This stuff is hard to find. eBay does not have any.
I have a .629-9 ACME RH tap on my desk right now. No consolation for you, but as for me, I have seen a lot of taps, ACME taps are extremely rare.

They won't make one?
Try Westport then.
114 bucks. Ouch.Maybe get a couple of guys to go in with you and get a quantity discount.
AFAIK, Acme taps are usually made to order. At least all of the ones I've bought/used were.
It's for the cross feed screw on my South Bend lathe. I have to make a new nut. It's one of those items you only need once. The threaded part fits into a sleeve and is turned by a key and key slot with the handwheel. I've been racking my brain trying to figure out how to get a 5/8" to work. I have a taper attachment arrangment. I just realized that a 3/4" 8 screw turned down will work.....maybe. Still thinking. Thanks everyone. Dan

Be reminded that if the screw is not uniform, i.e. is worn more in one area, it will be impossible to get a uniform nut to screw fit, and you will need to "polish" the screw to a uniform, although possibly undersize/non-standard, major/minor/pitch diameter. The moglice or other castable [even babbit] will fit the new [non-standard] thread.

You can very likely buy a new nut for quite a bit less than the cost of a tap. Some of those nuts are fairly difficult to machine accurately enough, even if you have a tap.They show up on E-Bay fairly often; one seller is

Agreed, but none of the nuts on eBay are 11/16". I have begun plans to change it over to 5/8" and will not be able to use the taper attacment until I get a proper nut, but at least I can get going again. Thanks for all your help guys.

How about making your own tap?
No biggie really.
