Bench grinder odd thread size - possible to fit a tapered spindle?
Hi all,
I recently purchased a second hand 8" grinder, and then bought a tapered spindle set and it doesn't fit. Shaft size is 16mm but thread size seems to be M12 x 1.75. Seems like it's not standard to use with a 16mm shaft?
Does anyone know how I might fit a tapered spindle or have I bought a dud?
Thanks
Pat

Bunnings sell 12mm tapered spindle.
Josco 12mm And 1 / 2" Right Hand Tapered Spindle - 2 Pack - Bunnings Australia
They (in)conveniently sell in it in a two pack BUT the other spindle is for a 1/2" thread.
There is no mention of thread Pitch

Thanks Bob, but the problem with those ones is that the shaft size is 12mm which then steps down to the 12mm thread.
So it won't fit over the 16mm shaft and therefore the thread can't reach.
I've just been on the phone with Precision Tools and it seems like it's just a silly non standard size. And AIMS are still selling the same grinder under a different brand name ("GRIP").
So looks like a dud for what I want to do. Lesson learned, just buy new.
Thanks for looking.
