When I bought the Nichols lathe, I found the spindle size to be 1 1/2"x8. All my G-3's were 1 1/4x8 and it seems, the "stock" thread for the chuck was M33, which apparently is the metric equivalent to 1 1/2"x8. The lathe came with a Vicmarc VM-120, which is an absolute monster. So, I donated my G3s to our turning club for their demo lathes and bought a new VM-120. Now I need to get it dirty.
