Hi Nicolas,
I hope you and Mike don't mind me piping in here.
Thank You, for your fine design. I apologize first off, for my dyslexic model description,(GS1a), I will edit my prior post.
My father and I have built 5 Bensen/Brock style gyro's, back before much was understood by homebuilders concerning CLT, H-stabs, etc.
After finding this Forum, I got the bug again, but knew enough now to realize that the "old" style just didn't make sense to emulate.
I love the Dom., but I detest the chore of coping tubing.
Mike and I talked about what to build for weeks. We just couldn't seem to agree on the "best".
Then, you posted your video. I guess I will quote Pete, "I was gobsmacked".
I called Mike, he jumped on the forum, and checked it out. It was decided.
The basically straight Keel, beam axle, just perfect for the homebuilder.
I didn't fab a thing on this gyro, Mike has done it all and has done an outstanding job on it.
Thank You for you input also. We discussed the fretting of the mast, but there is so much surface area pinched, we think that fretting will be eliminated. But if, we figured a Cherrymax rivet centered on the mast web, low on the cluster plates.
Concerning suspension, we have an abundance of paved, uncontrolled local strips that are gyro friendly. Mike used doubled 1x2 for the axle.I think that softend tires will suffice, tho I do have thoughts on the struts.
Mike just couldn't resist using the airfoiled Chr/Mo tubing he had scrounged.
He did a fine job terminating the ends, and as Phil mentioned, if need be, the outboard ends can be moved inboard, and no evidence of the outboard mounts will remain, so it gives him options.
If Mikes interpretation flys as well as yours, I will copy you again, and scale it up for a two place.
Thanks again Nicolas for the inspiration. Good luck on your pre-rotator endeavors, that might be our next emulation.
