|
For all those who may be interested, I have found a supplier metric ‘dural aluminium’ tubing for Yak’s. I have around 50 metres of the 6mm O.D. air line in stock, available in lengths up to 3.5m.
I don’t as yet have a good supplier for the end fittings but do have some of these available if necessary.
Contact me off list for info.

Subject: Copper Tubing For Replacement Air Line???
I spent hours Friday searching for metric aluminum tubing to replace damaged tubing connecting the main air valve, terminating at the aft bulkhead next to the rear seat. I bought a roll of 1/4" copper tube and decided to resize and use the metric fittings from my old air line. I tried a few different methods of shrinking the tube with poor results. I decided to tie one end of the copper to my trailer hitch and the other to a come-a-long attached to another vehicle. I stretched the tube and checked the diameter with a micrometer until I had the desired diameter. My shade tree engineering worked better than I hoped for. I replaced the damaged tubing with the newly sized copper used the original fittings and went flying. I was told 1/4" tubing (un-stretched) is good for 4000 psi. I am guessing if I lose half the strength in the stretching process, I still have a safety factor of around 2. Are there any reasons why I shouldn't use copper?

To all:
Hey guys I have several CJ6's here which I am parting out. Two of them are very late model, brand new, never flown aircraft which were damaged in a trucking accident while being transported from the port. The third is a 1969 CJ6. So if you need a piece of CJ6 tubing or fittings give me a call, no reason to attempt reinvent the wheel and end up with something which may be less than safe. My inventory is now to the point where I can supply most any part for the CJ6, parts are my business.
Always Yakin,
Doug Sapp
