An Interesting Procedure

[Richard SimpsonParticipant @richardsimpson88330]

Something I thought you guys might find particularly interesting.

Over the years I have worked with some incredibly talented crewmembers.  Their machining and engineering skills frequently put most of the engineering officers to shame.  One guy in particular stands out in my memories, particularly with a project I discussed with him.  I was discussing with him the possibilities of making some sort of presentation to our company President, who was retiring.  He suggested a brass model of one of our propellers on a base, which I though was an excellent idea.  Unfortunately we were fitted with what are known as highly skewed propellers, which I thought would be something extremely difficult to model in brass.

He asked if he could have time to look into it which I was more than happy to do.  After a couple of test tries to prove his set up he eventually produced this item.  When you have enjoyed looking at it and thinking about how it could possibly have been made I will provide links to some video clips that will show you how he did it.

When I retired a couple of years later he made one for me as well:

 

And before anyone with a keen eye informs me that the real ship has six blades and the model only has five, the picture of the real ship is a previous one that had six blades and I haven’t got a good shot of the last ship’s props!

Beautifully done, my son does ret gifts where he works things like 1/8 scale chassis for a well known sports car maker. all parts being laser cut identical (but for size) to the original.
