Hey Frosty, the age doesn't really matter, I was just curious. It's neat to Know the history of my tools. The screw runs smoothly but the crack you see runs right through the vise. Someone must have been pounding on it and snapped the vise from the base plate. now the base plate is welded onto 3/8 plate and the rest of the vise can be bolted to the plate. If attached to the plate, the vise runs smoothly. the jaws are in rough shape but they line up nicely. If I wanted removable jaws I would need to re drill the pre existing holes which are filled up. I don't think thats necessary at this point.
I appreciate the advice on hight also. I am curently forging outside with my anvil, blower, and a smaller vise given to me by the same guy mounted on large rounds of wood. I may want to shorten my vise stump.
thomas, I am not sure about indias patents, I may have to check it out.
thanks for the replies.
