I'm new to this bulletin board. I am planning on building a toolpost grinder and milling attachment for a moderate sized lathe. Could anyone who owns a 8,9,10 or 12" Atlas/Craftsman, Grizzly or South Bend lathe please tell me what the distance is from the top of the compound slide (@T-slot) to the center of workpiece (chuck or collet)? I want to make these assemblies fairly universal amongst the three types of lathes. If you want to take the time to measure the T-slot demensions and the ground surface area of the compound, it would be very helpful also. Please specify the make and model of lathe you are responding about.
