Close. It's a Sherline lathe.

The little chop saw is a huge improveme nt over the Dremel hand tool. I got a 1/16" abrasive cutoff blade for it which will outlast several tubes of the Dremel cutoff wheels. It's great for cutting brass and stainless steel for arbors and bushings.

It's the brass pawls on the Sextus winder drum that I noticed.

I was afraid that they would be too fragile if I made them out of wood so I used .250" brass and a .0625" router bit. I used the same brass for the ratchet wheel. It cut very nicely and gave a very good finish.

Wow! That's really a nice piece of work.  When I have a clock on my work stand I often want to mount the pendulum and so I need a meter clearance under the clock - does your stand allow for that?

Yes, generally . It really depends on how you build the mount and how far back from the edge of the bench that you mount it. It will also depend on where on the clock the pendulum mounts. The center of my swivel base is mounted is about 12" back from the front edge of my bench. With the clock placed verticall y out past the edge of the bench, I have 64" from the top of the pendulum to the floor. However, the pendulum mounts right at the top of the frame on this clock. The bottom of the clock frame in the picture is 45" above the floor.

If in doubt, just make the extension arm a bit longer and / or mount the swivel base closer to the front edge of the bench so the extension arm is more towards vertical than horizonta l.

Here is a pic with an old unused pendulum from an old project. It's just a bit over 39" - about 1 meter. I just hung it on a convenien t spot for illustrat ion purposes. Hopefully you can eyeball things to see if it fits your needs.

Just couldn't leave well enough alone. I added a new mounting plate option. Fewer parts, a bit simpler, and adds another degree of motion. The ZIP file is now Version 3 above.

Joe, if you go to the bottom of my first post, you will see a paper clip and a file name. That's the zip file. If you're still stumped, just email me at :
cnc AT ldrider.c a and I'll email it to you directly.

Since my last post a few month ago, a couple of things have happened. First, I've had a few direct emails from people wanting the dxf's that were getting 404 errors from the forum when they tried to download them. I was quite happy to send them and have a few short discussio ns on the project. Second, I've done a fairly major redesign to simply the project. And I created a short Google doc's page showing the pic's and construct ion details. Email me directly if you'd like the dxf's. I keep messing about with them so you will always get the most recent versions this way. And finally, please be sure to tell me how your build goes and what, if any, suggestio ns that you might have to make it better. It's been a fun project.

Nice work David.
It could be used for many different things besides clocks as well.

I'd like to suggest you consider writing an article on this for, well, I don't know who exactly -- maybe Fine Woodworki ng? Seems like there'd be a reasonabl y wide audience for this thing?

(I've just started my build, using a laser for the cutting so I'm building it up out of thinner sheets of BB ply, which is working pretty well so far. I guess we'll see when I get to the larger arm piece...)
