Prop duplicator.

Maybe part of a CNC paint machine to spray the red maple leaf on Canadian geese???? Hummm?

also known as the cobra chicken.

Prop duplicator?

Prop duplicator?

As Don would say: "ding, ding, ding"!

It works well, just need some lighter springs in the follower and scribe tubes, should post a vid of it later...

 

[Terry Keeley]

Sure beats guessing with masking tap or whatever!

Really nice and easy to use......congrats.

Terry,

Nice machine, the only problem is you have the wrong propellers
on it to set current records. Great idea though! See you at the end
of the month in Flint, Michigan.

Updated post:

Don't get me wrong Terry, Octura Propellers have set more records in model boating

than any other propeller manufacture out there.

It just seems that a lot of the most current records are being set with ABC Propellers.

Thanks For Sharing Terry,

Terry,

the impression of a propeller blade by molding is it not more precise ?

Then how do you transfer that to the blade you're trying to copy?

 

[LohringMiller]

Just add a ball end mill on a flex shaft grinder with a matching ball follower on the other stylus. You now have a tracer milling set up. That should give you a precision duplicate of any propeller. You can pick the best blade on the master and get nearly identical blades on the duplicate. Naturally the duplicate needs to have some extra material for machining.

I wax the propeller to copy, after I take the imprint of the blade with polyester putty, once the mold of the blade cut off, I apply it on each blade to copy and trace the outline, I put a photo a little later

first, I modify a blade, then I wax and make the mold of the modified blade, then I apply the molding on the other blade stock to trace the modification to perform
