  1. Bill is joking (sarcasm) using some disagreements and rather long winded threads from this forum as material.. This forum is non-commercial. Read a bit and I think you'll find a good number of pros share knowledge and recommend colleagues. Many of us know each other outside the Maestronet world (teach together, collaborate, do business together, meet at conferences, enjoy each others company). Welcome to the forum. Please give my best to Ute and Larry.
  2. Flaming: An online argument that becomes nasty or derisive, where insulting a party to the discussion takes precedence over the objective merits of one side or another. Bullocks yourself, "Mr Tell"
  3. Hi Jacob. No killjoy. All good observations. Concerning the jig I illustrated (Brad already spoke to his): As I said: This system works well for me. If it doesn't make sense to you, do what does. I do believe a more-or-less universal jig could be fashioned, though I've never had the desire to do so... some rectangular board with rows of pin holes or something similar, but it doesn't take long to fashion a custom jig when needed. There are a variety of ways to ensure the alignment of the crack in the jig which I won't go into at the moment, as if you read my description of the process in this case, the crack was left dry (no glue) in the center, and the purpose of the jig was to align the ends at the edges (as the broken piece "sprung" after the impact released it and was actually slightly longer than it originally was). The middle portion aligned very well dry, but in this case I did not risk it remaining that way in the jig with slippery glue applied. The center of the crack was glued in sections using pillars and wedges (good for signing the crack correctly as well as adjusting thew arch to it's original contour). I tend not to use pressure from above or below the plate for alignment unless really necessary. A slight gully (caused by the wood swelling from moisture, then shrinking back) sometimes results if the clamp is not removed quickly enough. The clamping wedges in the jig were numbered and pre-marked for position. Clamping was very quickly accomplished as only the part broken away was "free". I'd say it was at least as fast as messing with a bar clamp. Since the perimeter was glued down to the jig platform, and the free piece was held by the cams & wedges, no arch deformation occurred. The crack was well aligned after gluing. Touch up, with the exception of the small flakes of wood and varnish that were missing when I received the instrument, was very straight forward and did not require any the the existing varnish to be altered at the boarders of the crack.
  4. As clean as they get, except for some small bits of chipped out wood at the surface. I was a hard impact.
  5. The quote above refers to top cracks which I've also used variations of the jig for... but I'm assuming your asking about the one I illustrated? The violin illustrated, made in 2005 by a friend and colleague with a rather good reputation, was dropped onto a CIM studio floor from a standing position in 2006. He, the owner and the teacher asked me to repair it.
  6. I haven't found this to be a problem, Nate. When appropriate (as in the situation above), I find that performing partial, or staged, gluing improves the alignment (and therefore the glue surface contact). I don't see this as non-homogenous. Of course it's important to make sure the glue gets into the crack as evenly as possible, but working time can be reduced if doing a smaller area... and therefore a dilute (thinned) form of a stronger gram strength glue can be used (which I see as pretty much of "a wash" in terms of bond strength). It's pretty easy to tell where the glue "runs" and where it stops when pumping the glue by plate manipulation or use of a suction cup. Cleating as you go can ensure that you don't weaken the previously glued portion when manipulating the next...and that you get the glue to run in to meet the last section successfully. I also don't see cleats as holding things together as much as stabilizing the flex of the plate in the crack area. If a crack is going to open, it often seems to do so even when cleats are present.
  7. An alternative to consider: This kind of setup works well for me. I've used it for repairs to the top (similar damage as illustrated in Brad's photos) as well, but the photos of the type of jig I have handy are for the repair of a back where one of the flanks broke away. In this case I used the jig to align the outer ends of the crack (matching the purfling lines) as the fractured "sprung" a bit after it broke away. I glued those two areas in the jig, then did fine adjustments to the center of the crack using pillars & wedges. For less obstinate cracks, I've used the jig to glue in one go. The larger portion of the plate is glued down to the jig around the perimeter with paper squares (so it can be easily removed). Hope this helps.
  8. Yup. I tend to agree with just about every word... and I've sometimes managed to successfully navigate misplaced anger from clients when it occurs, but only with polite patience and great effort.
  9. Honestly, I believe the reason you received no response is that there isn't a an answer to your question... except maybe photoshop? The cracks need to be re-repaired.
  10. By definition of the word I'm used to seeing, I believe the only portion of the piece that would be a forgery would be the label itself. The act of inserting a label with intent to deceive would be fraud or a sham, not forgery.
  11. I don't know why the homepage lists the spammers posts... software is not my thing... but the spam titles seem to be dropping off the list as they work their way down the list. I believe there are 5 left as of today. The one I caught this morning disappeared from the homage as soon as I classified it as spam. Please also note that if you click on a spam message on the homepage list, it takes you to a page that says the content is not found. I honestly don't visit the homepage, so I've only noticed this after this thread appeared.
  12. I think Peter is the Svengali of the local violin making community! Good thing he uses his powers for good and not evil!
