1/2" LH Modified Square Tap for ML100-512 Cross Slide Feed Nut

Post by Paul Page » Wed 27 Mar , 2024 13:34 pm

I've been quoted £322 (for 2) or £277 9for 3) plus carriage of £15 for the manufacture of a 1/2" LH Modified Square Tap for ML100-512 Cross Slide Feed Nut.
Does anybody want to purchase purchase one with me please to keep the cost down?

The drawing I found for ML100-512 showed the thread as 1/2" x 10TPI ACME thread so is there a reason not to use an off the shelf offering such as on ebay, both RH and LH are listed.

My copy of ML100/512 definitely calls up a modified square thread form which is what the feed screw looks like.

Hi,
You can change to ACME for the Cross slide feed nut if you want, you will also need an ACME threaded cross slide screw obviously, however, if you have a lathe with a powered cross feed there is a drive gear on the shaft so you will need to accommodate that if you still want the powered cross feed to work.
