Mitsui Hub threads....

[Imakedust]

Thanks very much for the warm welcome! Not to rush right into it but I have a question regarding my Mitsui 6/12. There are at least two styles of wheel hub mounts; one is a nut that screws OVER the spindle stud(male). The other is a spindle bolt that screws INTO the spindle shaft. (female) First, are there any threaded adapters you know of that screw into the spindle shaft and have a SECOND thread to accept a spindle nut? If not, and I need to thread-turn up my own adapter, do you know what the thread in the spindle shaft is?

Thanks!!

What’s a Mitsui

One of the finest surface grinders built. Top quality Japanese built.

The Mitsui I'm referring to is a manually operated Surface grinder....and yes they are an excellent machine.

Thanks easymike but as it turns out this screws directly into the spindle so hubs aren't involved.
Here is what I am looking for!! I had one on another of my machines but still can't seem to locate where to buy a couple more. The finer thread screws into the machine's spindle, and the coarse thread with the slot is to accommodate a hex nut. Any lightbulbs going off?

Thanks!

Left hand thread on the short end, with screwdriver slot, probably very hard...

Thanks guys we're close. Left hand threads on BOTH ends, just like the wheel hub. Being a Mitsui we're probably looking at metric threads, too.
