He said anything less is not enough thread grip. He said anything more is ok but the grip becomes less and less with the threads that are farther in. This is what I have used over the years and it seems to work out OK. I feel that one Jam nut is sufficient. If I were concerned about the Jam nut coming loose, I would dab some epoxy on it, after it is TIGHT. Just a small dab where threads meet the nut.

The pushrods under consideration are those that have rod end bearings on both ends. If the locknuts on both bearings loosened, the rod could rotate even though the bearings are still trapped by the bellcranks. The bearings have opposing threads; one is right-hand, the other is left-hand. So, if the rod rotates, one bearing will be screwed into the rod as the other is being screwed out of the rod. The discussion has been about how to stop the rotation of the rod before one of the bearings is screwed all the way out of the rod. There are three ways to prevent this from happening: 1) Mechanically secure one of the bearings to the pushrod via a cotter key, safety wire, peening the threads, welding, etc. 2) Be sure enough threads are engaged in the rod so the bearing being screwed into the rod bottoms out before the opposing bearing can be screwed completely out of the rod. If at least half of the threads of each bearing is in the rod when fitted, this will prevent the bearings from disconnecting from the rod even though there may be minimal threads engaged if the rod rotates all the way. 3) As a belt and suspenders method, the spacer can be used to prevent one of the bearings from screwing into the rod which would also prevent the opposing bearing from detaching from the rod. Whew! This whole situation is addressed because each bearing has opposing threads which is often overlooked by builders who haven't thought through this process. Obviously, if a pushrod is trapped by a non-rotating fastener on one end, this whole scenario is not possible. Hope this doesn't require an additional dose of caffeine! :-) Sam Buchanan ________________________________ Message 5 _____________________________________ Time: 07:53:52 AM PST US From: Canyon Subject: Re: RV-List: Rod end bearing length --> RV-List message posted by: Canyon Sam Buchanan wrote: >This whole situation is addressed because each bearing has >opposing threads which is often overlooked by builders who haven't >thought through this process. --- Sam, I just have to ask -- why use opposing thread pitch anyway?

Steve ________________________________ Message 6 _____________________________________ Time: 08:15:27 AM PST US From: "Greg Young" Subject: RE: RV-List: Rod end bearing length --> RV-List message posted by: "Greg Young" Minor correction - the threads are the same rotation on both ends. When the rod rotates about the rod ends the length does not change. Turnbuckles (cables? How quaint!) have right and left hand threads so they can be shortened or lengthened. The accepted way to protect the turnbuckle from backing out is with safety wire. Sam doesn't often mis-speak - nice to know he's human.

Im sure the pins will get a lot easier after some more use but the camlocks are great. If you dont mind using both, I would suggest using hinge pins to hold the top and bottom cowls together and camlocks to secure it to the fuse. Its easy making the backing plates and attaching them to the fuse and there's plenty of room. Attaching them to the fiberglass takes more work and there's little room. Besides, the pins holding the halves together are pretty easy to remove/install.

I have to taxi on an unimproved dirt/sod taxiway to get to my runway and have not had any problems so far. Even found grass fragments stuck in the castering nut but the prop tip was clean. Not sure if the 7A has a shorter nose strut or not but one thing is sure, the prop tip on both models will take some hits as time goes on and while the 74" can be cleaned up and cut back to a 72", the 72" may end up being scrap.

It will have a higher tip speed at a given rpm however and will therefore be a little bit noisier. Of course the 1" greater radius puts you that much closer to gravel etc. also. Because you have a nosewheel, and because any performance improvement will be very small, I'd use the 72" with any -A model.

I guess I needed the caffeine shot!! You are indeed correct; however, my mistake doesn't change the fact that the rod CAN come apart if it rotates enough to unscrew one of the bearings. I got the thread thing confused with turnbuckles. Thanks for the catch. :-) Sam Buchanan ________________________________ Message 10 ____________________________________ Time: 09:00:02 AM PST US From: Sam Buchanan Subject: Re: RV-List: Rod end bearing length --> RV-List message posted by: Sam Buchanan Canyon wrote: > --> RV-List message posted by: Canyon > > Sam Buchanan wrote: > >>This whole situation is addressed because each bearing has >>opposing threads which is often overlooked by builders who haven't >>thought through this process. > > --- > Sam, I just have to ask -- why use opposing thread pitch > anyway?

What I was trying to say was that as one bearing is being turned into the rod, the other one will be turning out of the rod. The control rod can come apart if it rotates far enough to unscrew one of the bearings from the rod. The rubber hose spacer prevents this from happening.

