Prop bending question
I have read alot of posts here on repitching props... one question I have that I haven't found the answer to When I measure my prop tips to a glass surface none of them match... is this normal or should they all be the same???
Example of my numbers
Blade 1 = .271
Blade 2 = .236
Blade 3 = .229
Blade 4 = .239
2, 3 & 4 arn't far off... but what's up with blade 1 ???

Another note to add to this... I'm using a 15in. crescent wrench and can't bend this solas for shit Blades will not bend & putting to much pressure on the wrench it slippes off... what gives??????? (not the prop blades)

Big daddy....Grab the prop 1 inch up from the back edge of the blade and go in one inch from the outside edge of the blade..I use a similiar wrench and have minimal slipping..Oh and your gonna have to use a little uummfff when bending the blades..remember your bending steel...Unless the blades were pitch blocked you will more than likely have a blade or two off....True them up and bend accordingly to your RPMs...

SNO.... thats exactly where I'm grabbing the prop... 1" in & 1" from rear! I can barely keep my impeller tool from slipping in my vice while attempting to bend (big vice mounted on a very heavy work bench)??? I was using a towel double folded in my wrench & it still left marks on the prop blade I never got it to budge... I mean not even .001"???

or do like Danny and buy the BIGGEST wrench you can to bend the blades
seems like he had about a 3 foot crescent wrench on my prop. a little mark on your blade won't hurt nothin'

AAHHHH i see..We use a differant way of bending them here..I use a flat peice of aluminium with a threaded rod that comes up through the middle of the aluminum...I slide the prop over the threaded rod onto the flat peice of aluminum and lock it down with a nut and washer..Prop does not move anywhere..Ill enclose a pic of my setup...
And ya a liitle mark on your blades isnt gonna hurt a thing....all my blades have a mark where the wrench bends on the blade...
