I had a request for some tall, slender candle holders about 350mm high with 8mm dia stems. I decided to try to build a support for the tailstock end that might provide enough support to eliminate the need for a wheel or string steady. The attached is what I came up with and it actually worked well. I now have some improvements planned to make it more useful over a range of cup sizes and generally clean up the design but he basic concept will remain---- I think:D
Sketching is not great but I not an artist or draftsman (person?)

If the tailstock live center has a removable center point, remove it before mounting the nose cone, so that the aid can be removed by the drift rod. I made something like this, but made the fit really snug over the barrel of the live center; learned the lesson the hard way.:rolleyes:

Cheers,
Joe

Thanks Joe. I recognized that possibility but I wanted the center for better support so I removed the set screw that holds the center in. Failed to mention that in my comments. I have already moved to a quite different design which requires a new live center and therefore some "management consultation" with the bean counter:B

Here's my solution to supporting the hollowed end of a slender turning. Make your own live centre. All you need is a bearing of some sort, even the ones from inline skates will do and some nice hardwood.

Fixer. That looks like a good solution but I cannot see the right hand end well enough to see the (I assume?) taper??
I might go that way , thanks.

Here you go Phred. No2 morse taper to fit my tailstock. Not to hard to achieve once you get the hang of it.

I did something very similar with the tailspur that came with my one of my MC-900s, which looks much like the one in the orig. sketch.

I was turning spheres at the time and wanted to change it from a centre-spur to a cup type fitting.

The "cover" slipped off the bearing quite easily so I could slip the wooden cup over instead, but when it came time to swap the two back over again... :no: Major hassles! The metal one would push back on again, but would also trap air inside and as soon as I let go it'd "pop" halfway off again.

Rather than muck around with it, I've left it as my "special" MT & bearing, for custom centres. And still use it quite a bit, even though I now also have a commercial modular system. :)
