T tool at the flea market

I found this today.

It won't work on our T though, because we have new one-piece valves without the little depressions to turn them with. For a buck I couldn't leave it behind though.

It would be nice if they would put the little holes on the top of new valves.

Those holes were not there for valve grinding.

They were part of the manufacturing process to attach the cast valve to the machined stem.

i was using the holes to hold the valves from turning around while unscrewing the original spring retainers and the nuts on the bottoms of the 1911 valves

Just out of curiosity why did Ford use two piece valves in the first place? It sure seems that one piece units would have been easier to make, easier to install and cheaper all the way around.

I understand it was twofold - one was it was cheaper, faster, and easier for Ford to make the valve heads separate from the round stock for the stems, less waste and faster, and the other was they could use different steels for each, to make them more durable for their different operating environments...

And I've thought about ways to add the 2 "divots" in the head of a modern valve, but I don't have the machining equipment on hand to undertake it, and if I did do that, I wonder if I wasn't making a "carbon magnet" or weakening the head...
