I'm guessing bolt holder... ;-)
Could it be
a tail skid for your 9A?

The schelbobweflagaltor is a staggered alignment offset leveler.
While originally conceived in the 1940's by maintenance mechanics at forward airstrips who had minimal support, the new SCard version takes advantage of state of the art engineering and modern manufacturing processes.

Why of course it is, and a fine one too. Constructed with aircraft 4130 tubing, treated for the ultimate in corrosion resistance and designed for one handed installation with properly secured fasteners. With it's advanced crimped and sculpted ends, it has multiple uses and is a fine addition to any builders tool box. I certainly want one, but will have to wait until that stage in my building process. (where i can figure what the heck it is used for, much like the nice Avery tool kit I got, and eventually found a use for every single tool)

Hmmm...
Rudder lock is my guess.
Rudder lock is my guess.
My new bullet proof rudder lock of course.
Over the last six years and 1300 hours, I've turned my fair share of stainless wire gust locks into pretzels. Some of those times I wondered if I would ever get the "gust lock" separated from the airplane, and the rudder unlocked, it was waded up so well. All the while thinking to myself that I'm insane to keep repeating a known failure condition. I finally got off my lazy butt and took an hour to fix it right. This locks it solid whereby the next failure point is the rudder stop.
For those of you with little tiny rudders, understand that the -9 and -7 rudder is Huge! It requires a substantial gust lock. I think next I'll make up some other sort of contraption for the other side.
Yes, it was made out of the mighty pile of scrap tubing that I prepared special for Dan over the last few months.

I was thinking kinda the same thing. I'm sure that *you* would never forget to remove it, but what if you let someone else fly it?
How about something out of moderately stiff spring material, so it could be overpowered by the rudder pedals if someone (not you, of course) managed to get in the air without removing it?

(I do like the concept; I've never come up with a good solution on my -4.)

I was just going to say that if you worked for NASA you would make a redundant one for the other side.

I guess someone somewhere will say that it has happened, but I just dont get it. How is it possible to taxi to the runway without ever putting your feet on the rudder pedals? I have something similar, and did once attempt to taxi with it engaged. Didnt make it very far.

No, no I know what that is. It's an espresso machine! Hot water heater? A snow cone maker? Oh sorry... that's Arnold's guess from True Lies..

NASA critical systems were always tri-dundant
. Even if you had one go down you still had 2 to go...Bob
Never underestimate. Once a guy took off in a Cessna 170 with the seatbelt tied around the yoke! Full up elevator and full left aileron.
He broke the airplane.

Many years ago, knowing full well how dumb a smart person can get, I designed a control lock for my Cessna. It doubled as a tailwheel towbar, and the length needed for that fit nicely in with the main additional criterion as a lock: I deliberately made it so that the pilot couldn't sit in the seat if it were still installed as a control lock.
But there's nothing preventing someone from taking off with it attached at the tailwheel.... Hasn't happened yet, though. Ditto for someone using it as a control lock on the non-pilot side of the plane.

You guys are all wrong. The pic doesn't show the whole thing but it's clearly a vice. Duh.
Think maybe that was my point?

Scott,
What is your method to make such nice flattened areas in the tubing? I have tried using a vice, but they don't look nearly as nice as yours. Are you using heat? Is the tubing 4130, or something else?
Good work!

Sorry guys, everything is for sale, but I just cranked this out for me in the shop. It really isn't worth what I would have to sell it to you for in order to cover my time.
Don't be too impressed, just quick and dirty. 4130, no heat on the squish. A vice with some jaw covers, a socket to produce the nice radius, and the end of the flat cleaned up and welded shut.
