Brad Dorsey Posted August 14, 2020 Report Share Posted August 14, 2020 Is there any easy way to put replacement rubber tubing on the old-style feet of Kun shoulder rests? I replaced some for a customer today. The tubing is standard surgical tubing. I have some that I bought at a drug store which exactly matches the tubing sold by distributors of Kuns. I tried lubricated the tubing and the feet with corn starch and with water, I tried softening the tubing in boiling water, I tried pushing the tubing on with my fingers, I tried pulling it on with pliers, and I tried turning the tubing inside out back on itself and unrolling it on. I eventually got them on, but it was a struggle and it took much too much time. Is there some trick to this that someone here knows? Quote Link to comment Share on other sites More sharing options...
Violadamore Posted August 14, 2020 Report Share Posted August 14, 2020 For forcing lab/surgical tubing onto fittngs in general, SCUBA-grade silicone lubricant. Quote Link to comment Share on other sites More sharing options...
duane88 Posted August 14, 2020 Report Share Posted August 14, 2020 Baby powder,talcum powder. Do it dry. I was a Nurse in my former profession, and latex tubing is getting more difficult to find, and when you do find it, it isn't fresh and is sticky, working its way back to a liquid state. Latex sensitivity has been a problem for a while and the hospitals have been moving toward silicone for some time. Better to replace the feet with the new forks.

Bill Merkel Posted August 14, 2020 Report Share Posted August 14, 2020 i did it literally a couple days ago using tubing that i got on ebay advertised for the purpose. he sends you four cuts of it the right length. he includes instructions that say to lightly coat the arms with soap before you push the tubing on. i used a tiny bit of liquid hand soap and they slid on like butter, no tools needed. the tubing is very stretchy translucent tan colored stuff, about 3/16" id. looks identical to what was on it Quote Link to comment Share on other sites More sharing options...

barnesviolins Posted August 14, 2020 Report Share Posted August 14, 2020 1 hour ago, Brad Dorsey said: That sounds great, but do they stay on? Use just the tiniest drop of liquid soap. Then it will dry and stick the tubing to the feet. Yes, it will stay. I have done it this way for years and not had any problems. Good luck!

frizz Posted August 14, 2020 Report Share Posted August 14, 2020 I use a drop of rubber cement on one end of the tubing. It slides right on and stays put. (Bicycle mechanic trick for putting on handlebar grips.) Quote Link to comment Share on other sites More sharing options...
