Good evening folks.

I bought a few master airscrew props last night and today i got to balance them...Well, I actually did not get to balance them because the hole seems to be drilled off the center [:-]

At first,i reamed one and put it on my magnetic balancer...The blades have stoped horizontally,so i sanded the lowest point,which was a center part of the prop...Then i sanded off more,,,then a little more...but nothing helped..I was sanding prop till it was obviously oval-looking in the center...And still it didnot help.
Well, then i though that I possibly didnt ream it straight and thats why the hole not centered.
So i went and got me a new prop...Without reaming i put it on my balancer and ...the same story...One part of it alwayse heavier and goes down,but blades are alwayse stop horizontal. So then I though it could be a bent rod on balancer...So finally,out of all those props i bought last night i found one that had one blade heavier then the other and i was able to balance it..
What am I doing wrong here? What would you guys recommend?What brand of props is the best?
