Re: Offset tail stock -how to use it.

Hi Graham, I agree you don't need to offset the tailstock to turn tapers, but why not keep the adjustment well locked down yet available for the 'you never knows' that often occur on machines with no adjustments. I would worry just as much about the 'permanent' fix being or staying right as I would about the offset. IOW, if it ain't broke, etc. Only my opinion.

I hope not too OT, but briefly; I have been messing around with interposing a universal joint from a 3/4 socket set onto a tail center offset (from the tailstock) much more than that allowed by metal lathes. Why? I want to support a=A0long, very eccentric spindle blank. Any suggestions? Better ideas? Scorn? TIA, Arch

Arch, I'm trying to picture this, but having a hard time. A little more detail? I'm attracted to eccentric ideas :-)

Ken, I'll try to explain in a separate post, so as not to step on Graham's query. A.

You might have better luck making "face plate" to fit the live center. Next, drill an offcenter hole in the face plate to hold the live center tip. This will give you a live dead center :) Your workpiece will still have to rotate against the tip,but you will have the same problem with the universal joint. If this is a problem insert the tip in a bearing, then into the face plate.

Graham, The offset tailstock can be used for doing eccentric turnings, such as can be done with the Sorby eccentric chuck. It may not be as versatile, but you could do some very interesting pieces. You would just have to reverse their procedures to adapt to the reversed position on the lathe. People with fixed position tailstocks get the same results by loosening the tailstock and repositioning the work piece off center after the initial cuts. Try to find a book or video to explain the process. I think Sorby has a video for their eccentric chuck. Good luck,

wrt setover tailstock

On the metal lathe this adjustment would have been used

On most metal-working lathes the setover is also seldom used, as well. In some regard it is more a holdover option (like the hole for center grease on so many metal lathe tailstocks). Once you have torqued in the opposing screws at the position where the live (headstock) and dead (tailstock) centers meet, the setover is mechanically fixed until you loosen it. Why damage a functioning device? Frank Morrison

Graham,

This feature is really handy when your skew won't skew.
