FS: UK only Long ball screw

Header says it all.
Uk only due to size. I have a 40mm diameter ball screw with a travel
of eight feet. Ideal for a large full sheet router. Complete with
antibacklash double nut. Ground class one screw, not rolled. Made By
Thompson. 3 months old, these are in excess of 2,000 pounds new.
Removed from a laser cutter when we changed over to rack and pinion.
Please contact me off list.
