FP finish repair

This is a replica of an 1840's Martin I made from a photo in a book. It was the prototype for a few I made quite a while ago. When I first finished it, I just did a quick French polish to somewhat protect it so I could take it around and show it to friends to see what they thought, then finish FPing...

Re: Shop air filtration build - Advise welcome

Nice job Chuck!

Also noticed you probably have the only garage in the US with sound baffles . Is that to block the sound of you working from leaking into the house? I would think the kids are old enough they have probably heard all those words before. Or is your playing the problem?

Really sorry for you both to have gone through what you have.
As you can see, we are all glad to have you back on the forum. You've been missed, and have a lot to contribute.

Re: matching the chayotiance of a four-piece top

You got it right Bob, "flip" it to the "other" side. The other Bob is also right. Whenever I did this, I always had the straight edge of the cut out waist piece to abut to the straight edge of the opposite side lower bout, and the "bump out" of the cut out protruding out beyond the rest of the board...

Re: "Kelobre"?

Peter, Really pretty rosette. If it's pithy, which a lot of spalted wood can be, you might want to "toughen" it up with thin CA before putting it into the top. Just use a small amount at a time so that the glue doesn't Chernobyl on you and turn white. And don't forget to paint the trough in the top ...

Re: Shop air filtration build - Advise welcome

Oh geez, Walnut Rescue. I'd forgotten. not to sidetrack the thread, but I gotta ask, do you still have the video of when you were resawing it and trying your best to cover your surprise at the un-oxidized yellow wood that appeared?
I'd give my eye teeth to watch that again.

Re: Shop air filtration build - Advise welcome

Chuck, May not apply to your garage shop situation, but I remember many years ago Mario posted about his system. It involved using the space between the studs as his ducting. I think he converted the door of a floor level cabinet to hold the filter(s), so it drew off the lowest air in the room, had ...

Re: Osage Orange slab- yes, no?

Osage Orange has been discussed quite a few times here. It is considered by many to be a dead ringer acoustically for Brazilian Rosewood, though obviously not visually. do a search of the library, that's what it's there for, and I think we forget how much really valuable information is there. Here's...

Re: color change of Cherry sapwood and maple?

Brian, I've used a fair amount of cherry, (5 pieces of furniture, and redid the bathroom in cherry, and a couple guitars), and really love the stuff. But it darkens unpredictably so I would make your ascetic choices on the other characteristics, like your quartersawn rays, sapwood pattern, etc. My e...

Re: Laminated neck glue

This might be off topic, but make sure your middle lamination is thinner, or else wider than whatever truss rod channel you will be subsequently cutting into the neck. If the center lamination is the same width as the truss rod's bearing end, you can end up with the force of the truss rod being a sh...

I don't see how you are going to keep them at 40% relative humidity. And how do you sand out the scratches...a walk on the beach?

Re: Need some advice on fingerstyle guitars

Tim, What you hear, whether it's a guitar or someone's voice, or the birds chirping, no one else hears in same way. The same for them. Every single person's hearing is completely unique. Seeing comments, good or bad, is, and should be, meaningless for you. What they think they're hearing is no guide...

I've used similar stuff called Friendly Plastic and have found a lot of uses for it over the years, and with it being reusable, a jar lasts forever. Makes great cauls.

Re: Odorless mineral spirits as lubricant for French Polish

Wow Bob...one of the best typos we've had around here in quite a while. Let me suggest a beard and dark glasses.

Chuck,
Want to add my " great to see you here again" to all the others. Good to see you building again.
