  1. Some of you may remember me and my unique bridge designs - violinbridgeworks.net. Now I'm considering moving on to the violin (and other stringed instruments) body with an innovative design idea. An idea that would control movement of the wood in a similar way that is used to control the passage of light through the crystals of an LCD screen. I'll be back later with some of the details of the project.

  3. quote: Originally posted by: NewNewbie Nice shop n' bandsaw tim2. Did you post this under shop pics as well? Quite likely - the picture is a year or two old, but that thread is too long for me to go have a look at to find out. Since that picture was taken, that large slab of maple on the table saw has been diced up and pieces of it are at different places all over the country, the parchment stretched and pinned near the middle of the picture, too, has been cut up and distributed, the splits of sycamore back in the right corner have diminished, I ripped out the old workbench to the right and completely rebuilt it, the stack of particle board and veneer plywood is in part, the top of my new workbench, many of the flutes in the box over in the lower right-hand corner below the workbench have been finished and sold, the sawdust in the dust collector bag has been filled and emptied numerous times, the tung oil cooking in the pressure cooker on the small stove near the back is ready for use, the bucket near the bandsaw containing the discards from bridge blanks has been emptied and refilled a couple of times, and the shop is now riddled with parafanalia related to the making of slide rules for kids - my most recent endeavor.
  4. quote: Originally posted by: NewNewbie This page has the Timberwolf bandsaw blades that run on a lower tension, that saves wear n' tear on your saw and the blade lasts ( is suppose to ) longer.... I too really like the Timberwolf blades. I use them exclusively for general purpose. For a practically perfect finish when resawing (even paper-thin) I use the wood-slicer blades. I have a rather large Jet bandsaw shown in the middle of my shop at the link below http://2timv.com/miscPics/ShopPicBig.jpg I had the exact same problem as Seth. The guide below the table had become misaligned, was touching the blade, wearing the teeth on that side and causing a crooked cut. This saw has rollers for guides, but below the table is an additional guide that the blade goes through but doesn't really touch, and it is the one that was out of alignment.
  5. quote: Originally posted by: David Burgess "tim2", a bridge cut the way you describe would be end grain on the front and back surfaces. While this may be viable, it's not he way bridges are usually cut. Normally, end grain is on the sides of the bridge. Hi David, Did he really write "parallel to the ground"? I'm sure that he knew better, and was right about the coffee thing - Tim
  6. quote: Originally posted by: GMM22 Imagine cutting a slot in a tree trunk parallel to the ground with a saw. Now imagine that you take a bridge blank and try to hammer it into the slot as a wedge, but because you decided to do this before having your morning coffee, you hammer it in feet first. The way you describe, is the way my bridges are cut - opposite the cello bridge shown inside the log at the link provided. And yes, as you suggest, there is less yield. For final cut, I suggest that the side with the rays face away from the player. If a bridge were cut as shown at the link, I would suggest final cut with rays facing towards the player.
  7. I'm one who enjoys reading the things that GMM22 writes about. Tim
  8. If you're interested in film, a place to get the smallest quantity, inexpensively is: HERE You could also remove the elements from one of the piezo products sold at radio shack, but the resonant frequency may be near what you may want to analyze, so be sure to read the specs on the package before you buy. If you're looking for accelerometers, the ADXL202E is pretty good and easily found with google. I just found out that analog devices has a new one that's better and even a smaller package - the ADXL330. I read somewhere that they may be coming out with yet another one that's about the same technology but a little smaller yet.
  9. I sell parchment. Not made from leather, but rather animal gut. It's very thin, quite strong, and of course attaches easily with hide glue. Some pictures of strips for bridges as well as large pieces at links below: large piece strip My email is in my profile.
