Re: Gummy Zinsser SealCoat

Try hand sanding again after another 24 hours. Use good no-load paper, and start with 220. Have a dry towel next to you as you sand, and just swipe the work a couple times then run the paper on the towel to clean the paper. Also dust swarf off the body frequently as you go. If the shellac is good, t...

Re: Gummy Zinsser SealCoat

2 things right off the bat: 1) Are you power sanding? Shellac melts very easy so aggressive power sanding always loads the paper even if the finish is good. 2) Overnight may not be enough time - particularly if it is cold. Is there a date on the can? Because this all could be from old shellac as wel...

Re: A few questions about early martin necks.

Hey Clay, Now that I look back at the article it is a bit complicated because Freeborn describes 3 separate methods to do the joint. One using a bandsaw and jigs, one with a table saw & jigs, and the final is by hand. Prior to that Greven showed his method using bandsaw (for the neck-shaft work) & r...

Re: back to the drawing board!

Shellac will get beaten up by the strings very fast. It is not a good finish for things that get lots of hard wear. What Mark is saying is that he finishes the back of the neck with shellac (FP probably) because it has such a nice tactile feel. On the board surface (between the frets) you are much b...

Re: Low temp finishing & shellac questions

" 3) On your next guitar like this, do the filling and a couple of initial top coats before routing out for the Maple binding. Saves rosewood juice stains.

Re: A few questions about early martin necks.

The Martin "diamond volute" joint was covered extensively in issue #102 of American Lutherie (Summer 2010). Greven wrote up his method in half the article, and Charles Freeborn wrote up his method in the other half. It's a great article.

Re: New Cordless Drill

Really went on and on.
But they had some cool amps in there. :P
I did like the "fack" word that was all over the text.

Question for Louie: With my handy little 12V, I can drive big screws and stuff, what do you need an 18V for?? Building a deck or something??

Re: Cutting Aluminum Extrusions

"as you say, they often have abrasive blades mounted when used for cutting ferrous metals." I've always referred to this type of cutting machine as a "burn saw" - it's very appropriate, if you have ever used one. I should add that I've cut a lot of aluminium extrusion with a 12" miter saw (DeWalt) ...

Re: back to the drawing board!

I'm no expert in the dark arts of solid-body guitars, but...
From what I do know, Fender (and most others) finish a maple board after it has been fretted, then scrape the finish off the frets.
That's all I know. :-)

Re: How to get super high gloss w/ French Polish?

I would use CA. If you drop-fill with medium thickness CA - accurately - into the holes, Then scrape that down very carefully... You can get a pretty good fill that will not have a strange color. I was going to suggest pumice, but that will not work well if the fill has to be totally clear to look g...

Re: Cardinal Lacquer

Barry, did you follow the link that Clay put in my thread of the same name - about a month ago?
The people on OLF seem to like it. I'm planning on getting some, but I build so slowly, there may be another product on the market by the time I get there. :-)

Re: Shellac over furniture oil?

Bryan, you may be able to get the oil out of the wood by washing with a solvent, however, this is not going to help the situation. The real problem is that Old English Scratch Cover (which is what Amy has recommended) also has a dye in it. A very strong, dark brown dye. That is never going to go awa...

Re: The wood on my guitar is crumbling slightly, help?

Yea, wood crumbling to dust is pretty gnarly. I'd like to see a picture to figure out if the wood it totally rotted out, or if it is some other problem.
Could it be that the screw stripped in the past and someone did a poor job of filling the hole with a crumbly filler (like Greg said)?

Re: Tapping threads in neck for bolt on

This reminds me of liquid hide glue.
It will work, but if something goes wrong - it will fail catastrophically.
Then you will have to replace with a barrel bolt or a threaded insert. AND replace a broken FB and any top damage.
So, why not start there??
