Re: General Finishes Waterbase Topcoat - SM is pushing this - anyone tried it?

One of my students found us a pretty decent deal on Enduro-Var Gloss gallons in time to handle a couple of necks and a body or two. Jet.Com (Walmart's rebranded web sales engine) has a 15% off deal for first three purchases, but capped at $30 total savings...so two gallons at about $150 total, versu...

The question was referenced to classical guitar bridges, which suggests woods close to Brazilian rosewood in mechanical characteristics which do not reside on the current CITES lists. Given classical buyers are even more sensitive to departures from a narrow range of appearance options than retro Ma...

Thicknessing Jig for Peg Head

This is the second version of this jig, with the first being a full adjustable jig that could be finicky to set up. The current version is designed to produce a parallel rear peg head surface and mill the outline of the dart/diamond volute/neck transition at the same time. I use one of these for eac...

Re: Hot hide glue for binding repair

Sure the binding material was ivoroid? LP binding seems to be ABS or ABS/PVC alloy, which can glue poorly with Duco. Titebond is the common answer here, but after seeing repairs fail within a year or two of repair, I use CA Gold low odor and wick it in, then wipe off excess. Unless there is no topco...

Re: Primer on getting started with hot hide glue.

Acetic acid works for Titebond, fish, and hide - pretty much any AR/PVA or drying animal glue...the commercially available De-Glu-Goo glue remover is gelled acetic acid, and is very handy for vertical surfaces (otherwise, soak a paper towel with white vinegar - dilute acetic acid - and place on the ...

Re: Primer on getting started with hot hide glue.

I have been using fish since 2007. Key differences are: - Longer drying time - Longer clamp time and more precise fit needed - Tougher clean-up, but still easier than Titebond - Heat release is a little more difficult...hide seems more predictable. - Drying glue, so new fish glue bonds with old/dry ...

Re: Titebond over Titebond repair work or Titebond as main repair glue?

Titebond is a curing glue, so the cross-linking that occurs as the original film dries does not reoccur when fresh glue is applied to fully cured glue...you end up with two distinct layers of glue with reduced tensile and shear values. Abrading the old glue helps quite a bit, as it provides some imp...

Re: First binding instalations need a fix.

Fish is easier for binding for folks the have not done much hide, and the long, long open time makes final fitting of the back's neck butt joint doable on the body. Hide can be used for binding, and with a little warming after the bindings are on and the bands in place, will provide the same degree ...

Re: Primer on getting started with hot hide glue.

Its worth pointing out that the water bath temp is going to be 10-15 deg F warmer than glue temp in a loosely-capped jar for Proctor Silex/Rival pots...150-155 degree F water temp (measured about 1" off the bottom with digital candy therm) generates about 135-140 deg F glue temp at the bottom of the...

Re: Titebond over Titebond repair work or Titebond as main repair glue?

For cabinet makers, the rule is apply Titebond to both surfaces, which might be more about porous end-grain leaving too little glue in the joint than how the stuff wets out. It does hold pretty well, and I still use it for lots of cabinet work, jigs, fixtures, and stuff that does not need a lot of s...

Re: Primer on getting started with hot hide glue.

A Saltan plate warmer (check Ebay) and a heat gun can ease your transition - warming braces, bridge plates, fretboards, and bridges makes thing a lot easier. Over time, as you get both more comfortable and more efficient in your use of the adhesive, fewer and fewer glue-ups will need warming or supp...

Re: Titebond over Titebond repair work or Titebond as main repair glue?

While it might seem odd to make repairs on a guitar using hide or fish (or CA) built with Titebond, but it's always an improvement. Failed bridges - either due to glue line failure or hot creep - is common, and a reglue with 315g hide settles the issue. I'm not certain that - other than a reglue on ...

Re: Titebond over Titebond repair work or Titebond as main repair glue?

For a failed joint where the failure occurs primarily in the adhesive layer (a cohesive failure...glue left on both sides of the joint), the type of glue used matters. Titebond is a thermoplastic, curing glue - it crosslinks as it dries - so trying to reglue a failed Titebond or other AR/PVA glued j...

Re: First binding instalations need a fix.

Rubber bands are from SM - a lb for about $22, which is enough to do a guitar...these last a few years before atmospheric degradation does them in. Unlike rope or tape, the force exerted is constant and - as long as the glue allows some movement - will pull things in nicely. The bands are the best o...

5/8"/.625" is what seems to be the upper limit and 9/16"/.563" is the lower. For most steel string peg heads, there's no real issue with break angle, so some variation in string hole height is not a big thing. Like Bob, I shoot for .595"-.605" prior to finishing on paddle heads and .750" minimum for...
