Hi Kerry
To the best of my Knowledge, Tim isn't making any Goodyear parts such as shutoffs or bellcranks any more. If you could talk him into it, they would be very expensive. Alot of work went into them. You could try phoning him anyway to make sure. Number is: 831-449-2052. Around 9 A.M. or 10 P.M. Pacific time is best to try.
Otherwise, Brodak shutoffs are available, as are some home made units from Dale Long in California. I don't have dales contact info at hand, but I can add it later.
Cheers, Les

That is a nice looking shut off!
We used to make our own very simple and reliable.
I think I can put my hands on one( I think I know where it is at)
Will post a pic if I can find it.
It consist of a bent piece of flat aluminum or steel, a bent piece of music wire and a 4-40 or 6-32 bolt and nut.

Hi Kerry,
How are you? Long long time since we last met in Brsibane.
Steve Rothwell is making a nice shut offs and he's in Sydney. Very nice units, he does one for Vintage A models and another for Goodyear and rat racers.
Here is a pic I took of both types.

Darrel Albert sells the "Dirty Dan Shutoff", very similar to the one pictured by Les.

How do these shut offs work? (I understand the down elevator activation)
For the life of me looking at these pics I am assuming that they pinch the fuel line but cant tell where the movement is. A lesson would be great.
Thanks Mark

The shut-off is comprised of four major components: a body to hold everything together, a plunger that incorporates a U-shaped wire that actually pinches the fuel line, a spring of some sort that applies the pinching force, and a tripwire.
Each of the shut-offs pictured is in the closed position, and neither show a piece of fuel line where it would go. On both, look for the U-shaped wire that goes across the bottom of the body of the shut-off and, in both pictures, is tight against the body: that is where the fuel line will go.
The plunger has a notch in it where the trip wire rests when the plunger is in the "run" position. The second example above shows the notch. When the plunger is in the "run" position (pressed toward the body), the trip wire drops into the slot and holds the plunger in that position. When the trip wire is pulled back (down elevator and appropriate linkage) the spring-loaded plunger jumps back up and the fuel line is pinched off.
Hope that helps.

Thanks Bill, This helps confirm how I thought the action works.

Here's one attached to the model with everything in place.
It uses the same basic principles as described above. However, it's not a metal module. This shutoff is based on two hardwood blocks firmly glued to the model. It has survived three 100-mile races.
The little eyelet holds the trigger wire, which goes to either to the control horn or a wire extension soldered to the pushrod.
