cracked blade labbed Bravo 1 32?

Can a cracked blade that extends about 2/3 thru the blade half way down the blade be repaired? There is no visible offset at the crack. Local shop told me they don't repair cracked blades. If you can repair a chewed prop from hitting bottom, what would be the concerns with repairing a crack on an otherwise perfect prop?

The metal along the weld can be compromised.

Something that big we consider unrepairable.

Can we do it, yes. Do we suggest doing it, no.

Taking this one step further; could you replace the blade, remove at the hub and replace the whole blade?

Re: cracked blade labbed Bravo 1 32?
 

No we won't do that.

It's scrap!

You can find someone to weld it and keep it as a emergency spare. It will crack again sooner or later.

The money you save trying to fix the prop, could cost you double in the long run. If its repaired and throws the blade it can do serious damage to the drive also. Dont chance it. Buy a new prop. :D :D

Good info. Thanks. Already bought a replacement. Strip, that picture could be my prop. Exactly the same crack placement and length.

Merc had a bad run of props the reason it cracks,The maching on the back of the blade left stress risers and makes the crack.I went thru 4 of them.had 2 warranted. the new style is machined in a different direction.I heard there was even a memo from merc stating the defective props.

I lost a blade on one it took out the gimble pin from the vibration

I have had props that had 1 to 2" cracks in them and had them welded and they held up. If they are welded and repaired correctly, they will be fine. 3 months ago I had my 5 blade repaired with a 1" crack and have run 3 poker runs with it since with no problem.
