I am a Sanford SG-48 owner and a historian and I would like to better document the variations in this neat little surface grinder. I have been collecting photos off the web for awhile and would like to ask your help with some information about each machine. If you could send me the following information, either in a PM or directly to my email: dthompson4389 (at) wowway.com that would be great.
Hopefully I can come up with an illustrated timeline which I will make available. Any suggestions are appreciated. Dennis
Serial Number.
Original purchase date if known.
What state/city did you find it?
Motor information (HP, amps, rpm, manufacturer).
Elevation leadscrew:
a. External leadscrew, open gears and screw.
b. External leadscrew, closed gears, covered screw.
c. Internal leadscrew.
Elevation dial: pointer or vernier?
Wheel guard:
a. Plain.
b. Tab with mounting hole on the right (for the wet nozzle, I guess).
Belt drive: (flat or V, size if known).
A rear/side photo showing the motor mount (I have identified 4 types so far).
Spindle lubrication: flip cap oiler, large reservoir, none.
Anyone have any options (photos needed):
a. Dust extraction adapter on wheel guard.
b. Cutter grinding attachment.
c. Wet grinding system/shield.
d. 3 phase motor.
Power supply in base for the magnetic chuck:
a. Vacuum tube.
b. Solid state.
I need better photos of the power supplies and a schematic for the vacuum tube version if anyone has drawn one up.
If you have inspected the spindle bearings, what bearing number?
Anyone own the Harvey (Butterfly) re-badged version?
