   I'm in need of help finding a part for my bench top mill , RF45 clone
. It's the same as the Grizzly G0484 and they show the part as
discontinued . I'm looking for a replacement X axis lead screw nut . The
Grizzly part number is P0484032 , maybe someone is making a replacement
since there must be 10's of thousands of these machines around . The
thread is Acme 15/16 (24 mm) diameter with an eight TPI thread . I've
seen articles about people making replacements using plastic - maybe
ABS? - and heat/pressure forming the threads but I'd lots rather find a
direct drop-in replacement .

 Maybe Jet has something. Their JT9 and JMD45 mills look similar:

 Manual link to pdf on that page has a parts section.
 This might be the part you're looking for but you won't like the price😬

   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 .
