Me Too, I do not normally balance propellors on the majority of my aircraft unless it is called for by excessive vibration. I do however for some of my higher performance or competition airplanes and a few of the bigger ones.

My first post was somewhat 'tougue in cheek' but I Have somehow hung on to the little razor blade in a balsa block balance widget well a long time.

I do have others including the magnetic, The Sig CG, prop balance kit was interesting that I put together when I was recuperating from some medical problems and it was a pleasant diversion that I could do in bed and a building board. it does use the wheel type and works well but with some difficulty due to the clutter of the airplane balance device portion.

In the Picture second from the left is a wheel type that I have no clue as to its origin since it came with a 'buy out' and the one that I use the most when I choose to balance a prop since its quick and easy on a shelf. Anyone know what it is?
