Aha, that sort of makes sense, you mean that softer pads have a certain amount of self levelling due to the cushioning? But I was under the impression that these type of gold pads (without the self levelling) have been around for several years anyway.However, their rigidity require them to be self-adjusting in order to work (or maybe just to be set up in a finite time). But that's mainly guess work from my part...
I can see how it would reduce reseating, and how the material itself might reduce rep adding, but I'm not sure the self levelling feature itself would reduce repadding?This has been a long time coming. A properly installed self-leveling pad would reduce a lot of repadding
Yes, that was what I meant.Aha, that sort of makes sense, you mean that softer pads have a certain amount of self levelling due to the cushioning? But I was under the impression that these type of gold pads (without the self levelling) have been around for several years anyway.
This isn't a new idea at all, really. There have been other efforts over the years, and I believe there are a couple places in Europe which actually will install self-leveling pad systems.This has been a long time coming.
It wouldn't. The JS metal pads would still have to be changed out as often as JS metal pads would usually have to be changed out when installed conventionally, I would imagine ?I can see how it would reduce reseating, and how the material itself might reduce rep adding, but I'm not sure the self levelling feature itself would reduce repadding?
Actually, JS does sell pads which are installed without any pivots required. They have been available for at least 7 years or so.......but while it may not be an absolute requirement when using leather pads, I think it is a real necessity when using rigid ones (to ensure perfect sealing by allowing some flexibility to the rigid pads). Again, that's just what comes to my mind without any experience with any of these systems...
Pete Thomas - the self leveling pads seal better because a regular pad moves more in the front than the rear so the more you press the heavier you press te front. With the self leveling - the pressure at the rear of the pad is always the same as the pressure in the front. Pressure as always balanced all around the pad.Jim, I have a couple of questions.
Is then point of this to counteract any leaks that may be caused by trauma to an instrument. It occurred to me that this could be a very useful concept, but you don't actually explain in the video under what circumstances the self levelling comes into its own.
To put it another way, this is not a DIY installation so needs a competent technician to install them. The tech may well ask you what the point of self levelling is, if they have already ascertained the tone holes are dead level and the key cups are totally in line. Under those circumstances a traditional pad is all that is required, once seated it seals and does not need to self level.
However I can see the advantage of self levelling if the horn takes a knock and, for example, the bell gets knocked a bit round so the right stack keys no longer seal. In that case the self levelling would mean that the average player with no repair ability can carry on playing fine as the self levelling pads would take into account any leaks caused.
So would you say this is the prime reason why this will work well for the average player, or is there an inherent advantage otherwise, e.g. gradual inevitable misalignment of keycaps overviewed the years so might mean less general servicing?
Bloo dog - So far the pads just seem to keep working. They don't swivel very much and I'm not seeing any wear on the ball. And there is tension on the ball - no loose play to rattle or have an impact from opening/closing. I'm sure something will give out eventually because nothing lasts forever.This has been a long time coming. A properly installed self-leveling pad would reduce a lot of repadding and the headaches that go along with it. I don't think that a change in pad material alone is the answer, but this shows a lot of promise.
I can see some shortcomings to this: How do you keep the the ball-and-socket lubricated and prevent it from becoming fouled?
