If the "read the manual" statement was followed with something of more substance. I'm not trying to call Don out on this too much. It just seems particularly out of character from him. I'm one that always looks forward to his posts and found this one just a bit disappointing. That's all I have to say about it though as I don't want to single him out any further.

Don, if you have any questions/comments feel free to PM me.

So what is the Best way to weld this poly cord stuff together? Mainly what temperature do you heat it to and any other important information about the welding process?

Zip ties work great, haven't tried welding that stuff, but I assume its possible. You can always try to put an insert into the tube (flexible, of course) and insert that into the two ends of your loop. Rubber adhesive or zip tie crimps should hold that in place.

Home depot has some latex tubing that is pretty much identical to the surgical tubing in the kit. They should have all you need!

home depot has the tubing for sale in the plumbing department.

Joining Surgical Tubing
1. Insert dowel slightly larger than the inside diameter into one end of the tubing about 1.5 inches.
2. Fold back the tubing over itself for about an inch.
3. Remove dowel.
4. Apply contact cement all around the folded back end and about an inch on the other end of the tubing.
5. Allow cement to dry until it is tacky to the touch.
6. Butt the two sides together and unfold the folded end over the nonfolded end.
7. Allow to dry and test.
8. If you need additional strength, you can add some stitching with needle and thread.

Hope this helps.

Sorry Kevin I just notice you posted the same thing.

Yeah so What is the process of welding POLY CORD? Not surgical tubing.

[riptide]

Well the tread is for surgical tubing but if you insist. They do make kits to do this.

Wear eye protection and gloves as heated poly cord likes to stick and burn.

Joining Poly Cord

1. Cut the cord slightly longer (1/4" for butt joint. 1/2" for splice) than the desired length.
2. For a Butt joint cut both ends perpendicular to the cord.
3. For a splice (stronger) joint cut both at 45 degree angles to each other.
4. Heat both ends until slightly melting. Flame or knife blade solder iron works well. (don’t burn or blacken the cord)
5. Connect both ends together and let cool.
6. Clean up joint with snips and/or sand smoth with fine sand paper.

Back to surgical tubing if anyone is still interested, we make loops by using barbed vacuum line connectors. Lubricate the surgical tubing and connector with rubbing alcohol and let it dry completely. I definitely recommend this, it worked great for breakaway and possibly again this year!

What does the rubbing alcohol do for the surgical tubing, make it grip better to the rollers?

What sort of surface do you need for the rollers when using the surgical tubing?
I have not had much luck with smooth surfaces like PVC and found paint rollers over the PVC seem to work better...

is there anything that we cant really use surgical tubing for? i know weird question but still. thank you
