Hi all, a previous thread was closed, hopefully this will be more the the admin's liking.
Previous thread here: http://www.practicalmachinist.com/vb/general/frustrating-nut-320454/
The consensus was that my pedestal grinder from Portugal (in the 70's, when they were still using some inch stuff) might be threaded M16 but 11tpi. I'm as sure as I can be that it's 11tpi and not 2.0mm - the 11tpi thread gage definitely fits better.
The major is 0.6299" (16mm). I just used 11tpi thread measuring wires to get a thread diameter of 0.5703". I'm not very experience with non standard threads.
What will my ID of the nut be (external thread minor dia plus tolerance?) How much will I eventually feed a 29.5 degree compound once I touch off of that bored ID to cut the thread?
Thanks a lot, a weird thread like this is new territory for me, but I'd like to get my grinder fixed.
