I saw they are advertising that Adjustable Stop Collar. It is quite a bit wider than the old collars. I have an old Mark VII. At 2.25" the new collar will hit the side of the carriage before it bottoms out. Does anyone see any problem with putting an old collar down first to raise the new wide one high enough so it does not hit the carriage?
I bought one for my Mark VII a while ago. And of course it didn't fit so I made a filler to allow it to clear the carriage. It does limit how low the table can go but it does alllow it to work.
