a 14 fret neck for a 12 fret OOO that obviously screwed up the bridge placement. The solution to that particular problem ended up being (if I'm remember...

Re: Brazilian rosewood square piano lid

If there is an unobtrusive spot you could sand down through the finish to the wood, if it's BR, it will have a beautiful chocolate odor with a hint of roses to it that I don't believe any similar wood will have.

Re: Brazilian rosewood square piano lid

As I assume you know, if the flat surfaces are truly solid Rosewood (which the ink, age of the piano, etc., would suggest) then yes, you could likely find a market for the solid wood on any of several guitar builder sites. Even solid wood of 1 1/2 x 6 x 3/8 would find a home in a guitar as bridges. ...

Beautiful guitar Chuck! And thanks for the memories… A local mill here is one of the largest processors of black walnut in the country, running some 1.3 to 1.5 million board feet of walnut a year. By chance, I got to know the head sawyer pretty well and after explaining in detail what was needed for...

Re: Ugh! Big Bad Router Screw-Up. Suggestions Please.

I would also recommend instead of the tape on the bearing, put the tape on the guitar where the bearing will ride when you recut the replacement tail graft. That will "shim" your bearing out the same distance that tape on the bearing would, without all the hazards that tape on the bearing risks. Tha...

Re: Outdoor glue for deck railings

Bob,

Have you tried checking to see if there is an EAA (Experimental Aircraft Association) chapter near you? That might be a way of obtaining a smaller amount of resorcinol. I know the group here were very outgoing and helpful back when my wife had her RV-6.

Re: Doing fret board and head stock binding -questions

Peter, This might be too much bother, especially for a one-off bound fretboard, but if you plan on binding them down the road also, may be worth the trouble of making the jigs. Using this method definitely has made fretting a bound fretboard much simpler and easier for me, leaves no tang exposed to ...

WOW Chuck!!
That is going to look spectacular against the spruce.

And your fit sure looks amazing too. Can't wait to see it when done and finish on it. Is this for family?

Re: Glue for colored veneer marquetry in spruce top

Chuck, I've a friend who has done extensive marquetry, and so I called him to see if he had any advice. He said he has been happiest just using regular DAP wood glue or you can use titebond. He said he has less problems with it than using HHG and hasn't had problems with shirinkage. If you do have s...

Re: Glue for colored veneer marquetry in spruce top

Chuck, Is there any chance you could use the technique of cutting an identical trough in polyethylene and in your top, like has been mentioned a few times here for laying up rosettes? That would let you take your time fitting your veneer pieces for minimal gaps, and then once the whole inlay is done...

Re: First Cello Build

Tom, A couple other things: It may not be a factor with your project, but with the guitars, it's best to support the plate at the node lines, and drive the top with the speaker over an area of maximum movement. It looks from the picture that the plate is laying on top of the frame of the speaker whi...

Tom, Wonderful thread. Thanks for sharing this with us. Have never done a bowed instrument, but would a jeweler's saw using regular blades like you would use for cutting pearl work better for the sound holes? I've used them on wood for a lot of different things and they work well. I would think a 3-...

Also demonstrates pretty clearly why to bridge across the junction of the X braces. htt...
