Summary

The Atlas 10F-81 is the support on the back of the apron that holds the miter gear that the running lead screw goes through.
This is the same part as for an atlas 10 inch and 12 inch lathe.
Also you will have to drill a 1/8 inch hole on groove side of part towards the ring.
This is your oil port.
