Pickering governor in 2 inch scale

<< < (2/3) > >>

gbritnell:
Thanks gents, Anthony, the problem is once the springs were soldered into the top and bottom collars they weren't allowed to pivot at their imaginary end point, almost like the spring need to be rolled into an eye at the top and bottom and then a pin put through it to allow it to swivel. The original governor that I copied is built with the springs rigidly attached to the top and bottom collars, the only difference being that the spring arms are 14 inches long so therefore they could flex in the middle. What I learned from the whole thing is that miniature governors are usually built with pivoting links that go from the center of the balls out to their attachment points and have a preload spring between the collars to keep everything extended. It definitely would have been nice to have it functional but in years of building miniatures I have found that certain physical elements don't scale down well, centrifugal force on a miniature flywheel comes to mind, so live and learn.

I'm looking at the the first 7 pictures and I'm thinking that this is pretty good work. Then I see picture 8. Is it possible to make parts that small? Or is George a counterfeiter and starting to make over sized pennies. Either way, excellent work George, this is absolutely amazing.  :ddb: :ddb: :ddb:

Cheers  :beer:

I have a distant memory of dismantling an old wind-up portable gramophone contained in a leatherette-covered metal box about 1'6" x 1" x 9". Its clockwork motor had a governor with three rather nicely egg-shaped brass weights mounted on flat springs about 3" long. So it should be possible.....

It's great, George.  A lot of beauty in such a small mechanism.
The brass looks to have satin finish.  Is it some kind of treatment, or some fine wire wheel work?

Very nice, all said.