The servo would not return to takeoff trim from the landing trim position. Wiggling the wires and closely inspecting the mechanism didn't help, and it looked like I was facing a brief flight home while holding a lot of forward stick pressure in cruise. Finally, at the last minute, the buttons seemed to come alive again and I was able to dial in the correct trim for takeoff. The trim responded normally for in-cruise adjustments, but seemed to quit working again as I was setting up final approach trim. Back in the hangar, I confirmed that the trim module seemed electrically dead and the tab itself was able to move freely when disconnected from the servo. A 9v battery and clip leads applied directly to the MAC servo did not move the motor, so the problem had to be in there and not in the ship's wiring or switches. I pulled the servo from the elevator and immediately saw evidence of mud dauber wasp activity in the area. There were several mud nests between the servo housing and the mounting bracket. I opened the servo housing and found just a few specks of dirt inside, but it was enough to cause the malfunction. As soon as I cleaned that out, the servo worked normally on the 9v battery. I deduced that the grit that had entered the housing was interfering with the limit switch follower that is designed to be activated by the servo rod only at the extremes of travel. Any friction between these two mating parts will cause premature activation of the micro-switches and shut down the servo just as if the travel limit has been reached. Dirt particles cause the slide to be carried along by the servo rod and can produce erratic behavior in the limit switch mechanism. The final nagging question was how the wasp's dirt could have gotten inside such a well-designed and sealed unit. It turns out there is an Achilles heel: the square-section, gear-driven plastic rod that attaches to the clevis has a groove in the outer part of its length, and the wasp had filled that with mud, too. When the rod is half in and half out of the servo housing, the channel or longitudinal groove in the rod allows access to the inside of the housing. When the rod is fully extended or retracted, the rod fully fills the square hole in the housing and the unit remains impenetrable. These little wasp critters are quite resourceful! I hope the silicone sealant I have placed in this groove will prevent a return of the problem, as there is no way to escape the onslaught of these insects in the summer months, and they work very quickly. Listers might want to check your MAC trim servo installations for existing damage and then fill this groove with some kind of sealant. Just be sure whatever you use won't mechaniclaly bind the servo if it should come loose. -Bill Boyd ________________________________ Message 13 ____________________________________ Time: 09:51:18 AM PST US From: SportAV8R@aol.com Subject: RV-List: propeller indexing and engine smoothness --> RV-List message posted by: SportAV8R@aol.com Over the weekend I had to pull the cowl and prop to make repairs on a broken aluminum alternator tension arm, and thought while I had the prop off anyway I would try a suggestion I had read about in the Sky Ranch Engineering Manual. It says that a flat four engine will run more smoothly if the prop is indexed to be in the same plane as the crank pins, meaning it is horizontal when the pistons are at top or bottom dead center. This orientation is 60 degrees away from the indexing that is traditional for Lycomings, which is a concession to ease of hand-propping. Well, I tried it and it works. The difference in smoothness was noticable from very first startup, and the engine is (subjectively) smoother at all rpm ranges. The prop now stops at about 1 o'clock position viewed from the front, as opposed to the traditional 10 o'clock position. The compression stroke is felt much lower down in the swing, making it indeed very awkward and dangerous to hand prop as you have to bend way over to pull it through. But since I never hand prop my plane, I consider it worth the trade off. I'm going to take a wild guess and say the vibration level is about half what it was before. I find myself now wondering if the dynamic balance I was considering before would even be worth the cost and effort. Now, if only we could solve the exhaust pulse floor vibration as easily ;-) -Bill Boyd ________________________________ Message 14 ____________________________________ Time: 11:05:57 AM PST US From: "Stein Bruch" Subject: RE: RV-List: Camloc Fasteners RV6 --> RV-List message posted by: "Stein Bruch" The only downside is the cost, but I think it's well worth it. I have one of each, my first RV6 has the pins, the 2nd has the Skybolt fasteners. Several huge advantages to me. #1) They were quicker and easier to install. #2) You can get the cowling off in a matter of seconds with no cussing, scraped or burnt hands, etc.. #3) I think they look good. I was nervous about how they would look compared to my pin installation, but it looks quite nice. Anyway, if you can afford it, I would at least use them for the top and bottoms of the cowl. Sides are optional, but I like having them all the way around. Just my 2 cents!

IOW, a couple of threads only may not be enough to carry the loads and cause a failure which would have the same effect as one end coming completely unscrewed.
