Making Propellors

[john e. holliday]

I thought I knew about how to make  propellors.  On Barton site one of the posts mentioned the making of propellors  for wind tunnels.  Go to  Youtube  and do a search on the topic "Construction of Wooden Propellors Part 1".    There is also Parts 2 & 3.  No sound  but very interesting to me.

I was impressed by how the final check of the surface came down to the feel of a skilled man with his hand.
There were some really nice tools used. Altogether very impressive
