I am looking at a used Delta 8” jointer and the only model number visible is Model 52-877 which designates the base part of the unit.

This appears to have a long bed on it.

The specs say-

Voltage – 120/240v
Amps – 15/7.5
PH – 1
RPM – 5000

Does this sound like a 3HP unit?

They are asking $1000 for it. Wondering what the true value is. I can’t find anything on the web on this.

Thanks for any insight leading to any details on what exactly this is.

Horsepower = voltage X amperage X efficiency of the motor (eff) X power factor (PF) all divided by 746

Don’t know the efficiency or power factor, but they are both less than one.

HP = ((120 X 15) / 746) X eff X PF = 2.4 X eff X PF

Typical eff and PF values are in the 0.8 range. That would give you a 1.5 HP motor.

Thanks. That’s what I was afraid of.

Well, I found out exactly what it is –

Looks like this model sold for $675 a few months ago.

Is this even worth making an offer on? It’s offered at $950

Is a Grizzly offering a better value?

Have your say...
