Re: Is primer necessary?

A primer is a base coat usually employed to improve adhesion between the surface and the top coat. A sealer is similar, but it's purpose is to seal the surface. A pore fill is a little different, it's purpose is to seal the pores in wood that has pores. Primers are not generally used on wood, while ...

Re: Thicknesses you prefer on Parlor Guitars?

That really depends on the specific pieces of wood you're using, but here's some ballpark numbers.
Top - 0.10" to 0.12"
Back - 0.08"
Sides - 0.07"
Bracing - 1/4" to 5/16"

Re: fret levling - radius block or straight edge

Another alternative is to level the board itself along the string paths, including the desired relief. If the frets are uniformly seated, no fretwork is required.
I usually do have to dress a few frets, but nowhere near a complete leveling.

Re: mesquite

It's a little heavy for a neck, but I did use it on a mostly mesquite guitar for a friend of mine.
I like mesquite for backs & sides, I've use it a couple of times.

Re: Fretboard inlay advice

The other option is to recess the pearl enough to completely cover the top with CA. It can be built up with several layers, and sanded to the radius of the board. Having a "cover" of CA over the pearl does alter the appearance slightly, on some types of pearl it looks better to me. Test it out on sc...

TruOil does not dry on Pao Ferro without it being sealed with shellac. I've also become sensitized to Pao Ferro, and don't use it anymore.

Re: How to pop the grain on walnut

In my opinion, the best way to accentuate the figure is to sand the surface very smooth, at least 600 grit and maybe even 1000. That may cause adhesion problems with many finishes, but it works nicely with TruOil, which is my first choice of finishes.

Re: Burst and French Polish?

The key to French polish over a sunburst is using a water based stain/dye/tint on bare wood. Mr. Condino hand rubs the colors to make the burst, but you can also spray the colors. I've done it both ways, spraying the colors with an airbrush was easier for me. James IS a wizard, and he's very open to...

Re: 12" single radius vs. 12"-16" compound radius fretboard

As your diagram shows, there's not much difference. The difference is really the amount you have to remove from the frets. No matter how you radius the fretboard, it's ultimately the string paths along the tops of the frets that have to be level, and the closer the fretboard is to level along the st...

Re: Fret buzz..where to start

I'll be working on a guitar that has fret buzz on the E6 string, frets 2, 3, 4 and 5 only. Barry's right, chasing them down one at a time will be unproductive. You don't need to do the whole fretboard, just the E6 string path. The first fret is a little low, or 2-5 are a little high, so level those...

Re: Making my first steel string acoustic guitar

Randolph is right on with his advice. C&N and a set of plans will give you a good chance of building a playable guitar that will sound pretty good. What he didn't mention is the option of spending 300 hours to build and $200 on tools. Having the proper tools saves a lot of time. As an example, a rea...

Re: Amps for setups

That depends on what you mean by "testing pickups". Anything is fine if all you are interested in is seeing that they work.
If you need to hear how they sound, the answer is more complicated.

Re: question on gluing titebond joint back together

In the context of guitars, Barry is right. It may be acceptable in some types of furniture, depending on the joint. If there's no tension on the joint, it might hold. I still would not recommend it.
