Hi
My 1940's Parkson No. 1NA mill has a worn ACME cross feed lead screw and nut . The size is 7/8" x 5 TPI and it is a LH thread . Been looking for a new screw in this size with no luck. I can use a metric 22mm x 5 trapezoidal screw but I cannot find these in LH thread either !
Any ideas welcome .......Mike
