This is a Pratt&Whitney Morris radial drill that I pulled from this scrap yard.
I dont know much about radial drills, I began researching them and this brand in particular, and took a chance that the insides were good. It was a $1500 chance, it worked out.
The machine is from the Hanford nuke site, and had little use before being drug outside. as is typical. Opened up first time since new.
This is what is behind the big aluminum front cover. Lower left, quill counterweight connected to the quill with a chain. This also has a ratchet safety brake on the quill, in case the counterweight chain fails. The quill is heavy, and has 10" of normal travel.
Lower right is the hand and power feed gears. In the lower center is the feed clutch.
Upper gears are the spindle drive, that is driven by the large bevel gears, on the splined drive bar.
This is the lower worm gear drive for the arm lift, the long screw up to the column top is stationary, the nut rotates by the worm and separate motor.
The arm lift also has a captured safety nut that idles along with the driven nut. If the driven nut should fail, the safety nut will catch the arm.
The machine is lubricated by two oil pumps, this is the drive for the gear type oil pump at the top of the head, nice American machine tool.
This machine is much easier to clean up then the B&S mill that was from the same yard.
Precision quill, uses three ball bearings at the nose, and a Timken bearing at the back end.

3ft arm, 9" column Mt4 light duty 3hp drill, weighs 5250 lbs without tilting box table.
