Purchased this drill press from a CL ad for $75. No motor or motor pulley and was solid brown with rust but no dings in the tables. One of the two motor mount tightening bolts was broken off in the casting and was extracted. It was given a thorough cleaning, polishing of the column on the lathe, new bearings, a hammered green paint job, and tables were polished to where you can see the column in them. A 3/4 HP TEFC motor with thermal reset button was installed. the DP had an aftermarket intermediate pulley that was a real plus. However, all pulley’s on this machine were for 3/8” belts. The intermediate pulley got a slight modification with a lever at the back-bottom to aid in tightening and loosening the front belt – works great! It also got new bearings and a newly machined shaft. The table was also the “tilting” type since not all King-Seeleys of this vintage are. The drill press received two switches: one for the light, and one three pole, double throw, center off switch for the forward-off-reverse direction of the motor. Having a “reverse” on your drill press really aids in taking out broken studs on various machines. For a broken stud or bolt: grind it flat, accurately center punch, then progressively drill the broken stud with larger and larger “left handed” drill bits. Eventually you usually “grab” the stud and it backs right out. It’s a great addition to any drill press. The two orange in-line polarized plugs allow you to disconnect the “reverse switch” and take the motor off the drill press for servicing (pulley, bearings, capacitor, etc.) It also makes the press easier to move being able to quickly remove the motor. The motor pulley that was used was a smaller diameter 4 step pulley made of pot metal. This one fit the motor and was the right one for the press, except it was for 1/2” belts and was not concentric at all. So, it was mounted on a 5/8” arbor, turned on the lathe to: remove the largest pulley, turning all steps down to the height of a 3/8” belt, plus reducing their overall diameter. This resulted in a perfectly true running pulley, set up for 3/8’ belts. All the included angles must be cut correctly as they are not the same. This resulted in a “granny gear” for turning really big metal bits (Silver and Deming type.) It is very quiet when running at the lowest speed of 90 rpm right up to the highest at over 5,000 rpm. A good friend bought it and had the pleasure of learning how to restore it with me. It now “labors” in his shop.
