I have an older model Craftsman 12” lathe that has a handwheel in the tail stock (wheel is in the middle of the tailstock). I just began turning peppermills and its a little difficult drilling the 1 1/16” hole with a handwheel. Is there a way I can convert the handwheel to crank that fits into the end of the tailstock?

Thanks so much!

John

John back in the olden days some cars were aftermarket equipt with what we called a suicide knob. Simply put it was like a gearshift knob on a spindle attached to the steering wheel. This was in the days before powersteering. You could generate tremendous torque with these things. I think with a little ingenuity you could come up with something like that for your lathe.

or something as simple as what I came up with for my bandsaw;

I have since cut off the upper portion of the brace. This thing, ugly as it is works flawlessly. I cant believe I did not think of it before.

I posted the issue of converting my Craftsman lathe hand wheel tailstock to one with a crank on the end of the tailstock. I’ve been looking for a whole tailstock replacement but to no avail. The bed is 2 1/4” tube that the tailstock fits onto. If anyone knows where to get one or has one it would be greatly appreciated.

Thanks again,

John

John, can you post a picture of your tailstock? Might help folks understand your situation and give better suggestions.

if you are going to be drilling often in the future why not make a tail stock for drilling specifically. just a few pieces and a little time fabricating and you can make a lever tail stock so that you don’t have to crank it in and out just run the lever. I have one made for drilling and one for taking out the inside of a bowl. her is a hot of the bowl cutting one.

Here’s an image of the existing tailstock. I’m not sure if I can remove the hand wheel and thread the inside of the tailstock to fit a hand crank at the end therefor the reasoning for replacing the entire tailstock.

That is a pretty slick modification, REO. I’d love to see some pictures and an explanation of how you designed it.

John I have a different Craftsman lathe but the same issue, drilling with that little tailstock wheel sucks b@lls. My plan was to make a wood crank to replace the handwheel.

Not sure what yours looks like but here’s my tailstock wheel.

I planned on making something like this from a good hard wood.

But after seeing JumboJack’s bandsaw mod, I’m might give that a try.

I’ll get up a drawing for it and post it. it would help to get some pics from the OP of their tailstock and some dimensions of the bed rails and center height.

Here are a couple drawings of the mechanism one with the quill retracted and the other with it extended. dimentions can be fudged for the application. I use shoulder bolts in drill reamed holes for the conection points. this also helps to keep the quill from turning without a key.
