Doc's surface grinder. Runs in large bronze bearings and is castmarked "Union Twist Drill Co, and the state (hard to read) on left side of headcasting. Is well used, but still holds to couple tenths if part is reversed and ground again. Head swivels for angle grinding and the riser blacks are NECESSARY for use with mag chuck to get small parts up enough to grind. Would like to know if anyone has any info on this machine. docs_surface_grinder.jpg Irby Jones 12/4/2006 irby jones at cox dot net
