At its apparent age, it probably needs fresh grease, but I am not familiar enough to recommend a brand & type. I have seen what was once some ultra tacky stuff (probably a 'sta-put' recipe) that moved very nicely in 1950, turn into really hard caked up stuff with little lubricant properties remaining by 1990. I would assume if it was turned over, some method of dis-assembly might become visible. I take it from the model number it is a 12" table? A right hefty item I assume... Homing it might be done with a flag to pass thru the gap of an opto- interrupter, then set on an index pulse from the motor. It might not align with the visible scales, but that is usually relative anyway. I home mine by zeroing it so the mounted work is aligned if its even important. For carving a chain sprocket set as the C axis from square sheet stock, it isn't as mine don't have a shaft key to locate. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
