Brief Description: Initial prop fitting
|
|
As I mention in the cowl fitting post for today, the prop really has to be attached in order to ensure that the cowl is properly spaced from the spinner hub. Lucky coincidence, I happen to have a prop laying around.
I've seen enough WWII movies to know how to attach a prop...you just fashion a sling of sorts and hoist it into place. Actually, that's about what I did. The prop itself only weighs about 70 lbs, but being long and expensive, it bears a bit of care when installing.
Six bolts, attached somehow by magic, hold the prop onto the crankshaft flange. Not kidding about the magic part, these bolts aren't coming out, but due to their placement, they don't allow much in the way of flexibility during installation. What I figured out was this--tighten one bolt by about two partial turns, move to the adjacent bolt and turn the same number. Repeat times six and work around until the prop is attached.
It really does look like an airplane now.
