My boss has a Reliant Heavy Duty Wiod Spindle Shaper. Model # DD32. Serial # 045

the machine has a 3/4 and 1/2 bore shaft

the 1/2 bore shaft is missing 2 nuts. they are US and they sit on top of each other. One is reg thread and the smaller one on top is reverse thread. He is trying to get replacements but we don't know where to get or the sizes. can you help?

left hand threaded nuts are available in many places.
given your description, I recommend you find someone with a thread gauge and knowledge to help.

If the shaft is 1/2" then the nuts are either 1/2 x 20 or 1/2x16. If you are not sure count the threads in one inch. The pic looks like 1/2x13 . You could order both since the cost should be minimal. Try McMaster Carr, Bolt Depot etc. Left hand nuts costs slightly more than right hand ones. The shipping costs more than the nuts, try a local hardware store first, maybe Ace.