  10. I always enjoy reading your philosophical input Dean. I seem to recall you mentioning that you are a writer. If not, you really should be. I also always enjoy reading articles like those written by Alan. I'm sure that all of us - most likely because we all share a passion for the violin - have similar sentiments. I find myself lost in time whenever I encounter things from the past that have special meaning and connection with things I'm involved in now. Being a fly-fisherman it's a special moment when I encounter a very old rod and reel as well as the old hand-tied flies and creel that go along with them. Being involved with archery and guns I love the old guns and longbows. Having a passion for photography it's a thrill to encounter old cameras, or black and white photographs. Having been involved with many aspects of working with cars, being around the old ones transport me to a time when that's all there was. I've always had a passion for books and have recently been involved in the old ways of book-binding. Holding an old tool in my hand causes me to long for a time when there were no power tools. Like yourself, I too have a rather large collection of old vinyl which I very much enjoy. There was a time when I was frustrated and even found myself angry by the way things change. I was definitely not one to embrace technology. But whether I embrace it or not, it's here, and always will be, so I've learned to accept it and have even learned to appreciate it. In fact, at this point in my life, perhaps more than ever, I have a deep sense of appreciation for the here-and-now and am just as excited thinking about what is to come, as I am thinking about what has gone. You're right - it's about connections.
  11. David - I've enjoyed following this. Thanks for conducting the experiments and for sharing the results.
  12. Interesting article. I think many people are frustrated by innovation and change. It's interesting to see an article, on a web page selling violins, against innovation concerning the violin - the internet is an icon of innovation. Imagining someone sitting at a bench for hours carving away to make a violin, and then using the internet which is all about doing things quickly and getting one's information handed to them on a silver platter, to me, demonstrates how confusing things are these days. It's complicated, where the craftsmanship actually lies these days. Is it the ability to copy the work of another craftsman, or is it the ability to create something innovative and new? Should one be more admired for their craft if they create something using methods that have been used in the past, which at that time in the past were innovative and new, or by methods, that like their craft, too are innovative and new?
  13. quote: Originally posted by: Jeffrey Holmes It's funny... but it seems that as soon as I feel settled, I change my mind/style slightly. Jeffrey, That bridge looks very nice. The only thing about it that I find a little distracting, is the angle of the cut at the end of the heel. Being at the same angle as the cut of the toe, it makes it look to me like the feet want to slide away from each other which just makes it "look" weak even though it's not.
  14. quote: Originally posted by: Michael Darnton This is something I cut for a rental cello (that is, it's beefy, and a bit quick/rough) but the lines are essentially what I usually do: That's very nice for a rental cello. I very much like the way you do the feet. The inside angle of the heel flows with the upper curve of the embelishment at the knee, and the toes are an appropriate length, with the tips cut to an angle that flows with the angle of the thigh. Some of those angles do nothing for the functionality, so it's nice to see a bridge where someone makes the cuts of such things in a way that lines of the entire bridge flow in a nice way. Tim
  15. quote: Originally posted by: scratchy rosin I downloaded a trial period of the Topaz plugin for Photoshop Elements. From here Topaz Plugin This is a first attempt but there are many other options to try. That's one of the best I've seen!
  16. quote: Originally posted by: GMM22 One last note: Stories of early childhood folly with dangerous elements are just a disservice. If human history was not dotted with unspeakable suffering due to lead and heavy metal poisoning you might have a point. I would not want the burden of knowing that I might have encouraged someone to do something stupid like play with mercury. But then again, someone once said that there are only two infinities, the Universe and human stupidity. I disagree that writing about something done out of ignorance is a disservice. I would never encourage someone to do any of the things I've done out of ignorance. If anything it should encourage someone to give a second thought before doing something that may be considered a little unusual, or if nothing else pay close attention to what their kids may be doing - kids are likely to explore in many ways we never even think about.

