cushion tubing for shoulder rest feet
« on: Oct 13, 2005, 05:33:28 PM »
Trying to find latex tubing for Kun feet, and the like. A lot of kids are showing up with crumbling rubber on their feet, and I can't see paying a buck and a half a pair for snippets of tubing.

Around here the hardware stores sell vinyl tubing, not latex. Ditto the hobby shops. Medical supply places only want to sell packaged catheter kits, not bulk tubing. Anybody know an online supplier?

At wits' end, thanks ahead o'time...


Hey, what happened to the Delete button? It looks like Stew Mac sells something that may work. If you know a better or cheaper source, please say so. Thanks.

You could try rubber bands but they don't work as well. I used vinyl tubing, what's yer beef with vinyl?

You may be able to get heat shrink insulation from an electrical store which may do the job - you know the kind of stuff you put over cable and then use a heat gun to shrink it so that it grips on to the cable. It wouldn't be so good as latex tubing in terms of friction for holding the shoulder rest on to the violin but would be better than no cover at all on the feet.

Got heatshrink and a heat gun, use it on soundpost setter handles and such, Rob, but I want all the friction I can get. (On the shoulder-rest feet, ladies!)

Fairview, to be honest, I never thought of vinyl as an option. Does it grab the fiddle well? Kids and their sometimes thumb-handed parents will be using these, so it has to be "user friendly." The other thing is, it will be mostly my wife applying it. She's pretty handy, but more of a musician than a mechanic. She's used to the yellow rubber "noodles," as she calls them.

Go to a piano tuning supplier.  The tubing they use for Damp-It systems (where you put water into the piano) could be made to fit your feet.  If nothing else, those suppliers should have the names of the manufacturers of said tubing.  You could contact them for tubing that meets your specs.

Fishermen use latex tubing too, for lures and things. They'll sell it in lots of different colours too. How about this place?

Wolf do spares for their shoulder rests.   Are they any good for the Kun?

Wolf spares might be OK for Kun, but at $3.25 a pair or $6.50 a quad I'll go for bulk tubing. The price point I would be happiest with is 10 apiece. Anything more seems like buying stock in the company.  :P  ::)

Thanks, Moriarty, that link looks promising. Ronnie, filling a piano with water seems too tempting to resist... :D forgive me?

I'd be curious to hear what diameter tubing you settle on for the Kun (I can buy surgical tubing by the foot at a local medical supply house).  Yes, when this stuff is available for around $1 per foot in bulk, the retail prices for replacements (for example swstrings.com has 4 tips for $3.25) seem somewhat inflated... -Steve

The typical hobby shops serve the model train, model car, plastic model airplane, and/or the gas-engined R/C airplane market. None of those use the type of tubing you need.

HOWEVER, the R/C model sailplane community uses something called a "Hi-start" for launching our model gliders. It's typically about 30 feet of 3/8" o.d. ("Outside Diameter") surgical rubber tubing, with about 200 feet of nylon tow line on the end of that. We have a little parachute with a ring on the top on the end of the nylon tow line that we slip onto a hook in the belly of the glider, and the far end of the rubber tubing is staked to the ground. We walk backwards about 60 or 80 feet to stretch the rubber, give the model a toss, and the tension in the rubber pulls the model up in a giant arc (just like a kite does when you run with the string). At the top of the arc, a couple hundred feet high, we dive and then pull up sharply, the ring on the parachute slips off the hook in the model's belly, and we're off flying. The parachute on the end of the towline opens and lowers the towline back to the ground gently, so it doesn't fall in a tangled heap.

The reason all of you would be interested is that some sizes of the tubing is the same material and size as what we need for shoulder rest feet. It also wears out, so there are sources for replacement tubing.

Hobby Lobby is one source:
http://www.hobby-lobby.com/histart.htm

They have it in three different sizes.

Aerofoam carries some really good mandrel-dipped tubing (the best kind, although any of it, mandrel-dipped or extruded, will be good enough for our purposes):
http://www.aerofoam.com/

Tower Hobbies has it:
http://www2.towerhobbies.com/cgi-bin/wti0093p?&C=PHC

All of these folks sell it in 100 ft. rolls. That should last through quite a few students. I'm not sure if they would sell smaller amounts.

The other option is to contact the Academy of Model Aeronautics (or the equivalent organization, for those of you in other countries):
http://www.modelaircraft.org/

and find out from them where the nearest R/C model airplane clubs are in your area, particularly the ones that specialize in model sailplanes. Contact those clubs and find out if anyone has any extra Hi-start tubing, or some they are replacing. They should at least be able to tell you where to get it, or may have some they can give you. The old tubing may have some cracked portions, but odds are the majority of it will still be fine for recushioning the feet of our shoulder rests.

I'll ask Eddy. He used to fly free-flight in the Nationals, now is into electric RC and free-flying rubber power; he might know someone around here. High-start removed from service, who'd of thunk it! Thanks...

Steve, I think I'll start with 1/4" OD x 1/8" ID (6mm OD / 3mm ID)and see how that goes. We had to dig around in the junk box to find an example, and found a fractional Kun with what looked like that on it. All the fiddles in this house nowadays wear various styles of Mach One or a Comford, so no tubing there. I'll let you know how it goes.

I would just buy the rubber stuff from Kun, it lasts a couple years, so its worth the cash.

Yeah, but remember Beeswing has a bunch of kids that have rests needing this replacement.  At $3.25 a pop that adds up fast!  For me it's a matter of convenience; the closest violin shop that might have the Kun replacements is about 25 miles from my home but the medical supply shop is only 3 miles away. -Steve

What Steve said. At a dime each, there could be a cookie tin of rubber noodles to pop on when she sees a kid come in with a bad one. 800% markup seems a bit steep to me, but if you just need a few, the convenience might be worth it.

I hadn't looked in here yet.  Science, not medical supply is the way to to for this.  for example at the top of a google search:

http://www.basicsciencesupplies.com/Merchant2/merchant.mv?Screen=CTGY&Category_Code=tubing

I searched on "latex tubing science supply". 

Or you could go right to the source:

Going to the manufacturers could be slightly expensive - I did find a link to one, but their minimum order length was about 3 miles... ;D

No way am I ready to get a quote from the mfgr. I did get some tubing from Stew Mac, intended to go on guitar pickup height adjusters, and it works for fractional shoulder rests, but the lumen, the bore, the I.D. is a little tight. Steve's first link looks good to me. VWR wants to sell 50 feet at a time; even that is probably more than I could use before it crumbled.

I think I'd still check with your friend Eddy first. There's a good chance you can get some for free from one of your local R/C sailplane fliers.

Hey, get them to buy the 3-miles from the manufacturer direct and then give you clippings as a finders fee!

I was figuring a tenth of a foot per foot, so if each kid has four feet, then it's more like 39600. She needs to scare up some more students somewhere. And then wait for their feet to rot and crumble. There must be a better way.
