For years I have been wanting to have a mechanism to move the knee of my B'port up and down. Since I have three B'ports hanging around at the moment I took a gear shaft clutch insert from another machine and adapted it to fit a 1/2 inch electric drill. I now can move the knee verticly with ease.

I simply bored a piece of stock for a press fit and turned the end to fit the drill chuck and milled three flats so it won't slip in the chuck.

Good job Paul!!

I made the same thing about 5 years ago..I keep a cordless drill in my tool box just for this purpose..

What also works, is on the lathe, take the handle on the compound off, and adapt to your drill...Now you can power feed your compound...I haven't tried this though..

You sneaky bugger!

Now just how in hell are you going to get arms like a gorilla using a damn drill to do all the work, huh? http://bbs.homeshopmachinist.net//biggrin.gif

When I saw something very similar in a catalog a few years ago I decided I needed it right now! But what I did was bore a hole in the end of the knee elevating shaft, and silver braze the head from a 1/2" socket head cap screw. Now there's a 3/8" hex socket in the shaft, and I drive it with a short length of hex key in the drill motor. I don't even have to remove the hand crank, but just back it away to disengage it. With a little care it works real slick.

My shoulders are the reason I finaly did it. Rotator Cuffs destroyed on both sides, recently had surgery on left, when that side is healthy must do right.

Randy,
Your idea is one of those "thats so simple why didn't I think of that". As you said very slick.

I have- works like a charm. Especially when using the compound to cut a short taper!
