2 forum posts | Hi guys
Came across `this site while looking for Colchester lathe spares.
Does anyone know where I can get a new cross slide screw and nut for my 1970's Bantam?
Cheers

2 forum posts | Thanks for your responses guys. yes, I have tried colchester and several suppliers that must also supply their parts.
416.00 pounds (no VAT) and 65.00 pounds frieght. My jaw fell to the floor.
I can have a precision engineer here custom make a "one off" for less than half that cost.
I am waiting for one more supplier's price from the UK and then will probably get my local guy to make one for me.
I thought an "off the shelf" item might have been a bit cheeper??
Cheers
Mike

1394 forum posts 103 photos | I missed the bit in the original post that said that the OEM had the parts available but that they were too expensive ![]() Machine tool parts are always expensive - industrial machines particularly so. But the manufacturer can still supply the parts you require for your 40ish year old machine & they should go straight in, be made of the originally specified materials & to original tolerances & accuracies. The thread will most like be thread milled or thread rolled & may have been ground & the nut threaded with a special tap that initially roughs the thread undersize then finishes it (think of two taps joined together axially, with the first being a bit undersize & the thread being continuous). As you say, there are cheaper options. WMH & Raine sell rolled acme screw stock by the metre in various sizes, leads & both hands. Bronze nut blanks to suit also. Depending on how worn your screw is you could re-cut the thread to remove the wear & make a new nut to suit the re-cut thread - minimal outlay with that route (you could do it on your machine by locking the cross-slide & using the compound suitably positioned) & one used by a machine tool refurbishing company I was seconded to during my apprentice days.
