Drill chuck arbors

[rossbotics]

I know what you mean about those round column mill drills, they are a great machine until you have to raise the head to change tools, loosing registration is very frustrating and requires a little reset up work after, I bought one of those machines when I started my business 30 years ago just for small parts if my big mill was tied up, soon to find out it was a real pain in the azz, didn't take me to long to get rid of it.

you did a good job addressing your problem
