tailstock center extension

is this manufacturered by somebody?

[Jim Underwood]

Why would you need an extension? Don't the tailstock and the quill move?

[charlie knighton]

i need a tailstock center extension becasue i am making a box without a tendon, using Jerry M. gizmo for headstock holding and pulling up tailstock, the tailstock restricks my tool movement, if it were farther away i think i could have better access to bottom of box

[Roger Chandler]

Try this one out, Charlie.......from CSUSA.........

Roger is right,but make sure you have a morse taper drift to remove your center from the extension. Check the product detail sheet. I use one on my Vega 2600 all the time and they can get stuck together and you'll need a drift. Also the end you'll be working around is at a guess 1" to maybe 11/8" round.

thanks, guys....good idea on the drift

[Mike Cruz]

Pardon my ignorance, but what is a drift?

[John Keeton]

Pardon my ignorance, but what is a drift?

Mike, nothing more than a tapered pin used to enlarge holes or drive objects from a tapered hole, etc.

[Mike Cruz]

And how does that get your live centers and such out of the extender?

[dan carter]

Actually you use a drift key which is used to eject Morse Taper shank tools from sleeves, sockets and machine spindles not a drift pin.Screen Shot 2013-07-29 at 4.13.04 PM.jpg

Drift key only works though if your taper is long enough to peek down into the drift window of the extender... Don't ask me how I know that... :-(

[Jeremy Hamaker]

Mike, on the picture of the extender that Roger posted, there's a 'slot' part way down the sleeve. Theoretically, the morse taper of whatever you put into the extender will be long enough that the end of it peeks into that slot. You take the point of the drift key, put it into that slot 'across' the extender and as you 'hammer' it into the side slot, it exerts pressure on the end of the taper, encouraging it to pop out of the socket it was wedged into.

[Mike Cruz]

Thanks, Jeremy, that is what I thought, but wasn't sure. Didn't want to "try" to explain that and it start a confusion. You described it well.

i bought one with the extender, glad to know how to use it before the "now what do i do moment"

Charlie,
My morse taper extension does not have a slot for a drift pin. When my live center needs to be removed, I take the extension out of the lathe and whack it a couple times with a wooden mallet. That loosens the live center quite nicely. No mark is left on the extension and no other damage done.
