Ok, so I figured I'd start learning how and bought the necessary tools. I put the prop on the balancer and found the heavy blade. After filing and filing and finally getting the prop balanced I was doing the happy joy joy! So I take my newly b/s grimracer 40x57 3 and compare the weight on the digital scale with the b/s grimracer 40x57 3 that I purchased from OSE a while back.
Here's the difference in weight:
Grimracer 40x57 3 (Balanced & sharpened by them)
weight:
152.5grains
or
9.89 grams
Grimracer 40x57 3 (Balanced & sharpened by me)
start weight:
189.8grains
or
12.29grams
end weight after B/S
177.8grains
or
11.52grams
My query is this, looking over the two, the grimracer prop b/s by them is alot thinner and lighter than the one I did. So in seeing this, would the two props perform entirely different? Or is there a set parameter as far as how much weight must be taken away from the unbalanced/sharpened prop? I've read all the links other folks have posted about prop balancing, but none of them talk about weight of the prop or how much should be taken away. Or does it not matter as long as its balanced and sharpened? Your thoughts....
