  1. I use Japanese scraper planes, flat bottom with wood bodies, the larger one i use on cello and bass fingerboards or to remove larger amounts of wood, the smaller one is for finish surface prior to sandpaper used with a stiff block. larger plane is 170mm x 60mm with a 45mm blade small is `100mm x 30mm with a 23mm wide blade when the smaller is adjusted just right the camber is right when it stops cutting, then ready for final sandpaper and polishing. i use a leather backed block of wood for sanding block, 150mm long, this cuts the planing marks without following the differences in grain density and planeing chatter reese
  2. Ken more of a problem in live wood with active moisture in the cells - fungus feeds off the material in the cells, once dry should only be a visual problem, if the wood is really dry and stays that way using it probably not a problem especially for linings. reese

  4. wood like maple get a variety of fungal stains - one of which is called "purple stain", considered a defect in the wood industry and caused by exposure of the wood to moisture - like stacked under a ton of steel bars, might be possible to cut it out or work around it but it is likely to spread upon further exposure to moisture and possibly air. reese

  6. well the horse hail does have scales which lay overlapping to the tip but I have seen a study that showed that these are rubbed off very quickly with the first rosining and then the rosin crystals are embedded into the softer core of the hair, the article was in either scientific american or smithsonian magazine in the 1980's sometime, wish i made a copy, Reese
  7. currently trying aquila .72 but the idea about beef gut was raised, first conversation with Dan Larson the player had wasn't promising but I have him calling back plus other sources to see if any of the makers have any ideas - its his project at the moment. he is waiting on a new shipment of aquila strings to see if the revised knot will work on a new string. thanks for the help, let you know results Reese
  8. ya, just wish he had opted for a small 7/8 cello and for 6,500 he spent alot for a pig in a poke
  9. apparently Dan did not have an option when the owner called him the first time - string length is the big issue.
  10. Hi everyone Just spent a frustration hour with a new client and his new five string baroque cello, he had it shipped to him and when attempting to bring it up to pitch (415) the gut e string kept breaking. The first portion of the visit was smoothing possible sharp edges at the tailpiece and devising the right size of the loop tying it to the tailpiece. the string was ok at the nut and pegbox but it was getting shorter by the attempt. so much so that I ended up having to tie a extension to it to get enough length to wind around the peg shaft. finally was able to bring up to pitch for a sound check for the soundpost position but just as he did a final tuning for stretch the string exploded right in the middle of the string - no sharp edges involved just a weak point in the string. since he was down to last string at that point it brought the session to a halt until new ones arrive - at least we determined the right knot and loop to use and then got down to finding out the root cause of the issue - size of the cello. the owner had ordered a copy of the big Strad model (body length of 790mm) assuming the big body means big sound and the makers (chinese) but on a neck wide enough for the five strings which means also a very thick heavy wedge shape but also made it proportional to the body for a string length of 715mm. the result being, unless the can find a string maker with a miracle e strings, that there is no possible way for a e string to work at a415. the tension is just too much. His next step is to call around for a miracle string and failing that he has two options (unless any of you have a third option) - revise the set up and use it a a normal four string baroque cello or try revising the set up with a false nut, moving bridge position to reduce the string length to 690 or less and then tune to lower a pitch then it might and i think might work. The other five string I have worked on was able to work because it was shorter string length with a395 tuning. He just has too big of a cello for a five string - interesting that Cathy Caldwell's book list her collection's five string cello as having a similar problem even with a 709mm body and a 644mm string length any ideas?? reese
  11. Conner's solution is what I would do as well with just the additional note to use a pan head screw instead of a wood screw. reese the shaft above the crack should be just larger than the screw diameter so the two sections are pulled together otherwise they will work apart over time.
  12. I have worked on a couple - a collector in Erie has them, main problem was the pegs fir into rubber gaskets. The new plantary geared pegs solved that,The neck has a wood insert bolted into place and a normal ebony fingerboard glued onto that. all in all a strange duck. There are tales told of using the basses as boats in the lake at interlocken michigan Reese
  13. Hi Richard, thanks for the link, that is it exactly, interesting that it appears on so many models Martin, I agree with your dollar figures, just used the last document's number in my post which means the guy doing it hedged his bets and didn't want to commit either way without really saying it. This person is known for inflated numbers and his fee based on percentage of that.
  14. Rick I may have to needle point that to hang in my shop, it brought tears to my eyes and a memory trip back to my Woodstock days. And Jacob, it is my opinion that the large cross grain cleats do more damage in the long run, I can't count the times I have been faced with the new cracks running up the edge of the old cleats - or find buzzes from loose ones if I feel the need to reinforce I opt for a diamond shape with the grain on the bias and the long axis aligned with the crack.

  15. yes, you are all echoing my own thoughts, I could see it was hinkie but I am faced with having to explain that to a nice elderly lady with limited english that her family treasure is not nearly as valuable as all of her stacks of papers indicate, they are sure it is a real joseph klotz and while that would be worth the 6k, this violin isn't worth near that and it is up to me to break the news and try to sell it. I do think it will be a nice violin for a new owner but I was hoping to get some infomation to use as backup when i let her down. the inside is better than the scroll would indicate - nice linings, good corners but i will not be opening it, perhaps it was "cleaned up" when the crack in the upper bass bout was fixed. reese I was hoping beyond hope that that brand was recognizable
