If you are a, tut-tut, Shoulder Rest user:
You may eventually find something like my latest eBay purchase useful:

SKU: Length: 0.25 Metre (25cm), Size (Internal Diameter): 4.8mm
Order number: 07-09305-15907
Item number: 251443636184
Is this due to the rubber breaking, or just becoming less "grippy", and leading to slippage?
I used to worry about shoulder-rest friction, but after glueing some chamois leather to my chinrest, I don't worry any more - the two combined are what seems to matter.
I use the Everest. I've never heard of the Tut Tut. Must be made by the same company as the Invisirest.
Eric - It's due to the rubber ageing and then breaking and exposing metal. You pay the earth buying replacement rubber parts from the SR manufacturer, so this is one way in which I improvise. It doesn't seem straightforward to buy the rubber tubing these days, and the experience I had had of Tygon tubing in peristaltic laboratory pumps was pretty positive.
My Supply Chain Management credentials led me to tubing to cover the clamps that hold my Wolf-Secondo SR to my violin. The tubing does not last forever and it's easy to cut off a piece large enough to re-cover the clamps.
Is the tut-tut version the steam powered one?
+1 to Elise.
John, first of all, I want to reprimand you for being a "megasloping-shouldered, second-class citizen" (I laughed out loud at that description).
At the risk of generating even more tut-tutting, and possibly some chortling, let me just say that all rubbers are not created equal.
Erik, you say Everest feet are "expensive, but I'd say it's worth it" - Quite a contrast with certain other expensive Everest products I know of (Yes, they're better value than, say, Anglia, but smaller firms will give better value).
Sorry John, I now realize I mixed up your post and George's post: I thought you were using a Wolf.
Elise, don't go and buy a Tut-Tut just because you let off a lot of steam and think you'll thereby put its performance out of this world.
John, my invention will fix that problem. With it, the shoulder rest couldn't come off even if you shook your viola as hard as you could, only holding onto the SR (Yes, I've done this to test it, but I don't recommend anyone else do the same).
Erik, you know that the Phantom, now out of stock, stabilises the shoulder rest by fixing it to the chinrest? Does your invention employ a similar principle?
Hey John, I actually own a Phantom that I bought years ago when they first started selling them. It worked really terribly for me, largely because the attachment system relies on your end button being a particular shape. It would immediately come loose. But even if it hadn't, it never felt quite right for me. It's fairly flexible, which means if you press your shoulder into it, it will bend and hit the back of the violin. It also increase the thickness of the violin closest to the collarbone, which I didn't like.
I look forward to seeing it - have you patented it (My father patented his stackable music desks/stands - but I wasn't conscious of a massive rise in our standard of living as a result, we still needed Mum's income)?
I like my approach to this.
John, I will probably try to at least get a provisional patent in place in case it takes off. This will at least give me some leverage if someone tries to sell a copycat device on Amazon or something.
Also, it stops somebody else patenting it, cutting you out, and making a massive profit for themself.
My inner pessimist says that there isn't a *massive* profit to be made, especially since many people claim their SRs never slip :) Always hard to tell demand until the product is on the market, though. I always figure that nothing in the violin world really makes that much money.
