Revised Worlds simplest clock

Escape Wheel now made from recycled compact disc. Revised Pendulum lever efficiency. downloads

As promised part files in pdf. Holding off on dxf unless you ask real nice.

There will be other versions of the escape and pendulum parts coming soon so that various engineering concepts can be proven.

Nothing like a little reality test.

I really like this one.

Just the assembly so far.

Parts in dxf and pdf to follow soon. (no kiddin, a coupla days tops.)

The gravitational constant has been corrected to show 9.8m/sec/sec on my website.
Thanks Mike Bedard.

*************************

from Mikes e-mail--

Gary;

I enjoyed your site very much.

I suggest that you may have a very subtle error, which appears in at least two spots within the site.

You list the Gravitational Constant as 9.8m/s In fact this constant specifies a rate of acceleration (as opposed to speed) and thus the units should be meters per second squared.

I discovered this while walking through the algebra for your "length of pendulum" formula. I always carry my units through the calculations so that they may indicate any possible errors I may have made. In this case the units kept coming out as ms (meter seconds) which I knew could not be true for the length I was expecting.

Regards
Mike

Redesigned weblayout so page can be read on browsers that do not support CSS.

General update to all pages.

info on how to get free plans from Taunton Press on homepage

From Jay...........
I'm real pleased to have found your site and all of the wonderful information.
I have a comment on the .dwg file I downloaded.

There is a hole for a shaft at the top of the clock whose centerlines don't match the center of the hole.
The hole is 10.856 from the bottom edge of the frame on both the from and back.
The center lines are about .109 different than the hole.

The dimension 15.234 in the assembled view should be 15.485 due to the right side of the dimension hitting the intersection of the radius instead of the edge.

Petty stuff, I know, compared to what's right, but I thought you might be interested.

Not petty at all.

Thanks for catching this one.

The drawing is corrected and can be downloaded from downloads
