Prop value?

[ifdale]

Looking to sell a prop, I have no idea what it's worth. Hoping to get a ballpark idea. McCauley 1A90 71-48, reconditioned metal prop, looks to have been reworked twice..good shape. Thanks!

7-1500 depending on what paperwork you have. Tim

I'm in the market for a propeller to put on my new C85. Do you have any pictures of this one?

Re: Prop value?

I don't know if there is paperwork or not. I'll have to look. Tim I have a picture, I can email it to you. But just so you there was a guy interested in it first, I'll see if he's still interested.. I really don't know what the prop is worth.

Re: Prop value?

Is it painted or polished? polished is worth less because the alodine is removed. Are any of the numbers stamped out and restamped with a new set? If so, it has been repitched. You can always have a shop look at it and measure the cord and if the blades are coned foreward. Inspection and repitch was 250 the last time I did it. I waited for the prop guy to repitch and adjust the blades. I recommend you leave the facility, hearing the blades crink and pop and snap will cause you to never want to fly again. Tim

Aluminum can be ANODIZED or Alodined, but it is common to mix them up. Alodine is a chemical conversion coat that has to be protected by primer or paint because it is so thin and fragile. It is kind of a transparent golden color. Anodizing puts a hard coating on the metal and is a true plating process, but it CAN be removed by over polishing. You can anodize in almost ANY color and it does not need to be covered by any kind of "paints". I don't know which was used onthe prop, but if it was bare metal that was polished, you have to keep it polished or it will pit. If it was painted SOME brands allow them to be stripped and polished and some don't, but again, you have to KEEP IT POLISHED AND DON'T LET IT GET PITS! If it is Anodized you will have to wipe it down and spritz it with some Lemon Pledge every once in a while and keep it clean. A good coat of wax makes Anodized Aluminum look REALLY GOOD.

Hank, we have discussed this before on the forum and I will still stay with the FAA guidelines that polished blades on a McCauley or Sensensich does not conform to its type certificate. Also Anodizing was not approve last I talked with a prop shop. You don't want to put a hard surface on the flexible outer surface of the blade because it will cause a crack.

Hamilton standard is the only prop allowed to be polished. The others you polish and fly at your own risk. If the wrong faa person spots it he will red tag it and there you will sit. Been all thru this including having had to buy a new replacement McCauley prop. Easy to call a reputable prop shop and have it explained.

The Hamilton's have steel core blades on some models...and complete steel blades on others.

Re: Prop value?

I wasn't addressing the use of anodize or alodine on props (intentionally) just responding that the two terms are mixed up a lot and the processes are very different. There is also a soft anodize for aluminum but I have never heard of it being used on a prop either. There is "supposed" to be one make of small plane prop that can be polished but I don't know which one. I have a wood prop. ;-) I have a metal prop for the 45 that I will be overhauling before use and plan to have it painted "Aluminum" and wax it. Close enough to polished for me and easier to take care of.
