Turning a ball (knob) on the lathe. (radius turner)

Making a threaded ball, knob or handle on a lathe using ball (radius) turning tool, Plans available from Steve Bedair's web site. http://bedair.org/Ball/ball.html slight adaptation of cutting tip by me :-)

Just a test to see if this helps internationally?

@Dividedhead I'm in Malaysia. I just ordered a milling machine and it's on the way but Christmas holiday delayed.. Cause the tool post of C0 lathe(4 X 5) is already very short, means the rotating body need to be very short or thin. But I already figured out the problem. Once the milling machine arrived I'll start making it. Thanks again.

@ericska Wow... miles away from here! Warmer too I'll bet!?

Good stuff. You'll have so much more that you can make (well easier anyway) with a mill'. Please let me see what you build. Either video response or join and post stills on madmodder :-)

Christmas is fun... but it does slow down progress, I'm waiting on some stuff from China.

Hope you have a good Xmas all the same.

Ralph.

Yeah, I just found your web and saw the making of this tool post. So it's a DIY, outstanding! But no hope for my C0 lathe, too small to make one.. I think I have to upgrade a larger lathe., and a milling machine. Thanks for response!

@ericska I made my base and turret on the lathe. I used the Mill to cut the slot for the tool post and make the tool post itself. You can make the tool post small enough for your lathe. you just have to re-design the tool to fit it.

Then you could try to find someone near you who would help you make the milled parts?(don't know where you are?) Or you could go old school..... hacksaw and files! Hard work but gets results.

Looks like the mounting part would be relatively easy. :-)

Where to buy that tool post?

[Dividedhead]

@ericska You have to make it! It doesn't take too long if you have a lathe and a milling machine. Other than that you could have one made..... But it has to be very specific to the height of the individual lathe it's made for.

@carter102 Indeed! :-) Glad you like it.

Awesome project, awesome music, fucking right!

@LoySisRoo Quite simple really.... I have a manual lathe and could make this tool for only a few pounds and a few hours work.

A CNC lathe would cost thousands new or hundreds to convert this one. Plus I have no real need for a CNC lathe.
