Excellent!

Any instructions as to concentration? % solution, etc.? I will definitely use this on my next instrument.

Incidentally, Michael; you may remember a conversation we had about ten years ago, wherein you stopped me as I was carving a viola top, because I was trying to follow your instructions about carving violin tops...and I said that I wondered whether that was why many players had commented that my early violins "sound like a viola"....

Anyway, an update on that is that my wife, Ann, suggested that I try stringing one of those early "violins" as a viola. I used the bottom four strings from a five-string fiddle set (thus having the right tension for a violin-sized instrument), and it made an astonishingly good 14" viola. Your observations as to what makes a good viola versus violin sound were spot-on!

So, thanks again, Maestro Michael! Smile

Chet

I don't remember.... maybe one part of glycerin to 4 or 5 or so parts of water? I usually just do it by eye.

Anyone else?

I've been using about 10% by volume. That solution needs to be used fairly soon or it will grow undesirables. Once the moisture is dried out of it the glycerin is stable.

I remember you saying once that 100% glycerin makes the purfling too soft to use, so I haven't tried that. Next time I may use 20%.

Not a good idea to use methylene blue to preserve the mix longer, eh? Smile

cheers,

If you want to preserve it I recommend phenol, but why bother?

I mix about a shot at a time, and do quite a few strips of purfling all at once, then throw the rest, such as it is, out. I lay all the purfling on my bench, brush on the mix, wait a few seconds, pick it all up and dry it off, and bind it in a bundle. It doesn't need to be soaked or anything like that--a little goes a long way.

The glycerin is a great idea. Michael, perhaps this is a foolish question but How well does glycerin work with lining and ribs, particularly the C's?

Thank you.

I have not tried it on them.

My guess would be that we would not like what it does to wood that's tonally important. It makes the purfling feel really soft, and I don't look for that in tone wood. Maybe on ribs it would be OK, but I'm not going to be the one to try it. :-)

That sounds logical.

That it helps bending the purfling is a great improvement in itself. I am going to try it on my next instrument's purfling. Thank you again.

Here are some photos from the show:

There were about 80 makers there, and about 800 people came to the show, over the two days. Lots of good contacts, but no sales. Good weekend all around.

Hey Chet, thanks for the update on the show. Looks like it's getting to be a good size. Nice table presentation.
Hope some of the contacts you made pan out to sales.

Joe

Good to see you there, Chet.

I've finally managed to get a few photos up myself, and have them in a Flickr album.

It was a good, and educational, trip.

Cheers,

Ken
