Extreme pumping

[hsarge]

There is a thread at ************* on making your own silicone sleeves. I have made several and use them during pumping. They work quite well and you can make them in various sizes, depending on the mold you make.

Would you care to post instructions or provide a link? I think it'd be helpful here - certainly something I'd like to look at doing ...

Just go to thunders and do a search on 'silicone'. I bumped it to the top. Or, you can check members pics for the folder it is under. Just poured another this afternoon and am waiting for it to cure.

For my molds, I use both plumbing and electrical plastic pipe, and end caps.
saw the outer pipe in half. Doesn' need to be a straight line
then duct tape the cut pipe back together.
then determine how best to stabiize the inner pipe within the larger pipe's end cape. NO GLUING.
put the end cap over one end of the larger taped pipe and seal that with duct tape.
then slip the smaller pipe into the larger pipe.
mix Eco-flex.
Pour the mixture in a small drizzle in between the pipes.
Tap the outer pipe so any air bubbles will rise to the top.
make sure the inner pipe is centered.
Allow to cure 4hours.
unwind the tape, pull off the end cap (may require pliers), pull apart the split outer pipe, and roll the silicone off the center pipe. I put baby powder on the silicone ube to remove any stickiness. I use the Eco-flex 0030 sample kit and make at least a 6 8" tubes. Once you mix it you must use it any left over will cure. PartsA and parts B, unmixed will last indefinitely if the lids a screwed on tight.

Personally, I make open end tubes. You can make closed end tubes if you seal the top of the inner pipe an make the outer pipe longer than the inner pipe. Hope this helps.
