Spacers for Lathe Live Center
Posted: Wed Mar 10, 2010 12:58 pm
In the Lathe Duplicator section in PTWFE, it lists the minimum spindle lengths as:
6-1/4" with cup center
5-3/4" with live center and no spacer
4-1/4" with live center and one spacer
2-3/4" with live center and two spacers
As I understand it, the spacers are rods screwed in between the tapered end and the bearing end of the live center to extend the reach by about 1.5 inches. Apparently you can add up to two spacers. I'd like to use the floating tool rest and work table to work on spindles shorter than 6", so I'll have to order the spacers. The item number is #514704, they are $5 something each and on backorder.
Anyone ever use these spacers? How much runout does it add?
