Hi David, Tim and all: Woops, that was a generalized statement about starting from scratch and not about plate tuning. I've followed your progress and take my hat off to you for your work. ............ David, I know nothing about a piezo strips nor know why they would be better? The phono can be adjusted down to less than 1 gram or up 10 grams for I don't have a tracking or skat

Don't forget to get a good fit at the bridge feet. cheers edi Haaay, let's not get carried away with turnbuckles, toggles and marine eye's. :-) Actually I see no reason these cannot be fitted to your plywood calipers. ............. Was looking at mm dial indicators and found mention that the indicator stylus is 4-48 thread so that may be an international standard just like ball bearings are in inch sizes.

    quote: Originally posted by: edi malinaric Hi GTM - I should have put these up before you started making shavings. This one works a treat for tracing the plate contours. ... The little drop of nail polish on the setscrew is useful when tracing the contours. Adjust it by 1 turn and you have the next contour exactly 1mm higher or lower. Half a turn gives you a 1/2mm difference. Makes beautifully even contours and picks out the high/low spots beautifully. cheers edi Hi edi and all: No shavings yet, probably a week away at the rate I'm progressing. That's slick, I like

I'm about 90% complete with the Plexi caliper. Actually it's working fine but there is 0.005" of flex when I apply a bit of pressure beyond that of the dial spring. The arms ended up being 1.5 wide and the throat is 9.25 deep to the dial center. I can shorten the arms for it was an arbitrary length based on the original plastic size.

  8. Bad news of sorts. The "100% pure tung (china oil) oil I received from Leevalley apparently has had the UV catalyst properties removed. The first coat allowed to dry for 12 overnight showed no hardening change after 1 hour in the sun, a 2nd hour with same results. After 48 hours it still was still soft enough to load up 220 sandpaper. When I tried the white steel wool synthetic pads equal to 0000 it picked up slivers at 48 hours. At 60 hours I was able to get a second coat which was exposed to the sun for one hour, 9 hours later it could take another coat if I did not sand. There are s
  9. quote: Originally posted by: Andres Sender You might want to read Keith Hill on area-tuning the violin, I believe some or all of his articles are now on the web.

  10. Hi all: Watching TV show "How it's Made" for steel drums and noted the tuning process and was thinking of various possible methods of attempting same for violin. In the case of the steel drums they had microphone(s) / pickups used though they seemingly kept that info secret. They did mention it was being fed into a computer/laptop but again nothing shown. I was under the impression that it was not sophisticated or beyond the average pocketbook. I have seen colloids used to visually display a sound/ pattern though don't know that a specific frequency was assignable. Using glitter mig
  11. Here are a few of violin and first coat of tung oil on cigar box. Was late night and no power sanding. Daylight will expose to sun and hopefully have more coats and high speed orbital sander. I'm interested to see how it will fill in what appears to be fairly porous wood and how many coats it will take. http://home-and-garden.webshot...album/562839445EXdweX Cheers, gtm

  13. quote: Originally posted by: Jacob Very well, I'm not about to question the merits of your case. What I'm questioning is you sniping at the guy on an Internet forum from behind a "user name". To me that's terrorism. Either pursue your case via legal channels or shut up, and live and learn without involving the rest of the world in the process. When you get burned by someone big time you may take another stance. However, I see no relationship to terrorism. How else is someone to learn of a business person's character if all that is offered are glowing testimonials when there
