Never heard of it, but a google search suggests it's some useful stuff - applies as contact cement, bond strength increases as it ages, resistant to vibration and expansion/contraction and it remains flexible. One thing I couldn't find was where to get it. Did you get it locally or have to order online? thanks. N.

One thing I couldn't find was where to get it. Did you get it locally or have to order online? thanks. N. I've been using it since I was a kid. It's not quite the same as contact cement because if you coat both sides and let it dry, you need to clamp the parts together and heat them, or wipe with solvent to make them bond. It's very tough stuff. It was made by Goodyear when I was a kid, and has gone thru a couple changes of ownership. Now it's made by Ashland Chemical Co.. An Internet search will turn up plenty of dealers and information. I think the old stuff is now known as Pliobond 20, and there's at least a Pliobond 30 too. We glued a ripped wet suit with it back in the '70s, just making a butt joint with a little more painted on each side, and it's still holding today.

thanks, Jim. I'll have a look around and see if I can find some locally.

I'm starting to rethink the layout of the collector... Right now, I have the 3 pipes almost parallel. I'm thinking it might make sense to converge them... Might help to shorten them at the same time.
Gonna go play after the game... ;D

well got my hydraulic clutch pull problem solved. as North and Ballvo can a test to its pull was still to heavy. so after a few sleepless nights in pain and nothing to do but think of ways to improve the heavy pull at the clutch lever( master cylinder dia. .810" and the slave cylinder at .940" it was to close to 1to1 ratio so 65 pounds at the clutch and 60 pounds at the lever.) so i made this contraption so now the master cylinder .810" pushes on the larger 1.500" piston which pushes a piston of .440" that pushes the slave cylinder of .940" so now i have a two finger clutch pull that my arthritic hand can pull with no pain. i think i will call this gadget a hydraulic torque amplifier?

Many years ago there was a device to service the HP gas charge in aircraft landing gears (instead of the normal nitrogen bottle). The device was called a "strut pump" that used shop air to push on a piston similar to your design!

Very clever! We have little pneumatic valve boosters on our big printing presses that work the same way. It's amazing how a little shot of air can exert huge force. Problem with air boosters is they are dry and they seize with friction and heat.
