how to you measure a prop to determine it's diameter

[dasboata]

The indicator is turned 90* and a wiggler is attached.

Whats a wiggler ? can I see some pics of it turned 90 * with the wiggler ? yhanks Chris

This isn't the exact setup as I did this so you could see what a wiggler is.

[dasboata]

yea ok so how do you measure degrees of travel Its impossible to measure pitch with that angle and set up this is what you need

[egneg]

I have the Hughey pitch gauge. to measure with. In the previous posts I said "check" blades to see if all things are equal. And the picture was not the setup but to show what a wiggler is.

Thanks for showing yours!

Thank you, it would be good to do a quick check. This is what I use to make sure all the blades match. I can also use it to check pitch with a gizmo I made.

OK thanks Chris

Kevin Sheren made these cool tools for checking diameter while making sure both blades are the same. 3/16 and 1/4" mandrels
When I got mine I was suprised how much some of my props were off.

It took me A WHILE to figure out that to get the correct/accurate reading of a prop's diameter using this tool that you have to add half the diamater of the prop holding shaft ( 1/2 4.76250mm = 2.381 mm) to the caliper reading, then double that number. Until I realized that, I thought that all my props were much smaller in diameter than claimed

I have one from Kevin also,, the problem with them is that once in a wlile, you hit one of the buttons, by mistake, and it resets on you ,,then you have to take the alum block off to reset the thing !! other then that it is a good idea chris
