I have an old Flather metal lathe with missing grease fittings in the two spindle bearing caps. I don't want to remove the caps nor tap them with new threads in place. I determined the ports to be .397" X 24 tpi. I was going to add the "double depth of sharp threads" to this but got into difficulty the last time I tried this approach. I can't cut the threads to fit so can someone help?
I tried a number of grease fittings and cups but could not find one to fit. Thanks Paul
