Re: First Cello Build

Tom, A couple other things: It may not be a factor with your project, but with the guitars, it's best to support the plate at the node lines, and drive the top with the speaker over an area of maximum movement. It looks from the picture that the plate is laying on top of the frame of the speaker whi...

Re: First Cello Build

Tom, Wonderful thread. Thanks for sharing this with us. Have never done a bowed instrument, but would a jeweler's saw using regular blades like you would use for cutting pearl work better for the sound holes? I've used them on wood for a lot of different things and they work well. I would think a 3-...

Re: Loss of bass lowering the saddle?

Kind of an old thread but this might help picturing the reason for all the advice of take any thinning of the braces slowly, as you get close to where you want to be, very small changes can have very big effects. Also demonstrates pretty clearly why to bridge across the junction of the X braces. htt...

Re: Choosing the correct router type

Nick, I don't do electrics, but if DeWalt routers are available in NZ, I don't know how you could beat the 611 compact router. The depth adjustment is incredibly accurate, and has features that are really useful for guitar work. I do wonder about the Kauri for the body though. It may just have been ...

Re: open discussion about binding/purfling fitting

Thin CA here as well. The fumes are not toxic, but are highly irritant to mucous membranes. Setting a fan on low to blow across the work area at 90 degrees works well to avoid the eye burn, etc. of the fumes. I do pretty much as the others describe, with some variation. The tips I would add would be...

Re: Glue spreader applicator

Chuck,

Have you tried just letting the glue harden and then pull the dried glue off in one piece? Usually comes off easy that way.

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?

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 ...

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.
