Thank you. So he never posted his build instructions or drawings? He just appeared so gung ho about developing his own version of debr
He never posted a complete set of step-by-step instructions with pics and product sources but he left a few hints here. If you do a search using the words "rebreather", "debreather" and "de-breather" you'll find several pics and a few specific components he mentioned which are needed to build his version of the device.
Also in a PM chat from several months ago he told me the first part to get was a breathing circuit available from Ebay and that all the other parts could be bought at a hardware store. Go to Ebay and enter the following phrase in the search box to find this circuit:
Breathing Circuit B0091000 22 mm Circuit 65115-0161-62260
Perhaps if you get the breathing circuit I listed and read through his posts using the search terms I gave above you could assemble his version of the Debreather (or something similiar). I'm not too mechanically inclined so haven't tried it myself.
