 |
|
I'm trying to determine the optimum cutout dimensions for the blades on the 2 bladed Hartzell blended airfoil prop as Vans sells, using the standard spinner kit. The instructions tell you to rotate the blades thru full travel to check for clearance, however I don't have an engine to mount the prop to yet, and it's not possible to move the blades without one. I am trying to get as tight of fit as is possible. I have looked at production airplane's installations, and they have a much larger clearance than I would consider aesthetic. Has anyone made a template or drawings that would provide the dimensions that I need?

The attached was floating around the archives at some point. I cannot attest to how well it would work. Also I would advise just waiting until all is on the plane and an actual sweep of the blades can be down.

Chris, I made a plate that allowed me to use compressed air via a regulator to move the blades on the prop. then used cardboard to make the template. See the following web album for the details.
I’d be willing to share the plate I made that’s shown in the album. https://plus.google.com/photos/102955683430141812381/albums/5303216259724767969

Chris,
Just to let you know the pressure on the blades can be overcome carefully, and by hand, and not damaging the prop. If you place the prop assy with the studs downward onto a soft surface like carpet, one person can apply a twisting motion pressure on one blade and another person can apply the opposite twisting motion on the other blade - again just using your clean hands. Give it constant firm twisting pressure and you will feel and see the blades begin to turn as they would in motion on the crank being affected by governor/oil pressure. Now mind you no 5 year old will be able to do this, as it does take some firm twisting, but you can do it! Once they start to twist keep the motion going until they bottom out on the stops - you will feel that it has stopped. Now the hard part! Hold the blades in this position and mark your reference points on all your parts. If you relax your pressure, the blades will just return by themselves to their initial position. If this happens, no worries, just do the procedure again and know what to expect next time! I would recommend that you perform this procedure as close to the center of the prop assy as possible (not at the outboard tip of the blades), as in the closer to the hub you grab, the better. So again, two people is easier - soft surfaces like carpet to protect all surfaces of your nice new prop (keep the plastic protection on the blades, just move them back a bit for visual spinner clearance check) - twist opposite until the stops are felt and hold it there - make your marks - go cut - put back on and test it. Tape off all surfaces on the blades so as not to scratch anything while you are test fitting.
Your other option is as someone else said - wait until it is mounted on the engine, then the above is even easier.
Your other option is as Bob (TCW) said - controlled Air Pressure applied to the input (aft) side of the hub. He has a good pic showing what he did on his site …..
Good Luck!

Lycoming can issue you with the correct cut out template. I don't have it on my iPad, however ill send it to you once I'm on my computer.
Warm regards

Hmm, I'd be surprised if Lycoming had that information, but Hartzell
likely has it, because Hartzell makes spinners for their props.
