Purchased this machine on 3Aug2005, from a Michigan used tool store.
Sears Dunlap/Power King 1/2" spindle shaper, model# 534.09760

This machine is nearly identical to the Atlas/Power King model 411. I believe the difference lies in the miter gauge slot. The Atlas/Power King is 5/8" x 1/4". On this machine, the miter gauge slot is a 'Sears' 3/4" x 3/8".

Initially clamped to a workshop counter and strapped to a Craftsman 1/2HP 3450rpm motor.
Runs smooth as is, at 9200rpm. This is my first stationary shaper.
I plan to build a dedicated stand with a vertical motor and reversing switch.
The twisted belt tends to really heat up on the horizontal motor.

UPDATE (30Jan06):
Attached motor and shaper to a 1952 Craftsman 16x30 steel stand in the quarter turn belt drive configuration. Bending vibration and noise at the top of the stand was unbearable.
Attached shaper to a heavy old cabinet (on casters)and motor in the vertical position. Using bar clamps on the shaper base, I tuned the belt tension to minimize noise and vibration. Then I bolted the shaper to the top. (Note: shaper alignment is more critical in this position, because of the belt proximity to the base aperature, turning in both directions.
The belt is a Dayco FHP 4L420.
This set up runs much smoother than previous configurations.

UPDATE (Oct06):
Rewired the 1950s Craftsman 1/2hp 3450rpm motor with a built in reverse switch.
Added a switched outlet to run the motor/shaper.

UPDATE (11May08):
Added pics of belt guard with wrench storage (nothing fancy, just 2x4s, assembled with pocket screws).
Top of guard (5/8" plywood, wing nuts on hanger bolts into 2x4s) keep chips from getting at the motor.
Angled dowels hold dedicated adjustment wrenches.
A thin head 1/2" open end wrench for holding the spindle flats. And a 9/16 x 5/8 box wrench for the fence hold down bolts and spindle nut respectively.

MISSING:
Height adjustment lock knob plug - machined a new one from brass stock (thanks Bob D for the specs!).
One spring hold down assembly.
Part of the elevation crank.

CONSTRUCTION:
Original blue paint is under the gray.
Wooden fence facings are original and in great shape.
Base, table and main fence are cast iron.
Ball bearing spindle is fixed in the base.
The table adjusts for height (not the spindle).

Table size: 10-1/2" x 15-1/8"
Table hole diameter: 2-3/8"
Threaded spindle: 1/2"-20tpi
Miter gauge slot: 'Sears' 3/4" x 3/8"
Machine pulley diameter: 1-1/2"
