Yankee Screwdriver Plug Spinner

[assweasel]

Used A Yankee screwdriver as a plugspinner today. Worked fine just had to really push it hard (to generate the speed) and be careful of the over rotation.

I just used the Plain head bit of the screwdriver and it worked fine.

Could you post some pictures. I don't know what kind of screwdriver you're talking about

They are a quick semi auto screwdriver, you push the handle down towards the tip and it spins the tip, the shaft has a very course sort of thread on it in both directions so it looks like its got dimounds machined into it.

Thats an awesome idea, i would never have thought of using one for a plug spinner.

It was mentioned on here a week or so ago by someone.

A little overkill, but effective. Just tried it, almost ripped the lock off the mount.

finally a reason to carry my yankee driver

Heh, I had tried that before and it worked, but I didn't post about it because you have to push it so hard to get the speed that it seemed really hard on the lock. I also used one of those old hand drills once (the kind with the crank handle, a large gear, and a small gear that resemble a ring and pinion gear). It was also effective if you gave it a good quick spin.

Update Push down on the handle of your Yankee Screwdriver and watch the bit end and see when the bit has made a 1/2 turn. Now measure the distance of the Yankee Screwdriver's shaft from the tip of the bit to where the shaft enters the handle.

Cut a piece of pipe to the above measurement. Put this pipe over the shaft and bit before using it as a plug spinner.

Now when you push with the force needed to spin the plug, the Yankee Screwdriver bottoms out on your pipe and can not continue past 1/2 a revolution. Hopefully this way you can save damaging the lock to badly.

Another good idea might be to find a way to eliminate the pushing force on the plug itself. Some kind of handle or spacer. The way I see this, you can dent the keyway itself pretty easily because you are pushing the bit into the warding when pushing for rotation. Also, you are pushing the plug into the shell, this might cause additional binding that has to be overcome.

Overall a very nifty tool though. I wish I had one to modify

Excuse my possible ignorance of why this would not be a good idea, but couldn't you use a cordless drill with an adapted fitting. It would require less pushing force and with the electronic brake and ratchet should stop when needed to. As i say there is probably a good reason why not as I'm sure someone must have already thought of it. I stand by in anticipation of humiliation

[Shrub]

A plug needs a quick flip/spin and a drill can not excert that, even if it was an electric one and on full whack it still has a spool up time by which time youve reset the lock.

The yankee has no spool up time due to the design of it but hey dont let me tell you other wise have a go at it im only summiseing.

From experience, I find that Shrub is right on this one. I tried it with a cordless drill months ago and the drill couldn't produce the speed quickly enough to keep the lock from resetting. Think about it, you have to get the full speed within 1/4 of a turn, not the full 1/2 turn that reverses the picked direction.

If you could get some sort of clutch thing working on there it may be in with a chance but i dont thing simply holding the torque cutout will work,

For pure and simple an elastic band on the tensio wrench takes a lot of beating imho.
