Hi
Hugh, yes it does have a face for mounting the table vertically. If you go back to page 12 you will see I had to make a thin spacer to lift it clear.
Tim, yes I came across that problem when I had a myford adapter in my 4" table. I drilled and tapped the chuck backplate 6mm through the boss and fitted a pointed grub screw. With the chuck screwed tightly onto the adapter I drilled a dimple into the thread of the adapter. Tightening the grub screw into the dimple solved the problem. I don't use the grub when the chuck is on the lathe, I don't want to damage the lathe spindle. I can use the same method on this table.
Cheers
Rich
