Compression Release Valve Adapter
This is an experiment for my Farmer buddy in Illinois. He has a 1939 International F 20 that will not turn over because of high compression. The plug port is 2 1/2" in from the surface of the head so we are going to try this to see if it will be enough with the just one valve and if it will fire with the plug that far away! The other option would be to get a thicker head gasket!
I added some shots of milling the hex on the end of the adapter and of the aluminum die holder I had to make to thread the other end of the adapter

Some fancy machine work!
Assuming gasoline, I guess you crack the valve to get it running then shut it? Setup is like the old "anti-foulers" for keeping plugs clean on an oil burner. Thinking it should fire ok but the timing will need some tweaking.
Just one ?
Seems strange that the original setup can't crank with enough oomph. Could always try a racing starter or heavy gauge wire to the starter or a 24 volt source for it.

Thanks, Bruce. I don't know the whole story on it. It may have been rebuilt as the cause from the difference from stock. It may take 4 of them...or a different starter . I just build what is requested!!
cheers, Jim

Interesting, very interesting. I think the way I'd go is with the thicker head gasket, but that would take all the fun out of this experiment.
Nice work with the machining.

Thanks, Cliff...shipped it today!

You sure are a jack of all trades Jim. You always make cool stuff.

Thanks, John. Variety is the spice of life! I don't make complicated things but all kinds of simple ones!!!

I’m curious to hear if this will work. Looks good if nothing else!
Imagine trying to get that through TSA at the airport?

Thanks Buck and Ron.
Hi buck, I'll let everyone know. He should get it by Friday!
Hi Ron. I just hope he gets it through the mail. I taped the box round and round. Two years ago I made box full of steel parts for John Goodwin at the sawmill in Arizona. I shipped them in a Priority box- one price for what ever you can get in there. John got the box but it was empty. I tried to call the Post Office recovery place in Atlanta and went to our post office for help to get them back, but no luck. I shipped them through the mail shipping place at Rite Aid and paid the Priority rate but they did not give a tracking number so I was out of luck and had to make them all over again.

One thing I find fascinating is you have a spark plug threading die!
Hi Bruce. what happened is I bought a pair of taps for 22mm x1.5mm. One is a taper tap and the other is a bottom tap. I ran them in 1" and the new plug would only screw in half way. The 22 mm plug out of my 1928 McCormick Deering engine did the same thing. I'm thinking maybe the pitch diameter of these taps is about .004 too small. It did not take much to run the die over the plugs and they want right in. I had to buy a die to make the male end that will screw into the engine. I can't chase metric threads on my lathe...unless they have a 2 mm pitch which is almost the same a 13 TPI.

Looks like it would make excellent anti theft device!

It would if it could fire a 12 gauge shell!!

I saw an antique show on tv one time and they were working on a tractor that used a shotgun shell to start the motor. You unscrewed a port on the side of the motor, insert the shell, then hit an external firing pin with a hammer and the motor starts! Pretty inventive!
Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
Hi Rayn. I saw that same show. I think they used that on other type of vehicles as well. Imagine doing that now a days firing a shotgun shell to start your car? They would have a cops all over you!!

There was a show on early tractor inventors (maybe same show as Ryan saw?) and to get the motor turning they used a rifle case w/primer.
Invention is a mother!

You may be interested to know a lot of radial aircraft engines used the same starting method, they were just a little bigger than 12 gauge though.
The Mk 8 diesel anti ship torpedo fired from a Oberon Class Submarine had 3 x just in case one failed, the hammers were operated by the propeller turning in the water upon discharge

That's where I remember physically seeing them! Old radial aircraft engines.
Seems like an intelligent way to get a motor going before there were more efficient systems. It’s also old skool badass cool to start your engine using a shotgun shell…back when men were men and sheep were scared…
