I purchased this sander from a fellow OWWMer in 2007.
It was missing the pulley and fence/stop.
No further info is known.

Sears Dunlap 4x36 horizontal belt sander, built by Central Specialty Division of King Seeley in Ypsilanti Michigan.
Cast iron base and table castings.
Bronze sleeve bearings at drive shaft and idler drum.
Power-Bronze finish.

The sander is currently mounted to a rolling stand with other machines.
It is driven by a 1/3hp 1750rpm Dunlap 115.7324 motor with 2" pulley and a 3L belt.

Sorry, no before photos.
Competely disassembled to strip and refinish base and table castings.

Idler drum adjustment studs have straight knurling and can be removed from the table casting with a mallet and large drift punch. Reverse for installation. (One stud was at a different depth than the other--corrected on reinstallation.)

The bronze bearing at the pulley end of the shaft had excessive wear. On my metal working lathe, I machined the length of a standard hardware store bronze bearing, to match the original. I installed the new bearing in my arbor press and using it to push out the old one.

I finally found an original OEM pulley (2" with ½" bore). I've given up on finding an original fence/stop.

I straightened the dents in the edge of the drums by using the curved surface of a large diameter socket in my arbor press.

Paint: Krylon gray primer, top coat-Krylon Caramel Latte Satin #1250

Reattached tag with 4-40 screws (tapped the table casting).

The decal is a paper reproduction, from the Wiki, with a top coat of Krylon Crystal Clear Acrylic and glued to the casting with 3M spray mount.
