Tailstock Taper attachment

With the beautiful summer and fall we have had its been hard to get back into the shop but I was able to finish this tailstock taper attachment based on a drawing I downloaded, my stock was a bit different sizes so I made it my own I added another set of holes to increase the adjustment available. I used mt2 to jt1 adapter I had and cut the taper into the disk for mounting. The slot turned out really well after a bit of stoning its a perfect fit. I added the center reference not sure yet if I will tick off marks as the drawing had. I reused a center point I had made long ago. I haven't tried it yet but hope to soon.

Did you consider a live center instead?

I have started something similar. I found an old MT3 with tang boring head in my old mill tools drawer. It prolly came with my mill/drill. My lathe has an MT3 tailstock that will acommodate a tang so I've been playing with using the boring head to offset a live center. It seems to be not so easy.......

You had me at tailstock!
Can you, will you, share those drawings?
Nice work! Great execution!

Thanks for sharing

Yes, please for the drawing(s); I have a small straight shank live center (I can’t remember where I got it) that could be incorporated. Thanks!!

Thinking out loud if your tailstock was low you could use it vertically too.

I assume you mean to correct a tailstock induced error. Might be easier than correcting the error on the tailstock itself. The setup would be tedious though.

If you meant cutting tapers, then I think the math isn't trivial and its too hard on the tooling when it's not cutting on center. Very very small tapers on large stock maybe.

I definitely thought of a live center but my will wanted to try it this way first to see how it works.

Got down to try it this morning working well, looking like a live center will be a near future project as this looks like it will be handy to have I'm glad I made it. I think my resistance to the live center was the loss of adjustment space close to the center but overall it will make it easier to use.
the same site has some plans..
