Please Help Me Identify These Shaper Spindles

[james dassau]

I found 3 spindles (with draw bars) for a small wood shaper (approx. 1hp) I no longer own. I want to sell these but can’t remember which exact machine they were for. I am pretty sure it was a Powermatic Model 23 but does anyone out there have one who can verify for me (or can verify for me what machine they are for)? Dimensions below (not sure if spec’d metric or std) – see pic too.

¼” router bit collet

Overall length (without drawbar) = 69mm (2 23/32)
Diameter at top of taper = 24.85mm (63/64”) -would be 23.2 mm (59/64”)
When tightened with bit
Diameter at bottom of spindle = 15.7mm (5/8”)

½” diameter bit spindle

Overall length bottom spindle to end of thread (without drawbar) = 160mm (6 5/16”)
Diameter at top of taper = 23.2 mm (59/64”)
Diameter at bottom of spindle = 15.7mm (5/8”)
Diameter of wide flange on spindle = 40mm (1 37/64”)
Width of each of 2 slots in spindle flange = 8mm (5/16)
Distance from bottom of flange to bottom of spindle = 48mm (1 7/8”)
Length of ½” diameter cutter space between top of flange & below top thread area = 69mm (2 23/32”)
Smaller nut top of spindle (left hand thread) = 3/8”-16
Larger nut top of spindle (right hand thread) = ½”-20

¾” diameter bit spindle

Overall length bottom spindle to end of thread (without drawbar) = 178mm (6 15/16”)
Diameter at top of taper = 23.2 mm (59/64”)
Diameter at bottom of spindle = 15.7mm (5/8”)
Diameter of large flange on spindle = 40mm (1 37/64”)
Width of each of 2 slots in spindle flange = 8mm (5/16)
Distance from bottom of flange to bottom of spindle = 48mm (1 7/8”)
Length of 3/4” diameter cutter space between top of flange & below top thread area = 72mm (2 53/64”)
Smaller nut top of spindle (left hand thread) = 5/8”-18
Larger nut top of spindle (right hand thread) = ¾” - 16

Drawbars

Overall length (no spindle) = 185mm (7 ¼”)
Diameter of shaft between threads = 8.7mm (11/21)
Thread / Nut at both ends = 3/8”-16

Come on guys... someone must recognize these... any guesses?

OK, I was bored at lunch and came up with this:

The PM23 is supposed to be the same as the Grizzly 1024. It's not clear that these ever took a 3/4" spindle, plus they look different from your pics.

To my eye, they look more like these, although it isn't clear that they take a 1/2" spindle. Maybe an older model?

They look and sound very similiar to the spindles for my Powermatic model 24 shaper. Hope this helps.

Good reference, thanks.
