There are things in this realm that deify explanation, and understanding of them is only proportional to the time well spent, in the path of their pursuit. A quick glance in the direction of the image, is not to be the whole truth. I try not to deceive my self with knowledge hastily attained. Often if things aren't simple and readily understandable, it is easy to label it with some foolish name,, labeling it a fool. I must confess that during my instruction, I did not to participate in the consumption of the magic mushrooms, and that I also did not recite the special incantations flawlessly.

Anders Buen Posted February 16 Report Share Posted February 16 16 hours ago, Carl Stross said: How much can you tell about a car's engine by listening to the exhaust ? Same "system". Quite a lot, I think. You'll hear if it has a compressor, turbo, or not. Its number of pistons, if its a car or motorbike, if its a german or american car, diesel or petrol. If it is a high revolve engine (F1, or some japanese motorbikes) a Harlely or not, Italian two cylinder high torque motorbike. They are designed to sound different and its a part of the concept, especially for high perfomanace cars. This is taught in universities and some get their bread and butter from working on this. There is a bit of similarity between brass instrument sound generation and some car exhaust systems. An extreme example is japanese pipe cars with their "brazzy" sharp sounds, a "street made" thing. I think we rely quite a bit on acoustical clues from the car while driving. In particular in races. You'd loose a lot of information not being able to hear the engine, especially if driving a manual transmission car. Listening to high volume music makes you a less good driver.

But I follow american muscle cars on facebook and sometimes seek info on other types too. Not so much in real, but on the net, youtube or the like. Good repairmen rely heavily on their ears, even in direct contact with the engine through a large screwdriver some or smething similar. many will also listen to the engine above it for clues on the "health" of the valves.

That is all very true. I think I can hear valve lifters and keepers rattling or a dubious bearing, a piston slap etc. The usual. But from the other end of the car, ear next to the exhaust, I can't tell much. Maybe I can tell if it's an odd or even crank but that's about it.

Michael Darnton Posted February 16 Report Share Posted February 16 I was just looking at Carl's post history. I can think of quite a few people who are more irrelevant than he is, and they're remarkably persistent about it regarding noise v signal, and THAT is genuinely boring. If we are naming and shaming let's start a list. Wait, they do serve a value: when they finally show up it's certain that a thread has jumped the shark.

Of the over 8000 posts made by Carl any idea what percentage are actually contain working content? Have you ever actually learned anything from Carl? … anything? … don’t want to get into naming and shaming here for sure , and Granted a lot of folks don’t actually share things like specific varnish recipes wood quality ect and the like and post a lot , David B being a prime example, however due to wide , or narrow , range of direct experience such as actually making and winning…. Judging … having a wait list … I’ll gladly listen to a series of very pointed questions concerning subjects such as plate tuning over the seemingly constant objections distractions and dismissal of some one with virtually no real life experience in the field of violin making… the focus of this forum .

jezzupe Posted February 16 Report Share Posted February 16 21 hours ago, David Burgess said: Do all drums sound the same? Why do you think that an interest in frequency response is unhealthy, and why do you equate it with "plate tuning", since that moniker is most typically associated with the lower modes of free plates, not a completed violin? No, of course not David, just like when I turn over various violins and start using them as bongo's, tapping the back, they all sound different, but we're not supposed to play them like bongos , are we? or did I miss the memo that day? ....furthermore, does playing a violin back like bongos tell us anything about the quality of tone that it will produce when played as intended with a bow?....again I've yet to find any correlation that is worth the time of incorporating "tapping" things, much more concerned with "other things" that do seem to matter, like material characteristics, weight and dimensions, but hey man...maybe we could tune in and drop out and form a new society where we have daily drum circles using violins as bongos , we could all snap our fingers and do spoken word recitals and say things like "groovy" Quote Link to comment Share on other sites More sharing options...
uncle duke Posted February 16 Report Share Posted February 16 While thinning interior of belly plate #3 it bottoms out m5 wise lower than the first two - same billet, same thicknesses. So............. 2 hrs. later plate 4 rings lower than 3. Must be the tree. Quote Link to comment Share on other sites More sharing options...

Maybe. Many years ago, we invited a bunch of people to present at Oberlin, all with multiple VSA tone awards. Almost all of them incorporated some kind of tapping and listening into their making strategy. This isn't to say that I'm sold on it. Only that the evidence suggests that it should not be summarily pooh-poohed. 52 minutes ago, jezzupe said: but hey man...maybe we could tune in and drop out and form a new society where we have daily drum circles using violins as bongos , we could all snap our fingers and do spoken word recitals and say things like "groovy" Sorry, man, my first visit to Haight-Ashbury (maybe around 1970?) was shortly after all the "groovy" stuff had already gone away, replaced by people in suits n stuff. But back home in Seattle (which was several years behind San Francisco in hippedness), Owsley was still a famous name. Quote Link to comment Share on other sites More sharing options...
Marty Kasprzyk Posted February 16 Report Share Posted February 16 It might help to define what "plate tuning" is. It is usually assciated with thinning the top and back plates and is used: 1. to hit various mode (usually 1,2,&5) frequency targets. 2. to hit a plate stiffness target S from mode frequency F and mass measurements M. S=MF^2 3. to hit a plate impedance target Z from F and M. Z=MF 4. to give something to argue about if above 1,2,3 is helpful is helpful or not.

Dang, you've gobsmacked me once again! I will readily acknowledge your experience with some contemporary makers in Chicago, if you will acknowledge my experience with contemporary makers all over the world, and separately, that the Oberlin Violin Making Workshop routinely has makers from all over the world, with many different backgrounds and training. Deal? Quote Link to comment Share on other sites More sharing options...
