![]() 6956 forum posts 229 photos | Do you really need a new screw? Unless you are milling in the lathe backlash doesn't matter. The only time you need a thread particularly accurate is if you are milling in the lathe for which you could set up a DTI, or for making new cross slide screws or other tool screws for which you can use the unworn backside of the existing screw cutting in reverse. |

![]() 67 forum posts | My angle of attack was to refurbish the lathe, Bearing in mind the machine is circa 50 years old. Im waiting for parts for other jobs so i thought id crack on and rebuild it.Its a nice machine and thought id go for it and give it a service.Its very usable and does stuff you wouldnt expect from a machine of its size. Ive found some new leadscrew half nuts, and found the supplier for a DRO for the tailstock,which now works lovely rather than being really stiff to use. Stuff thats worn is relatively easy to replace so i cracked on with it. Im deeply disappointed with Mssrs Myford Ltd. I asked for the specs of the leadscrew or can they sell me one? Their reply was less than ideal, no you cant have the spec, and no we cant make you one.Cosmic........... So remind me to buy a new one,HAH it wont be a new .....Myford ......for sure.I will replace the leadscrew it as i want to use it to its full potential with all its features.i bought it with retirement on the horizon and i needed a garage hobby after work is done so wanted it shipshape. Ive worked with machines and vehicles all my career, and stuff that i find worn, i replace.OCD i guess.

25 forum posts 11 photos | Paul, did you get anywhere with sourcing any leadscrew material? I also have a similar problem with a worn but still useable leadscrew on my speed 10. Ive been looking for tr16 x 3 LH screw material but having no luck. I appreciate the suspicion the tread may well be metric acme but I was going to give trapezoidal a shot. |

![]() 67 forum posts | HI John. Alas i sold the Myford as a low priced Boxford AUD came up. I sold it to a fella who owned an engineering company, so he was going to get one of the staff to make it. regards Pauly Edited By Paul Smith 37 on 09/03/2021 12:38:09 |
