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.
Work in progress--Worlds simplest clock
I really like this one.
Just the assembly so far.
Parts in dxf and pdf to follow soon. (no kiddin, a coupla days tops.)
Added pics of a clock rescued from a garage sale
The gravitational constant has been corrected to show 9.8m/sec/sec on my website.
Thanks Mike Bedard.
from Mikes e-mail--
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.
Added James Feather to picture gallery
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
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

Repaired files to run on Netscape 4.6.
Discovered that line-height: 110% command caused pictures to paste on top of text in NN4.6
FYI: One of the neatest pages on this site requires MSIE5.5 or better in order to work.
This is the page where you can manipulate the 3D cad model.
Last time I checked MSIE and Netscape browsers were a free download
Added executable e-drawing for win 95 users and Netscape
Discovered that Volo-View Free Version will not print full scale
Added Link to Cadwizz that will print full scale ACAD files.
Added executable e-drawing for win 95 users
Removed redundant " from mail to link.
