Default Nicest Prop Pitch Fixture?

I believe I have seen four or five nice propeller fixtures made for use with a digital level in setting the ground adjustable Sensenich composite propeller. I think it's time that we take a good look at who has the best little design and put together a 'package' that could be made available at $50-$75 that would make everyones life better that maintains an RV-12.

I see lots of 9" digital levels out there at Sears and Home Depot and they all proclaim a level of accuracy within .1 degree and a selling price of $39.95. A simple fixture and a worthy digital level would make a nice package for any RV-12 owner/operator.

Sure, I can build a fixture for my use and I'm pretty sure that someone at Vans has built a fixture that is used on the company demo unit; but I haven't seen a fixture offered to the RV-12 public?

Anybody interested?

Nothing can set the blades closer to each other than to point a laser lite to a spot on the floor.

Default Digital level

Could you explain the steps taken to use the level on the prop.

I agree. Do you have any photos of someone using this method?

Default Prop Pitch adjustment instructions

Rvator issue Number 3 for 2010, has an in-depth article by Scott on using the protractor. If you don't have it, just click on the picture, go to page 3.

For pitch adjustments I use vans fixture and a digital level per KAi and note the bubble is off a third to the right when looking straight-on, even after leveled on canopy frame, and reading 0.0. Any ideas why the difference? Woodblocks are squared. The digital level reads .08-9 when bubble appears centered.

I also use Van's fixture and haven't had any trouble setting my pitch but I can't visualize the two measurements you're referring to when you say there's a difference.

My digital level has both a bubble and a digital readout. Are you saying the bubble and digital readout on your level don't agree?

Hi Tom, Yes. Bubble is off to the right when calibrated/digital reads 0.0. How can that be?
