  1. Hi All - I'm thrilled that the clip resonated so well among us "micro-woodworkers". Bengreen - I would have given my eyeteeth to have had the opportunity to study aeronautical engineering. However in 1957 there was no such course available in South Africa. If it hadn't been for the generosity of a family friend I would never have had the chance of becoming a Mechanical Engineer - so going overseas was out of the question. In my turn I have passed on that act of generosity by sponsoring several of my technicians to further their studies. It's tremendously satisfying when one of them grabs the opportunity and "flies" Brad - the balancing would have taken place in the next stage. Usually by adding extra coats of dope as required cheers edi.
  2. Hi All - Ten years ago I was part of a violin making class. Over the 5 years I noticed how often the various class members would agonise over those various steps mentioned in the title of this post. I came across this youtube clip and I thought that I would offer it up for your enjoyment. cheers edi

    Hi David - welcome. Nice cello too. How does it play? I'd also go with poplar for the back. Interesting... - almost no channel at the c-bouts - seen that on some Russian instruments - but then very flat plates - or is that from the camera? I might lean towards a JTL - except the condition is far too nice. enjoy. cheers edi

    Violin neck heel angle?

    Hi Jim - there's much to be said for gluing on the top plate first. cheers edi

    File question

    I find it amazing that it still works. I have some 80/90 year old files from my Dad - not much use - mainly sentiment and raw material. cheers edi

    Opening a Seam or Crack

    Hi Jerry - funny that you mention that. Yachts and sailing dinghies require the occasional re-spray. Cleaning the spray gun requires the use of considerable quantities of MEK solvent. There's nothing wrong with it other than the residue of the twin pack polyurethane paint. So I built a still to recover the solvent. Simple thing to make - 1.0 SCHEDULE OF QUANTITIES - a 1200mm length of 12mm dia copper water pipe - a 1000mm length of 22mm dia copper pipe - two 100mm lengths of 12mm dia copper water pipe - two 30mm lengths of 12mm copper water pipe - two 22x22x22 tees - four 22x12 reducers - two 12mm dia bends - one 1 metal can with a metal screw-on lid (I use one of the tins that holds the activator half of the paint. You always seem to collecting nice clean replacements.) - two lengths of plastic water hose - a hose end-fitting to screw the hose onto the nearest tap - three 12mm hose clamps - two 22mm holderbatts - one hot air gun ASSEMBLY - Solder all the copper bits together in the correct sequence - solder the 12mm pipe into the lid of the evaporator tin - connect the water supply and drain pipes OPERATION - half fill the evaporator tin with dirty solvent, - screw it onto the lid - heat with hot air gun - collect clean solvent. COMMENT The only half-tricky operation in the job was to drill out the 22x12 reducer so that the 12mm dia pipe would slide through. It took less time to assemble than it took me to slip down to the local hardware store and buy all the components. MAINTENANCE Nil LIFE EXPECTANCY Unknown - 32 years and still in use. Test on-going. cheers edi

    Opening a Seam or Crack

    Hi All - what happens is that if the alcohol is pure enough (very low water content) its affinity for water removes the "water of crystallization" from the hide glue (i.e. it dehydrates the glue) - making it super brittle. Get "pure" alcohol from the chemist. The upper limit is about 95% alcohol - its next to impossible to remove that last 5% of water. Use a syringe to remove about 3ml from the original jar and refit the lid immediately. Doing this will prevent the alcohol going on a "water-binge' and eventually losing its potency as a dehydrating agent.! After you have slipped in your opening knife, spatula and have the glue under stress, carefully place a single drop on your opening knife and twist the instrument to guide the flow down into the crack towards the glue-line. Resist the temptation to flood the line - that way only results in a waste of alcohol - the scene of action is the stressed hairline-thickness of the glue join nearest the knife blade. Remember your youth - an excess of alcohol makes a poor companion. After running the single drop into the opening repeat the following mantra at least 10 times before adding another drop. "I must give it time to work. I must not hurry this process" - repeat, repeat repeat. [In particularly stubborn cases I find it helpful to add a brace of Hail Marys - for Cellos replace with "Our Father"] :-) Success is signaled by a sharp "crack" as the the glue line parts and the loosening of the "pinch" on the knife blade. Gently work the blade forward - stressing the glue line once more and feed in another drop of alcohol. Off course if it isn't hide glue all bets are off. cheers edi

    First build plans

    Hi MSmartt - The "smarttest " step you could do is to find a friendly violinmaker and "bribe" him to allow you to work under his supervision. Your biggest difficulty will be to understand what he is talking about. I was supremely fortunate to have Brian Lisus - http://lisusviolins.com/ - guide me along the straight and narrow of the art for 5 years. He's based in Ojai California now - so if you are close....

    Hi Manfio - next year I'll celebrate my 80th birthday - please send my regards to your friendly Japanese machinist. We both come from an age when broken things were repaired - and - "better than new" was our credo. cheers edi

    Hi Muswell - well ... the f-hole is wide enough :-) cheers edi
