Re: Bungy and Surgical tubing

Our 1.5 inch 8 inch travel double cushioned cylinder cost us $57. Suppose that could be our sponsors cost though. There is no increased length (it fit right in where we had designed and tested with a standard cylinder and the weight difference I could not detect. Didn't weigh it but if you hold the 2 cylinders side by side you cannot tell them appart unless you see the adjustment screw on the cushioned one. Not trying to argue, just relating our experience in the hopes of helping someone. Also, I did not like the talk of requiring a external hard stop. That would really screw up our now completed design.
Got more detail from the Bimba catalog.
The standard 1 1/2 in cylinder (17 -DP)
base weight .73
length 4.38 + stroke
price $39.40 + $2.85 / inch
Air cushioned cylinder (C-17 - DP)
base weight .77
length 4.38 + stroke
price $ 64.80 + $2.85/ in
Hope that helps,
God I love this site.
