I would be interested if you happened to have a photo essay on the rope binding process just lying around that you wouldn't mind sharing.

Tools for checking intonation?

What do any of you use to get a decent read on intonation?

So far, I've only tried the Peterson app for iPhone, but those numbers just swim all over the place. I have to believe there are better tools out there.

Re: New bridge made a huge difference

Dave: Like everything you do, that looks great. At this point mine's just a trial, so I didn't do anything fancy with it. It's just a 1/2" thick piece of white oak, 5" long by 7/8" high. The 1/2" thickness is just enough to accommodate the 4.5 degree saddle slot, but that obviously leaves a chunk of...

Re: New bridge made a huge difference

Yes, that's the only thing I can figure too, although how exactly the abr-1 was contributing to the problem is beyond me.

In any event, the wood/bone bridge has a warmer tone than the abr-1 did, so there's a plus as well.

New bridge made a huge difference

I fit my second archtop with an adjustable bridge (abr-1 and a wenge base), after being dissatisfied with the sound of a completely wood bridge. The sound quality became much better---more articulate, better sustain---but a touch metallic sounding. But I've always had tuning stability issues with th...

Re: re-occuring glue-up nightmare

That's what I do too---hardware store CA (seal coat of shellac) and tape. Works like a charm. I'm sure there's something I'm doing (wrong) that makes the shellac necessary, but I never had any luck with CA and wood until I started using shellac. It seemed to me that the CA wicked into the unsealed w...

Re: re-occuring glue-up nightmare

In order for me to be able to use CA on wood, I've found that I have to seal the wood first. I usually use shellac, but thin CA works too.

Re: Headstock angle and break angle at bridge on an archtop

Alan: I had wondered about doing something like that---setting up the tailpiece in a fashion so it could be raised/lowered. The drawings I did suggested that for every 3/16" you raise or lower the tailpiece's point of attachment at the heelblock you change the break angle by one degree. For what tha...

Re: glue of choice for laminated sides

I made my recent ribs from a 3-ply lamination: inner (poplar) and outer (maple) plies 1/16" thick each, and sandwiched between was a single piece of 1/64" baltic birch plywood, oriented (grain-wise) at 90 degrees to the inner and outer plies. No need to worry about cracked sides. If you spread your ...

Re: Archtop deflection testing

I'll pile on here too. Dave: You gave a formula for determining downward force in a different thread just recently, which differs quite a bit from the one I'm using. Your recent post: The formula for downforce is Downforce = 2 x T x sin(breakover/2) where T is total string tension. I've been using: ...

Re: glue of choice for laminated sides

I've used the Better Bond brand of veneer glue to laminate sides. It came in different colors (light, medium, dark), and the light was pretty thick, sticky stuff (if it was Titebond I'd have thrown it away---suspecting it was old). I wasn't able to get a large area rolled out without it ending up a ...

Re: Materials for jig making.

I would agree that plexiglas OUGHT to be a good template material, but I have enough difficulty finding things in my shop. The last thing I need is templates made from invisible materials.

I would think the most useful information the Janka scale could provide us with would be the suitability of a given wood for use as a fingerboard.

Re: Second dometop archtop

Thanks, Mark. About the tune-o-matic bridge: I made a wood bridge for this guitar and for the one that came before it. In both cases, the sound was slightly muffled (for lack of a better term). Both were made from wenge. Maybe wenge is not a good choice for bridge woods? Also in both cases, when I c...

Re: Second dometop archtop

One last note on this project. I changed the base of the bridge about a week ago to the version pictured below. Doing so actually made a noticeable improvement in the sound. I don't know exactly how to describe it, but by comparison, the lower strings---especially the 5th and 4th---are now a little ...
