I have a 1965 Cherokee 140 and was wondering if anyone has any recommendations on a control lock for it? The 172 I flew had a hole in the control shaft, to simply place a control lock in, but the Cherokee doesn't have that.

Have seen some people use the seat belt to keep it in the aft position, so maybe that is my best bet?

You put your seat belt around the yoke.

The POH for my old '77 Cherokee 140 simply said, "Aileron and stabilator controls should be secured with the front seat belt and chocks used to properly block the wheels."

That involves the stabilator being secured in the full-up position, which is not ideal in gusty winds. But at least the Cherokee is less susceptible to upset than a high-wing.
 
I bought a bungie cord assortment pack from WalMart and wrap a bungie cord around both yokes like the picture in post #3. I also run one from the yoke to a rudder pedal. Inexpensive and does the job. My plane is hangared at home but thats what I do when I'm away.

Not a bad idea
 
I wonder when they started putting them on Cherokees. My '69 has a control lock as you described above..not the seat belt.
 
On my '68, I just used the seat belt. Nothing to get lost or have to look around for. It only takes a few seconds to buckle it and it gets the job done.

Does your '69 have a hole drilled through the control shaft like Cessnas? I seem to remember that the '69-'71 Cherokee 140s we had in our flight school had pin-type control locks that went through the shaft like that. But my '77 Cherokee 140 definitely did not, and the POH only mentioned using the seat belt for a control lock.

Well...I guess I could just go that route.

Yes, the pilot's side shaft and guide has a hole drilled into it like Cessna. The control lock has a little red flag that covers the ignition switch when inserted into said hole.
 
I just push the right seat back forward and slide the seat until the back is pushing on the yoke....

Using the seatbelt is the POH recommended method on later PA-28s. Dunno 'bout the -140. There are a couple different strap options from third parties.

I just use the seatbelt and it has been fine in windy Wyoming although the method does invite the tail to lift with tailwinds.
 
Here is a club made gust lock that was used where I trained. It was used on PA-28-161 and 181 aircraft. Seems to do the job. The metal hook clips underneath the panel next to the handbrake, each eye goes over the yoke horn.

I've used my seatbelt for my 1980 PA28-181. There was an AD/SB? recently of cracks somewhere in the yoke/connection system in 2 aircraft, IIRC. It was hypothesized by some poster that maybe it was related to seatbelt usage. Despite this, I continue to use the belts, but while I have pulled the belts so that there is little play, I have never pulled so hard as to put what I interpret as unnecessary strain.

I have one of these and it works well. Yes, $40 for a strap. I initially thought no way, but eventually wanted something that didn't look like a home brew kludge.

I still don't understand how this would work if you don't have the throttle quadrant?

That quadrant is where "most people" put the screw in snap anchor. If you don't have a quadrant, you can screw the anchor in directly to your panel and the strap should still have enough length to secure everything.

The 140 I fly has a similar rig to the one above. It has a snap on button mounted under the panel just left of the quadrant. So it would work even with the old style throttle.

For the last 10 years I have used bungee cord from Walmart to tie the yokes together.
 
I have a 1970 Cherokee 140 with the drilled shafts and am building the Cessna style gust locks. Message me if interested in one and I’ll provide a link to a YouTube video of the prototype I just finished.
 
Our 71 Arrow has something similar to this but it all depends on if you have the hole through the yoke.

I have used this gust lock for a LONG time. It works very well and doesn't require holes in anything...

I've used my seatbelt on occasions, but always worried about this. If I tighten it enough to keep the yoke still, there's a lot of downward pressure on the shaft, at an angle where there typically is very little to none, and I worry about the shaft being stressed. Somebody...tell me not to worry...please?
