Re: Parlor Guitar with Tail piece ???

I think of this as being analagous to the output tube in an amplifier. You have a fixed DC supply at the anode with the signal superimposed on it so it goes up and down. The output transformer passes only the Alternating signal not the DC component. The downward component which the soundboard receiv...

Re: Nut compensation on bass guitars

At times, problems with string action(and compensation) at the nut can be improved by keeping the string windings on the post to a minimum so that you do not have an extreme break angle on the string across the nut. This is particularly a problem on Fender style headstocks on the E string and someti...

Re: need help figuring out compensation

I went back and measured what I have on my bass with the Savarez strings.
I would expect that what peter wilcox suggested would be very close

Re: need help figuring out compensation

I built a bass a few years back using savarez nylon core strings. Compensation requirements were minimal, and pretty well straight across. The nylon core has a much lower modulus of elasticity than steel so the tension does not rise as much when fretting. I would suggest you try the strings on an el...

Re: Neck Bolt Alignment Techniques

I thought I could try putting some cut-off bolts on an angled support and grinding the heads to points, screwing them almost flush into the holes. and then tapping the neck into the pocket to create drill guide indents. Is there a better way? Whatever you do, don't screw in pointed cut-off bolts ti...

Re: bridge/saddle placement

Tim, I use the stewmac fret calculator which gives a measurement to the break point of the high and low E on the saddle. Things to watch out for -some people will quote compensation figures to the front of the saddle slot, others to the middle. Either is ok if you specify, but often this is not give...

Re: putting angle to a '59 lp jr build upbow or downbow?

The 3 1/2 or 4 degree angle is a common figure for a carved top Les Paul not a flat top junior For a junior use whatever angle gets you the right string height at the bridge for the bridge you are using AND gives you the right clearance over the pickup (if using a dogear p90) You should allow for a ...

Re: Suggestions on fixing a fingerboard extension on adjustable neck?

Could you drill into the end of the neck under the fretboard to epoxy in whatever reinforcement you use to support the extension?

Re: Trimming the soundboard and the back without a router

A couple of things I have found useful
-cover the rim side of the plane chisel or knife with a piece of binding tape to make it relatively safe from gouging the rim
- a few razor saw cuts to depth in the waist area make it much easier

In sum, then, increasing the break angle beyond the minimum does nothing to help the guitar, and may hurt it. Why do it?
Only to give you some margin for future saddle lowering

I agree, too much is a bad idea and the typical Martin arrangement is excessive

Re: evo "gold" wire advice

the Evo wire is both a lot springier than nickel and the tangs are not as prominent as most so I prefer to have the radius only a little tighter than the fretboard .

Re: migrating top

With that thickness of wood you are definitely at risk of failure without additional reinforcing
Since you are able to pull it back into position the UTB must be loose and will require regluing.

Re: migrating top

For this failure to occur you need a couple of things happening. First you need a crack to occur beside the fretboard, either from shrinkage or from shear failure Secondly the glue joint between the UTB and the soundboard needs to yeild (often from elevated temperatures) It may not be obvious as the...
