G’day,

I was poking around the Photosite and noticed that Chuck Aulgur has posted
some good detailed pictures of Jim K’s production reaction arm system.

http://www.gmcmhphotos.com/photos/showphoto.php?photo=31932

Now all we have to do is convince him, Jim K, or the engineer who reworked
Chucks' prototype design to make it cheaper to manufacture to run stopping
distance tests.

I'd like to see panic stops from 25-30 and 60-65 mph.

I'd suggest the tests be done with:

1) A GMC with good standard rear drum brakes
2) A GMC equipped with rear disks WITHOUT the Reaction Arms installed
3) The Reaction Arms installed

The same set of wheels / tires should be used on all three tests to
eliminate that variable and so only one set will be ruined!

Regards,
Rob Mueller

If my lotto ticket would cooperate I'd gladly be the guinea pig.

You see, my parents failed to leave me a trust fund, and it seems that
I'll inflict the same misfortune on my daughter.

The biggest cost is in the low quantity of parts.
When we ask for them to tool up for low quantities, prices go up considerably.
We hired a retired engineer to do load calculations for us so we can possibly cut cost on machining costs,etc.

Jim, with that small amount of material changing the thickness will
only help by a few dollars, much better having the heavier material.
It is a labor problem not a tooling cost. There is so much BS out
there to day by renaming things like the person that sweeps the floor
sanitary engineer. Shops that have the equipment have very little
demand for there skills as know one is making anything any more it is
all sent to China or it is not done.
