    Subject: More pics
    Thanks to those folks who sent pics of their baggage holds, good stuff. I also need a shot of the pile of old avionics, power supplies and cables that many of removed from the CJ. About 190 lbs came out of mine and I left the flux gate compass stuff in. Craig

    Subject: M14P Gearbox wanted
    From: "Off2wildblue" <Off2wildblue@me.com>
    I am wanting to upgrade my M14B to an M14P. I am looking for a gearbox for an M14P. I have checked with a few sources Im still waiting to hear back. But I thought I would see if anyone had one on the used market that was not damage from a prop strike or something along those lines. I have checked with a few sources Im still waiting to hear back.

    Would greatly appreciate it if anyone who's mounted one of these to the engine mounts would share the hardware they've used so that I can save some time and money putting this together. Thanks. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491850#491850

    Subject: any reason NOT to go Swagelok check valves?
    I'm a "stock" guy. I like to keep things the way the design bureau designe d them. That having been said, over the years I've replaced or overhauled enough Ch inese check valves to fill a trick-or-treater's plastic pumpkin. It's gett ing old. The Swagelok replacement check valves seem like a good idea, but I'm cautio us, so: Does anybody have a single experience, observation, or reason NOT to go wit h the Swagelok replacement one-way check valves? The only thing I can think of is, "We don't have enough total hours as a co mmunity to know what the down-side of the Swagelok valves is going to be" - - but that argument is fading. Jon

    Hello Jon, It=99s a simple thing to rebuild them. Doug Sapp provides the parts and all that=99s needed are two 17 mm wrenches. For those check valves that are too far gone from internal corrosion, the replacements that Doug builds are excellent. Regardless, whether you rebuild or replace, they still need to be swapped out every few years. No way around that no matter who makes them. Just me, but I like to replace the soft lead washer with a soft aluminum crush washer that=99s been coated in WD40 to reduce deforming during tightening. Very solid seal. Attached is an image. Personally, I=99m not a big fan of the Swagelok check valves. They are not very robust. Have seen too many fail. On a flight to Oshkosh a few years ago one of the members of our group had several fail by the time we got to Nebraska from Arizona. Spent a long time on the tarmac at the Lincoln airport replacing them with Chinese ones, which kept working for the next three years. Exceptions are the Swagelok main and emergency on-off valves. They are fantastic and seem to last forever. The 90 degree, 2-port one is SS-42GF2-A-WN2 with the black handle. Attached is an image of one configured for the main air.

    Warren I agree the Chinese check valves. I use the lead seals and I also use WD40 while tightening. Do you have a part number for the aluminum seals. ?
