Hi Trevor-

Trevor
I used a ray allen position sensor to drive a ray allen indicator, and a
micro switch at the up limit to kill the display entirely.

That certainly makes sense, but my info on this issue came from Champion.
I suppose it's not impossible that their reps pooched it...

I have a hard time imagining a scenario where one could properly apply any
type of dope on any male threads, and get it into the bore of the device.
Plus, a glowing deposit in the cylinder should cause pre-ignition and
perhaps lead to detonation, which could well preclude run-on ;-) Not
to mention, run on takes fuel, the absence of which is how we kill aircraft
engines anyway!

I'd give you mine, but the shipping would cost more than the material: Home
Depot - approximately $100. Check the xx Years of the RV-ator to see what
Van has to say about jigs; I fully agree with him. One of those pretty,
expensive steel jigs is no guarantee of a straight fuselage. It took half a
day to build the jig Van recommends; my variation is at
http://www.flion.com/rv6a/chap31.htm. One thing you can't see well in the
photos is that I used drywall screws to assemble it so I could store it more
easily when done. I also used lag bolts and washers to hold the longerons
in place. If I were to do anything different, I'd add heavy duty casters to
the legs so I could move the jig around more easily.

Hey Folks,
I am a 6A builder with wings and tail completed, going to purchase a
Fuselage kit from another builder and am in need of a Fuselage Jig. I've
notice them posted here on the list several times before. Do you know where
I might find one? I'll be building @ the Corona Airport in So. Cal. Anybody
out there know of one available, give me a shout here or off list @
smirdrv@hotmail.com.
Thanks.
R.C.

Good point. I've had run-on even after I've shut the mags off.
Especially in my Pitts (O-360) after I've worked her hard and the temps
are still up. I hate the stink! I've never noticed a pre-ignition
problem, but that's really hard with that big snarling thing so close up
front! I do use auto fuel in it though. The bottom line for me is the
high temp stuff in the antisieze also makes it harder to burn off.

Pat,
Thanks for the reply. I received a reply from a builder here locally
who has one available. Again, Thanks.
