After I had the swash plates made I want to test out the geometry and make sure everything is going to work.

I designed a prototype fixture to test it all out.

Good thing I went through this exercise because I learned where I actually had to put the anti rotation device, 90 degrees from where I assumed it should be.

Here is a video of the working test fixture.

Wow...nice.

Seems the left assembly "pitch" is faster than the right.

Maybe the camera angle?

There is an adjustment for that in the software. It will all be adjusted later when the mechanics are finished.

I finalized the mechanics design for the control servo layout and side frame spacers.

Finished making the side frame spacers today out of 6061 aluminum. The main shaft bearings fit perfectly

Nice design work and machining!

All helis and planes have an expiration date stamped on them...you only find it after you crash!!

Thanks Barry! When I was in trade school the CNC machines were programmed using punch tape, LOL. Fusion 360 has great CAM software with all the post processors for a ton of machines and machine software. I just recently upgraded the stepper drivers and switched from Linux CNC to Mach 3, its so much better.

were programmed using punch tape,
My early computer programing was paper tape or punched cards in the distant far far past.
Really impressive work you are doing here, I am learning new stuff from you, thanks for al the detailed drawings and vids.
Hope to follow this to a successful flight.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Thanks, its has been a big learning experience for me as well. I haven't touched a mill, let me say in a very long long time let alone a CNC.

This is an awesome build. I really like your ability to innovate and implement your CNC machine into building the mechanics. I have a large vertical mill that I am thinking about converting to CNC and your posts have pushed me closer to pulling the trigger on that project.

I have always been impressed with the Kaman helicopters. True workhorses. I talked to a pilot out in Aspen, CO one day when I was waiting for my pax to show up, and it was very impressive what that heli could do. He was setting some sort of a communication antenna on top of one of the nearby mountains.
