Craigslist find-Rochester Michigan, Nov 2009. Too cool to pass up.
Previous owner bought it used a few years ago and it sat idle. No futher history.

Craftsman model 103.23100 12¼" drill press.
Built by Central Specialty Division of King-Seeley in Ypsilanti Michigan.
Sleeve and ball thrust spindle bearings.
Spindle nose has ½-20 threads. The original hand tighten chuck is missing.
A large Jacobs ½" key chuck was included.
Jig brackets were mounted to the table. This drill might have been used for a dedicated operation.

Included a Dunlap ¼ hp 1750 rpm split phase bronze bearing motor (date code B2_48).
Motor runs fine, dispite the fact that it wasn't intended to be mounted vertically.

Dec 2009: started disassembly, dry bearings from sitting idle, broken motor mount adjustment bolt.
On/Off toggle switch mounted in front edge of base. Many exposed wire connectors--yikes!

Sep 2010: Complete. I've dedicated this restoration to my father.
My father originally used the Craftsman 115.6962 ½hp 1750 rpm motor (with shaft arbors) as a grinder.
He also used the Craftsman keyless chuck on the RH shaft arbor. This is the identical chuck that was missing from the original drill press.
The yellow and white 1964 Craftsman Shop Chart in the background is also from my father's workshop.

This drill press runs extremely smooth. Drilled a few test holes in wood--hand tighten chuck works fine.

Restoration Details:
Drill and extracted broken motor mount adjustment bolts.
Drill and tapped ragged hole in base for cast iron pipe plug (inserted from inside of base) and ground flush.
Washed all parts in Zep Purple industrial cleaner except spindle.
Masked head bearing with rubber plugs and plastic wrap.
Blasted all cast iron parts with crushed walnut shells.
All steel and aluminum parts were wire wheeled and buffed with green compound.
The heavy rust was removed from the column with a wire wheel, then polished with a Scotch-Brite EXL Deburring wheel.
Both tag drive screws were discarded and the castings were tapped for 4-40 machine screws.
New ServiceMaster ½"x37" FHP V-belt.
Primer: two light coats of Krylon gray.
Finish: two coats of Rustoleum 7784 Charcoal Gray gloss enamel.
