   Yup , that's what it looks like . But I don't know what pitch the 
threads are ... They don't all use 8 TPI , some use 10 .
   I saw a comment about making a brass/bronze nut to thread into the 
original , I may end up going that way . I've got just over .020 lash , 
which isn't a problem with most projects , but my current project of 
making tool holders for my QCTP is having problems .
