you might contact Rodney at Silent submerg, i know he had something like that in a breather he made. He might be able to help. i would also think a medical supply company would have something like that for the resperators.

"McMaster-Carr sells a range of neoprene-coated nylon bellows ranging from 1 3/4" O.D. to 12" O.D. If I could find a suitable tube for the main housing (approximately 7" I.D.), I'd use the 6 3/4" O.D. X 5" I.D. bellows for the outer bellows. This would need to be about 9" long to give a maximum counterlung volume » my vital capacity » 4 liters. An inner bellows measuring 3" O.D. X 2" I.D. would give a discharge ratio of about 17%. An 8" X 6" outer bellows would allow a shorter counterlung (at about 6 1/2") and would give a choice of 3 1/2" X 2 1/2" or 3" X 2" inner bellows for a discharge ratio of 18% or 12%."

A little pet project. I am trying to come up with ways of removing the CL and CL case on my KISS and make a Accordian style CL at the base of the unit. Should be simple enough, just have to track down the parts.

Are you thinking of putting the bellows below the scrubber?

This erm, isnt going to give you a very nice breath at all. if you go vertical, it'll make the hamster cheeks experience of rolling onto your back something that you remember fondly.

Still, winter projects are all about trial and error

Its better that staring at the ice waiting for it to melt. I am well aware of the WOB in any other position but prone, but I would like to see for myself. Plus I would really like to get rid of the CL case.

take a look on the HS-explorer website, you can see a pic of tom mounts unit on there. I beleive he dived it for a while sans-case.
