Never ever ever ever attempt to repair a prop!

The only time I've messed with props, is reaming them to fit properly on a motor shaft, balancing them or shaving the ends down to fit another application.

A $7 prop is not worth repairing to risk the safety of those you fly near or the safety of property you fly around.

It's just for the purpose of testing new designs in the front yard that are likely to crash and break straight away.

There is rarely an application like that where you can't make use of a prop saver.

Yeah I'll have to get some, I have a couple but no screws.

Yes I just need to test planes in the front garden before I put a proper prop on, of course I don't start the motor until I'm out of the plane of the prop spin and there is no one else there.

Even if there is nobody around, a repaired prop will fail and the remaining unbalanced mess will bend motor shaft and destroy any structures the motor is attached to.

Never ever ever ever attempt to repair a prop. For any reason.

A repaired prop is a ticking time bomb just waiting to take someones eye out. You know damn well that the repaired one that is only used to "test things" out in the back yard will be grabbed from the prop box at some point in time. It's time to retire it either by chucking it in the trash or use the broken pieces to mix up epoxy.

+++ This

I rarely chuck them, I find alternate non-prop uses like mixing epoxy, or using them as paddles to flatten windings on motors.

It's fine, I bought lots of diffferent 10 packs of prop savers for all sizes.

No I was actually only wanting to use it for testing, I was building a scratchbuild and testing it with a powered glide test in the frontyard with various changes and it kept breaking the prop.

Anyway with the prop savers they shouldn't break aymore, I also bought quite a few packs of low cost props.

Anyway I've already chucked all the broken props.

I've broken two or three props while using prop savers, mostly when the plane lawn darted into the ground from over 75 feet.

Actually I got some motors with screw shafts that can't take prop savers but they are for existing planes that fly well already. Where I need them is for scratchbuild planes that I have to test and other planes after I have made mods to.

That seems like a good place to use propsavers, probably the only time I would use them. I really dislike the stupid things
