What to do with warped propellers

I don't want to give them to a reseller as we don't want them entering the commercial stream as usable engine propellers. Krafts only or they will be destroyed.

They are not much warped but enough to make them difficult to balance. One has to look closely to even notice but still ...

What if a simple counter weight was made to run them as a single blade prop.

The prop is robust enough to handle the added rpm.

I don't think 1000 will get used up that way. There is also some disadvantage to having a single blade with a blade length that is the same as a 2 blade. Generally the blade is longer. Now I don't know where the RPM vs diameter for thrust would balance out at so...maybe a handful could get used this way.

As a toy whirligig, that is a propeller-on-a-stick I like longer blade lengths as the smaller ones I have had do not lift very well, and tend to tumble and fall fast instead of floating back to the Earth. I have not tried with model airplane propellers but I would start with an 8 to 12 inch if I was going to. I would probably use a wood or a slow-fly prop.

There are other things called a "whirligig" too. Even with that I think the BEST answer is to recycle them after cutting a blade off if they are really defective items that risk damaging an engine.

(I have done inventory control, field destroy, manufacturer documentation, general pain in the rear...)

The issue is that we got the whole shipment replaced by the vendor and, from a moral perspective, the only option is to donate them to a cause; which includes the condition that they are not to be used for resale for their intended application. Also really don't need potential claims of "warped props" for something that we did not sell.

Donated 1,000 to our local Salvation Army for their crafts department but still 1,000 left. In the meantime, I have an idea

Melt them all down and sell it as modern art!

Most of the crap at AxMan surplus ends up being repurposed, no different than what a craft store would do with them. Just let them know that they are a defective product not suitable for its intended use. Their stores are filled with crap similar to this, overstock parts, leftover parts from discontinued runs, NOS stuff, defective parts or parts that don't meet QC... They have warnings on some things explaining why they shouldn't be used as its intended purpose. Its a store that I bet most of the guys here on this forum would like to dig through.
anyway...since you don't want to do that (I can see your point where someone may attempt to use them on an an engine and you end up with the complaints), I have a few ideas.

•Could cover a table with them and then seal and even them out with bar top epoxy (I think this would look cool).
•Could sell Cox International hats with one attached to the front of the hat.
•Could drill extra holes one in each blade and string them all together to make a floor mat (this too would look cool).

I'll think of some other ideas.

Now, let me know if you ever have any misfit .010 props, I have an idea for those!

We would be happy to donate them if someone knows of someone that can use them. Shipping cost to the USA is $25.

Bernie, I'm about to order some PeeWee parts from you.  Would you consider dropping a few into my order for my grandson to play with.  He's absolutely smitten with propellers - loves 'em!.

How about designing a little    weathervane/wind-direction indicator that would fit over a user-supplied pin on a post.. or table-top base, for at the flying field? Put    decals on the sides of the rudder.

Thanks for all the suggestions guys and the props are now off the table. Dinsdale, reply under separate cover.

So, did they pay you for them?




I was snooping there today when I spotted a box of these! gee...I wonder where they came from?

Admin- thanks for the link,  didn't follow it the 1st time you posted it, went back to check it out after you posted the pic of the props. What a riot that place must be.
LMAO reading the product descriptions. Check out the "Toy Soldiers" in toys and trinkets. To funny.

Yes, a dime each with the caveat that should not be sold for their intended purpose.

Our city hosts a large manufacturing plant for railcars.

At the end of a contract, astounding amounts of surplus fasteners, materials etc are simply THROWN AWAY.

Example: 100 piece count boxes of 6mm x 100mm Phillips head stainless screws.

Not so much for liability reasons, but because it is not deemed cost effective to inventory these items.

They would just repurchase the same items for the next contract after dumping perfectly good supplies.

Go figure!

I was just curious if you got something for them as I thought asking 75¢ each for something they got for just the cost of shipping was a little on the greedy/high side. They had a post-it-note taped to the bin that said "defective model propellers...75¢ ea.".

I'll bet most of them will end up in art projects or used on the little electric motors they have.

ax man is a interesting site, check out the descriptions like the toy soldiers--- or better yet the jock straps...to funny


In thier FAQs :

Can I use your restroom?

You're on the internet, you don't need to use our restroom! If you're talking about our retail locations, the answer is, sadly, no, there are monsters down there and we don't want our customers being eaten.

No, I do not believe that retailing them at 75 cents is greedy. The marketplace always regulates itself and, if pricing is too high, they simply will not sell.

Compared to the prices of other propellers and fan blades they have for sale, these props were in the higher range. Its one of those places that usually price stuff according to what they paid for it, not what it's really worth or what it retails online and elsewhere. Its not a bad price, just wondering where they got "75¢" from.

I must admit to being of the opinion that it's no business of any one else what business decisions Bernie makes.  They were deemed unsuitable for use on working model aircraft so he made a decision.  How is that any business of ours?  He's in business to make a living, not as a charity organization.

Been there, done that! Can you tell?

I have one of those props sitting right here, I bought a few anyway to mess around with. Now that I have one sitting here, I almost wonder if they would make good pins (hat pin, shirt pin). They're right at that limit where they are big but possibly small enough to work as a pin. I'll have to go pick up some little pins and fit them to the props, see how they turn out. I was thinking .010 props would be best but maybe these will work out.

The props were not suitable for their intended purpose and would normally have been scrapped. However, we got $100 for them and I'll be taking my staff out for dinner with the proceeds

Let someone else sell them, piece by piece, for craft usage. It may take them years to do so   and any profit they make is perfectly well-earned.
