    Just got a original threaded valve stem tube for my 50 from Kirby that needed a patch. Knew it going in so I thought hey I'll just get some hot patches. To my surprise and disbelief I found the EPA does not allow the sale of them anymore,must be a major source of pollution. So I went digging in an old cabinet and found 6 Monkey Grip rubber vulcanizing patches,Score! Here are some pictures for you guy's who have never seen these before.
    Here is the Tool used to hold the patch in position -

    This is the patch with the protective film in place

    Here it is with the film removed

    You clean up the area where the patch is to go,they supplied something that looks like a cheese grater. Sandpaper can be used too but I just hit it with a wire wheel. Center the patch over the hole and tighten the clamp.

    Now comes the fun part- you pry up an edge of white substance and light it! The heat and pressure vulcanize the patch to the tube, here it is lit and doing it's thing. Please don't turn me in :LOL:

    After it's done burning you leave it sit for at least 5 minutes then remove the clamp and peel the tube from the metal backer

    Here is a patch I put on over 45 years ago on the original rear tube. I had run over a toothpick of all things on the driveway. Now that I have a matching double nut tube they both will go back on the bike. Thanks Kirby! Really too bad you can't get these anymore they really seem to work

    I haven't seen those since I was a kid. Had no idea they were no longer allowed by the EPA? Shows you how often I patch a tube.

    The product's demise probably had more to do with company lawyer's concerns for users burning up property through bone-headed users.

    More like the same reason why polishing compounds had to be reformulated. Who knew that these were the major sources of environmental damage? Good to know that the world is now safe for fracking, BPA, triclosan, microbeads, glyphosphate, etc etc. It smells like corporate politics and no amount of bathroom air freshener is going to help.:devilish::poop:

    I agree with you red69. I figured out 20 years ago In high school that the more safety decals/labels I see the dumber society gets.

    I remember using those when I was a kid. They worked great. I seem to remember, when lighted, it smelt like firecrackers.

    There are some vacuum cleaners that have some disgusting sick warning labels on them because of morons too.

    Makes you wonder how humanity made it this far. I mean, Nerf-foam coatings over everything and safety enclosures for protection from those things that couldn't be foam-coated have only existed for a generation, or two. A dumbed-down society is easier to control. Neitsche ("what doesn't destroy me makes me stronger") and Darwin are probably laughing from beyond the grave.:p:p

    Overzealous litigation protects stupidity.

    I just pulled a double nutted IRC tube out of a k0 rim. I counted EIGHT patches on the tube.

    Are the double nutted ones worth anything or just the nitto and bridgestone tubes?
