1" Id Hdpe

[Italteen3]

Are there any sources of 1" inner diameter hdpe? Rather not use 1" pvc as that proposes a shrapnel hazard. Though the chances of such a small shell even cracking pvc I would rather not test any of those chances and stick with hdpe. Cardboard/paper is ok but does not last anywhere near as long as hdpe does.

If anyone has any info your help would be appreciated thanks!

Not that i know of, no. I actually use a used silversonic warhead cake made by phantom for my 1" shells. They work perfectly, fits nice and snug!

Yes, one inch is available. It comes on a roll, but soft enoough to be able to straighten out in a rack. I plan on building a couple small 1" racks out of what I find in the dumpster where I work. The 1" HDPE I don't think is available in black though. Still will work.

Contact a natural gas utility in your area and ask to speak to one of the supervisors - or better yet, talk to the materials & maintenance manager. Tell him you are building a science project for your kid or something and request a bunch of scrap 1" hdpe gas line. Remember to specify the DR11. the 9 has a smaller dia.

Is it so soft that it will curl after being straightened out if not kept straight top to bottom?

Thanks for your help! Hopefully I can get a rack made up for the fourth now :D. Going to stop into Home Depot and see if they have some there as I am already going there for some necessary fourth of July material.

It's be an extremely rare find to get it at HD/Lowes... like Bruce suggested, you'll probably have to contact your utility co/specialty store.

And don't rule out cardboard just yet....


Rock-Harden Your Tubes
This one is so simple it ain’t funny. Tom Dimock was at my house a couple of nights ago and I was able to get him drunk enough to find out that he increases the strength of the parallel tubes he buys from us. Basically, you just dip your tubes in Minwax® Wood Hardener, then hang them up to dry. Use the MWH without anything done to it. The tubes will soak up the stuff and once dried, will withstand far greater forces when being pressed as rockets or drivers. As soon as my hangover goes away, I am going right out and buy stock in the Minwax Company. Thanks, Tom.


Claims will make cardboard tubes last 25 years or more.

1. Clean out any debris, cobwebs, etc. Use PVA adhesive to stick down any 'flapping' edges.
2. Rinse each tube internally with a strong solution of calcium chloride in water. Allow your tubes to stand until they are just damp. Calcium chloride is rather hygroscopic and will not dry past remaining damp.
3. Using a 25% w/w solution of sodium silicate in water rinse each tube internally. Pour out the excess into your bucket and let the tubes dry open end up. There is a chemical reaction that produces tough insoluble calcium silicate in the structure of the paper. This hardens and binds the surface making it resistant to damage by abrasion and alkaline residues. When dried give the tube a fresh water rinse to remove residual sodium chloride produced in the reaction and let dry open end up in a warm location.
4. Coat your tubes externally with a mixture of spirits of turpentine 1 part (pine spirit NOT mineral turps) and boiled linseed oil 3 parts. Add 15% lampblack to the mixture if you want black tubes. Leave the tubes to dry for about two weeks, open end up... Omit this step if the tubes are for immediate use or will form elements of a boxed mortar block...

Note: I'm still using tubes prepared like this around 25 years ago, and they still function perfectly! The method of treatment is very quick and cheap once you've got set up... You can treat a hundred tubes in an hour or so for around 10 cents per tube. Painting costs around a dollar per tube and is not as effective... Regards, Myke.

Thanks for the tip! Going to see if I can find some HDPE first, then if that does not go well I can always place an order at skylighter for some parallel wound tubes. Think I am going to go with the first method you posted as minwax is a bit more accessible at the moment. Dont need the tubes to last 25 years :D.
