Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

diy patches for flats...

not the other kind of diy patch, though i like those, too...

i got a flat today and thought about how after my last patch, there's always plenty of glue and paper left. there was a store in pdx that sold individual patches, but no one here does that i know of, nor anywhere else (that i know of). so what to do? i kind of want to figure out a way to make my own patches instead of having to buy a new patch kit every time and still having all this goddamn, perfectly good glue hanging around.

anyone have any ideas? i was thinking cutting up an old inner tube, but i'd think you'd have to rough both tubes up real good to get them to stick, patches are relatively porous, as well as being thinner, and less likely to peel off. perhaps there's a gluing trick to getting around that?

Temp fix.. light the glue on fire on the hole and melt it closed. Not a long term solution though...

Old inner tube, piece of sandpaper, rubber cement.

It's worked for me forever.

i may try this. do you use it as a long term fix, or a short term fix? i've got one patch left, and i got the flat at the end of work and walked home (i live close to downtown), so if it fails i'm not screwed...i think i may try it just to see.

but yeah, short term or long?

Long-term, mostly, i patch that way at home.

On the road, I still use the kits, so I'm not totally out from under the thumb of BIG PATCH.

i've had success with vinyl tape when s.o.l. however I've twice attempted to make patches out of old tubes and rubber cement and resulted with no successes.. I wouldn't dismiss that as impractical.. my failures were probably directly correlated to my ineptitude and impatience..

Old tubes work great for patch material. Otherwise, you can buy patches, without buying the whole kit. That's what I do, since I (also) don't need a whole new patch kit every time I run out of patch material.

to the people who are using bits of old tubes as patches: do you put glue on both the inner tube and the patch, or just the tube, like with the prefab patches?

I've seen tires with old tube patches, but never had any success with it myself.

this thread is relevant to my interests. jim-bob and others who use old inner tubes:

1. like fatbat's question. do you put glue on both the tube and the patch, let it dry, and then stick it together?
2. does it require additional roughage of the innertube for bonding?
3. anything else i should know of before never ever tearing my house apart looking for my last patch for my last innertube?

I dunno, the Park GP-2 patch is simply fantastic. Pre-glued, really compact, and made of stretchy material that gives a great seal. At 50 cents a patch, it's easily worth the saved time and effort vs diy, at least to me.

A patch kit with a tube of glue, five patches and a bit of sandpaper is about a dollar. Why would you want to cheap out on something that might leave you stranded?

Because the glue to patch ratio is always screwy.

and I'm obsessive compulsive.

re:1 - Yes, that is the proper way to apply patches, as well as being the proper way to utilize rubber cement in any instance.
re:2 - Go for it. Doesn't necessarily require, but it doesn't hurt.
re:3 - Make sure you don't damage the premises, as that may affect whether or not you get yr full security deposit back.

i tend to run out of them, or misplace them, pretty easily. and often find myself rummaging to find patchable old tubes, rather than having new ones. it's nice to know that i can cut one apart and have a backup.

because i don't want to spend money i don't have to. most people still buy into the myth that if it doesn't cost money, it's inferior. it's a very convenient myth for all the people who want to sell you stuff.

You all may know this, but if you have to patch a tube and the glue on the cap end of the glue tube is so dried/crusted you have no chance of getting glue out, you can cut the back side of the glue tube and squeeze out enough glue to put the patch on. It's a one-time use thing, you've gotta throw the glue away after that, but it'll get you home. You could also cut the cap end off, but the opposite end is much easier and less messy.

...this is assuming you have a knife or something to cut the glue tube with.

Oh, and if the tire is cut really bad use a $1 bill or a gel wrapper to boot the tire with. Then, when you get home make some tire boots out of a tyvek Fed Ex envelope. Free, and it works as good as those Park tire boots that you have to buy at the shop.

Well I'm not one of those who buy into that myth, although I do buy into the idea of not being stranded by a crappy patch that has given out....

I'm generally a fan of using the real patches, especially with road tubes. However, it's always nice to know what the DIY solution is, as i occasionally run out, and also have about half a dozen unopened tubes of glue sitting around with no patches.

I'm considering ordering the box of 100, to solve the problem once and for all.
