I'm getting help for a couple people here. Thank you to you all. I just got down from putting up Christmas lights!
I think another Dennis is printing me a set of cooling fans for the SD45 type.
Alan: Maybe .34 thick? for the dynamic fan splines. The wide question threw me? They run from the center to the outer edge.
Can I send you a pic of the real one?
Dennis: per email
The cooling fan has a metal band around the outside that measures around .135" tall on the MTH from the bottom circular fan plate so that would be .2025" in 1/32 scale. The metal grill (round circles of steel rods with the splines) sits on top of that measurement.
