OneWay live Centre
Aug 8th, 2018 at 10:29am
 
Ive just pulled the trigger on a OneWay live Centre because I really like the idea of being able to turn your own wood nose cones to fit on it. Ive read that folks screw a blank piece of wood onto the centre then mount it in the head spindle to turn it. What are folks using to lock the centre? It comes with a knockout rod but doesnt come with any sort of pin to lock the spindle. I suppose I can turn up a short rod to suit, maybe with a larger head and hold it in place with some tape? But Im wondering what other folks are doing.

The nose of the OneWay and many other live centers is threaded 3/4"-10
You can get a tap (I prefer a bottom tap) and thread your own wooden cones or whatever

Ed: I think that Wil is asking how to "lock" the live center so that when he threads a wood block on to it and mounts it in the headstock, he can turn the wood block round.

Wil: If I'm correct on that, my solution is to put a cotter pin through the hole in the live center. I don't spread the cotter pin. As you guessed, a piece of any kind of tape holds it in place.

While I hate to answer a question with a question,
Why would you buy a device that is designed to rotate and then look for a way to stop it from rotating???
I don't think I've ever considered using my live center as a drive, I don't see the benefit. What are you trying to accomplish by doing this?

Ed. I believe the intention is to shape the piece while on the headstock, then use it on the tailstock...ala xxxx "soft touch"

I confess I didn't understand, I apologize.
Now that I'm on the same page, most people go about it this way.
Most of the time the cone or desired shape is turned as you would anything else, either using a chuck or faceplate, etc. Then the piece is drilled to the appropriate size for the threads to be tapped. For 3/4-10 threads I believe it's 21/32".

Everyone has their own method of doing things, I'm sure there are others with methods where the live center is used as the drive, maybe they'll explain their process
Turn safely

Ed: Since my post got us in this mess, I'll explain my process. I guess that I'm not "most people".    Smiley Smiley

I take the block that will eventually form the soft touch on the end of the live center, drill and tap it, then screw it onto the live center. The live center has a cross drilled hole in it that will accept a pin, nail, cotter pin, whatever so that the live center is no longer "live". I put the now-dead center in my headstock and turn the block to whatever shape I'm after. Then, I knock it out of  the headstock, slip it into the tailstock, remove the pin and I'm in business.

Doing it this way, I know that the soft touch will be perfectly centered on the live center, since it was turned in place.

As you correctly say, though, each to his own.

You can do it that way but the here's what Oneway says.

Making a Custom Wood Center

To make a custom wood center use
a blank 1 minimum, 2 maximum
thick.  Drill a blind hole 11/16
diameter by 7/8 deep.  Insert the
knock out rod through the body and
screw the blank onto the threaded
portion of the center.  Insert a spur
in the ONEWAY Chuck or headstock
to drive your blank and turn to shape
required.

Another method to drive your blank
for turning is to drill a hole and insert
a drive pin in between the jaws of
your ONEWAY Chuck.

The locking hole in the live center is not designed to "drive", it's only function is to hold the inner shaft to facilitate attaching and removing nose cones or points.

Thanks Grant, thats exactly what I had planned. Ill just find a pin the fits the hole and hold it with tape.

If you're looking to drive a wood blank that's been tapped to 3/4"-10 I would suggest getting one of these from Robust:

This one is a bit more but it's even better to have the bowl drive attachment which can be used on either side of the lathe:

I don't mine a lot but when I need it I'm so glad I have it.

The shaft IS NOT MEANT TO BE DRIVEN.
I said my piece.

If you are going to do this, I would suggest that you select something to act as a shear pin, possibly an aluminum nail. If you get a catch or something, the pin will shear with no damage to your drive.
If you use something hardened as a lock pin and get a catch, you could cause damage.
