I got the Weiss VM25L, which is a clone of the RCOG-25V. It has true inch scale. The guard window on this one disables machine operation when open, and the draw bar is 7x16-18 thread, so I didn't have to modify that. It was also missing one thrust bearing, same as the RCOG-25V.
I got the same mill and had to go through this as well i did manage to cut the threads using the die but it was quite difficult thanks for your videos my friend
