Taper tool for mini lathe?

[John S]

John Stevenson---Absolutely brilliant solution, using the boring head to taper turn, along with the ball bearings. What a great idea. Now I have one more justification to purchase a boring head for my Craftex mill.---Brian

Sorry Brian,
Two reasons !!

Put the head on a parallel shank mounted in the tool post and you now have an up and over radius turning attachment for external balls.

With no carving up of the original boring head and with a couple of extra shanks you now have a radius turning attachment, a taper turning attachment and at a push a boring head

Good Lord, man!!! Sorry???? I'm seeing things that I have never even imagined!!! Thank you.---Brian

John Stevenson,

Thanks very much for your extended uses for a boring head. Top stuff, I will be adapting mine in due course. :bow:

Bob, if you have an R-8 equipped boring head, you may want to try something similar to what I cobbled up. It mounts to the QCTP and turns in homemade plastic bushes. Works great!

Here's a link to a thread showing a little more detail.

thats a clever ball tool and a very easy looking design.

I am still woundering if my idea would work for the taper tool, there are some good ways shown here but I still feel that here would be alot more work involved when setting up for even a cut.

I think I will work more on my design plan to show more on what Idea I have so its more clear on what I think would work, that way people can give there thoughts more if they didnt mind

Dickeybird,

Thanks for the info. My mill and hence my boring head are M3 taper.

Like the idea of your bushes. :bow:

Thanks
Bob

Today I did my bit to keep this terrible economy going--I went in and ordered a boring head and shank for my Craftex mill. After seeing all the neat things that can be done with them over and above boring, I decided I must have one.---Brian

Just when I thought I had almost conquered my tool making addiction, you just had to post that old PM article. As it happened, I had a small 3 inch 4 jaw and a 2 mt taper sitting in a drawer gathering rust. I dragged them from the darkness and had a go at the build.

I have to admit that I'm rather enjoying the results thus far. It's stable as heck and quite easily adjustable. Now all I've got to do is make up a driving dog and cut the slots for it in the face plate.

Cedge,

yes i have a lot of faith in the older PM plans

they work and you can make them at home

glad you had a good result with that one

i'll do some more scanning and post a few more gadets they have put out for folks like us

cheers
