  1. I guess there’s lot,s of ways to filter air , ..... I have several, a big one, one that blows and sucks huge amounts of air , a small one for benchtop, and a supper fine one with charcoal, as well as a laminar flow hood for varnish, my personal favorite is the benchtop unit that can be moved wherever needed, helps keep the dust where I want it ,before being distributed , ...so currently..... last year or so, I,m slow... I am setting up a varnish clean room, and this discussion does raise a question , on mounting height , I always see ceiling mounted air cleaners , but this seems counterintuitive, is it just to get the unit out of the way? Dust is heavy and settles on the floor, benches ,so every step kicks some more up, maybe it makes more sense to go low?
  2. My major concern of elevation would be more moisture related vs elevation , I,d expect over all drier conditions at seven thousand feet vs 1500 , or sea level.
  3. One trick I use is to slightly compress the purfling after the dry fit , a simple round rod of wood will do the trick , like rolling a pie crust. Not enough to crush the purfling, but just move it a bit.The glue or hot water then swells the purfling. Also I will size the channel ,as the top channel especially will swell with glue, after the channel is dry, simple to go around and fit the Purfling. As for marker, one can grind a offset angle, bevel to move the edge center one way or another, if a person is careful, very little shimming between the blades is needed.
  4. My bad for not reading the whole thread, ....
  5. Here,s a possible method ,,,, if one were to for instance cover the surface with some material, close fitting like a cloth or foil maybe a paper dampened, , then to cut an accurate outline ...for holes what not , one could simply weigh the materials and compare to a known weight for x sq inches , might take a bit of trials , and testing, but in theory, should work.
  6. Never understood the fiber...paper... purfling thing ...,probably best for production work, did use it on my very first. Under a magnifying lens it,s incredibly boring, but from 40 feet ...does the trick.
  7. Always had great service with them.
  8. Here’s a shot of my homemade bushing maker. Super simple , nylon shafting drilled and reamed , I use brown paper bag, cut in a arc, soak in hot hide glue for a few seconds, twist one up and slip it into the counter form , just need to let it sit a few minutes to let the glue set , then pull it out and off the mandrel for drying. Works a charm. I have a few counter forms , of larger sand smaller dia. So I can make a variety of sizes. Pre test before glued, I can adjust the paper length to just fit .
  9. Yes...don,t know the text dates.or location to cite, but. ....it,s out there...maybe this guy? Andre' Jacob Roubo?
  10. I,d say most likely , and yes diluted with water helps.
  11. Same as others here, from the Roubo text, some add ash , some not. The only major difference is that I use a nicely sized plant Pot..over a five gallon bucket..to hold the mix, ...instead of the bucket with holes...lol ... nothing fancy with the alcohol, though I Don,t think it would hurt at all, just a triple filter with paper coffee filters and boom ! bobs someone’s uncle. ...I like it for several reasons , mostly it has a complex coloration I find appealing, while still allowing the wood to show.
  12. Pop filler, Horse sauce w, wood ash and cooked rosin varnish applied thin
  13. I concur, depending on available tooling though,a fellow could cut outside the line and file or sand to final shape.
  14. I'd say we all are ..... lol.... value is hard to ascribe, do we value the name ? The look the tone? Resale ? How about hourly and materials.? Of course big picture stuff like awards and high profile players help sales, .....varnish and set up , ? My honest question becomes what are people valuing as they consider the purchase of a contemporary violin. .?
  15. Don, have you looked into any sort of scanning probe ? With one a guy could hand carve what one desired,pop it in the machine, then scan or probe into the GCode , ready for what would seem to be simple edits to the program for margin and what ever small changes might be desired. They even have hand held laser scanners and ones that work with rotation available. But to my mind the touch probes seem more cost effective. ....nice work.
  16. I second Jim’s suggestion , I will not be able to be there this year ,wish I could,, got a job doing iron works on a deadline, but after attending two years, IMHO Joe,s got a pretty good handle on Del Gesu model , shares openly , friendly fun and honest, with great hosts and dedicated students. In terms of models and style, remember early works were marked by more or less clean work,comparing favorably to strad and others. it,s the latter years when he started going wild. Another bit to share is that his corner overhangs were generally more than the 2.5 /3 mm we are used to in modern work and the plates do not exactly follow the rib lines up to maybe 5-6mm , leaving them somewhat fragile. ....
  17. Aluminum might be a option, because it requires so much energy to smelt from ore, at one time it was more expensive than gold.
  18. Thanks Jim! the blade is San Mi laminate, wrought iron and 1095, handle is navel bronze ,deer antler , oak burl, the shifty was fun, made of the same oak burl and reindeer leather .made for my daughter, the youngest in Colorado, she wanted mountains, ...she got mountains.
  19. Probably mostly chips, like fiddle making...lol...been making some knives lately, so lots of handles , maybe a slab through the middle for a table , a few bowls,....
  20. As art goes, like is a whole lot more than the swimming with cello..... from a craft standpoint, the article says nothing of what sort of resin...west system ? Curious minds think curious thoughts.
  21. Sorry for the delay responding, busy busy days. The burl is now fully power washed , safely ensconced in a thick layer of wax , in the shade , in a cool dry place, , with plenty of fresh air awaiting a trip to the band saw mill . Anchor seal ordered. Cut plan ....under consideration.lucky for me it rarely gets over 60 f here, some times 65.... and humidity seldom drops below 50% .... so good lord willing and the creek don,t rise , should be able to send a chunk out you way in a fort night or four .... or seven ...or .... thanks gentlemen.
  22. Just because there are so many more good minds here, gotta ask . So...Scored a big,... 40 inch root ball cherry burl. It,s amazing, no rot , no bark inclusions, pretty much a perfect whole stump ...don,t want to mess it up, right now it,s sitting on a trailer with most the bark power washed off , tried to do some research on best practice with this wood, not a lot of info except to seal the ends. Cure in open air and shade. Wondering if I should make a few stress relief cuts along some natural fault lines or leave it alone....any advice greatly appreciated. We can also talk about wood curing in general , any neat or cool tricks, just mostly interested in getting the best from this stump.thanks.
  23. Define better.... on one hand it must be secure and accurate, on the other it needs to be repairable. There is no standard angle because plate height and overstand varies a bit maker to maker, any sort of a shoulder or through neck type joint will be rather set, in it,s angles making minor adjustments of center to center, overstand, projection to bridge difficult to impossible , the current low angle , shoulderless dovetail, fits all the requirements . Secure, accurate, and repairable.
  24. Well well, happy birthday, wish you many more,health wealth and friends by the score, Thanks for sharing.....I think.
  25. Condolences to his family, fun and intelligent, will be missed for sure. Love the life he shared.