  17. quote: Originally posted by: GMM22 John, Ultimately, to each his own, but the hazards of lead are well known and beyond dispute. . . I occassional wonder what lead related doom awaits me. Although I'm in really good health both mentally and physically I've had a lot of lead exposure in my lifetime. When I was a child of about 9 or 10 I had a kit to make lead soldiers. I made hundreds of them for myself and friends. I'd melt the lead, pour it into the moulds and then when I removed them I'd scrape the extra lead off the soldiers near where the two moulds joined as well as around the base, using my fingernails and sometimes even my teeth. Nobody gave any thought to it back then. As I grew older, I use to help my dad who was a plumber. We did a lot of drainage pipe using the old cast-iron bell-n-hub that required the joints to be packed with okum and then melted lead poured in and packed. I did that for a couple of years followed by a lot of water line replacement which of course involved a lot of soldering with the old style lead-based solder. Later in life I spent a couple of years painting heavy equipment in quarries with the notable yellow paint that was full of lead - never wearing a respirator unless I was spraying some of the alkyd enamel that was so sticky I couldn't get it out of my nose at the end of the day with the usual hard-blowing of the nose. Even later in life, I got involved in automobile restoration. A lot of people use plastic fillers these days, but I used only lead. A lot of the old bentleys and porsches a full of lead at the welded seems and around the edges, which had to be melted out before I did the repairs and then melted and paddled the new lead in. The new lead was filed with a vixen file so there wasn't much dust there, but after that I'd sand it before priming which produced a lot of very fine dust. I can't recall having ever actually putting lead in my mouth, chewing it and swallowing it. I wonder if I'm at risk. Of course I could add to all the lead exposure with a lot of exposure to asbestos when I was tearing into walls and ceilings to replace pipes, not to mention the asbestos pipe that I use to work with that was commonly used for water mains and drainage on the west coast. Not a lot of dust exposure there except when cutting with a chain type snap-cutter and some filing of the cuts before coupling. Back in elementary school I remember how cool my friends and I thought it was to remove the mercury from thermometers and play with it. We could gather into our palm and it would sort of meld together and then if dropped on a surface it would break into thousands of microscopic beads. It could also be rubbed on a coin to really make it shine. Like the lead, mercury wasn't given much thought back in those days. Top all that off with smoking 2-packs a day from about 15 years old to about 40, and sometimes I wonder if I have a few health related surprises awaiting me later in life. I'm 53 now, and like I said I feel really great - lots of racquetball, hiking, and other physical stuff with no problems, but I still wonder if something could be brewing in me that I don't yet know about.

  19. Hi Seth, It seems as if you're very proud of both your photography and the violin you've made. You deserve to be - the violin looks very nice and your photography is pretty exceptional as well. Although I've done quite a lot of photography, I've done very little of this kind so it's really nice to see the way others are doing it... thanks. I'm always looking around in photos and couldn't help but notice the bullnosing of the drywall corners in the house which looks very nice. Looks almost like synthetic counter-top as well, allowing for a smooth rounding of the edge which to me looks better than laminate. Tim
  20. quote: Originally posted by: ChrisBurt Tim, that hunk of wood in the foreground, is that a one piece back for anything in particular Chris, I haven't decided what I'm going to do with it yet. I got a pretty good deal on it and even though it's not all that bad, it's also not really all that terrific. Tim
  21. quote: Originally posted by: luthier9010 Oops last photo was suppose to be of this bench. Berl That's a pretty heavy-duty bench. I particularly like the heavy timber around the perimeter. My shop: small picture here large picture here It's just a "general purpose" woodshop. Tim

  23. quote: Originally posted by: Michael Darnton I still have a workspace and a storeroom in this space, which is on the 20th floor and has clear views south to the end of the earth, and east, over Lake Michigan . . . Awesome! Got any pictures of the views? Thanks, Tim
  24. Amori, I had once considered building a thickness sander and then made the decision to buy the one shown HERE. I couldn't really afford it, so I first went around and talked to friends and friends of friends who might have wood laying around that could use the kind of cleanup and smoothing that such a sander could do and after I had enough work lined up to help pay for it, I bought the sander and paid for it by doing the work. Because this particular sander is open at one end, it can do up to 36". There's rollers before and after the drum to hold the wood down, so wood can be sanded pretty close to paper-thin. I've cut american sycamore veneer up to 12" on my bandsaw and then run it through the sander for removing any marks left by the bandsaw. If you do end up making one, I hope you post some pictures as it sounds like a really interesting project! Tim
  25. Seth, I agree with others who said you can easily repair them since they aren't badly distorted by overcutting. Tim
