Thanks to you and all the others for the kind words.
I don't know about that much flex. I hope someone who has wheeled that hard can chime in.
It has about 1 inch or a little less between the blades and shroud.
Derale Performance tech support wanted 1/2 inch and covering only half of the thickness of the blades.
I'm pretty close on the covering half of the blades, but I made the template for the fan opening with one inch of clearance all the way around.
I wanted some "Fudge" room on the fan centering measurements.
It grew some in thickness with the 2 layers of glass and resin inside.
So it's a little less than 1inch and is almost centered on the fan.
Finding the center measurement of the fan in relation to the radiator core is hard to do.
You can't just use a small square and go from the center of the fan out to the core, this will make the center measurement high because of the tilt of the engine.
I used a length of heavy wire bent on 90deg to get the location from the core back to the center of the fan.
That’s where I drilled for the centering rod on the templates.
Sorry to be long winded.
