Old Valve Seat Refacing Tool

[Provincial]

Anyone recognize this tool? It has no maker's marks, is in a wooden box, and the instructions refer to a "Nu-Seat" ring, which I believe is an insert. It looks like something from the 1920's. The model number appears to be 677 or 672.

Does anyone want me to take more photos?

Thanks,

Is that thing hand crank operated?

Definitely pre WWII if so.

Yes, it is hand crank operated. The instructions sure look like pre-1930 in the font and layout.

Cuts a pocket for a valve seat insert to fix a pitted block/head. Modern equivalents can be the size of a Buick and cost like your house...
I'd search the paper and the castings for patent numbers or dates, which may well get you the name of the maker.

Better pics would help. I have a hand crank valve lathe about that era, but that does not look to be for that.

I have one of those too but have it put away somewhere. I bought it from Sears around 1972-3 and you checked the valve up in the tool and the hand crank would then be lamped to the valve stem. The seat "cutter" was emery cloth held into a 45 degree mandrel with a star like form that pulls the emery cloth into reliefs in the mandrel. Hard to explain. I'll see if I can dig it out sometime and snap some pics. I did a number of valve jobs with it and they all worked well. I did lap the valves as well.

Mine uses an actual lathe type single point bit to cut the valve face. No abrasive at all. I'm assuming you would lap it to get the final seating...

Sorry I wasn't very clear.. Mine had the same carbide "blade" that cut the seat on the valve and it also was adjustable for angle. We might have bought the same tool!
