Another goofy project... diggin' into your scrap piles.

[Snaggletooth]

Geesh, I'm at it again. Onto another odd project. Before I get into what I'm going to try do this time I thought I'd check and see if anybody has access to any scraps of heat shrink tubing in a diameter of 2" with a wall thickness of around .045.

 

I figure a piece about 6" long would let me find out if this is workable or not. A few pieces would give me some room for failure. (I'm betting on that)

 

Just thought I'd shake the cage to see if anyone had some short ones laying around before I order a chunk from McMaster-Carr just to find out my idea don't work.

 

Like everybody has 2" shrink tubing laying around right?

i would send you some but what i got is a little on the used side crinkly and old would that work lol i only have a 1 inch piece left from my roll i need to order more for work

I think I have a length of 1" also it was in a kit from HF I bought.

 

Any help?????

[Snaggletooth]

Appreciate the offer but the 2" is about minimum for diameter and it looks like at least 3.5" is the minimum length. I'm not sure how much shrinkage I'm going to see on the length during the heating process but it shouldn't be too much.

 

What I'm trying to find out is if the shrink tubing will hold it's shape and how durable it will be after being heated over a form and slipped off to be used as a protective sleeve on a device.

 

Always something to play with.

If I remember correctly (not a sure thing) shrink tube shrinks 40% or more. if you shrink it over something round and don't shrink it to it;s max it will probably hold its shape.

 

Not sure how much protection this stuff has other than on wires.

 

Just for giggles I look to see what I have and get back to you if I have something that will work.

Not sure what your project is but would one of these products be usable for what you are doing?

I thought of this stuff as I was reading your posting:

Then I thought of this stuff, but again, I dont know what your project is.

Find a phone guy working on a box or a line or maybe a com ed guy, I bet they toss tons of those scraps

I have some here, but it's about 1.5", hard to measure, but not big enough for you. It shrinks 40% and we use it to rubberize wooden broom handles so that a corn broom with a wooden handle will pass meat inspection. It does a very nice job, so nice in fact that the inspectors wondered where we got those handles,,,, go figure.

Bought a bunch of that stuff at a fire sale once... real cheap.

That's about in line with McMaster Carr. $17 and change for 4 foot. Thanks.

You're right with me on the thinking but that would be the second step after shaping the shrink tubing to shape and size to add a little thickness and help it hold it's shape.

 

Both those products have been used a lot over the years on the bikes and do very well.

The spray version of the Pasticdip gets used a lot around here.
