« Part 1: The Plan Part 2 of Simplicity Wooden Clock series Part 3: Yet More Drawings... »

So, after what feels like months, I was able to do something in the woodworking arena. I ran over to MacBeath’s in Berkeley, CA and grabbed some quality plywood. Then I came home and drew up almost the entire clock in AutoCAD, measuring everything very carefully on the original plans with digital calipers. The point being, instead of gluing the plans to the plywood, cutting them out, hence destroying the original plans, I’m going to have a fellow LJ cut the gears out of the plywood with a laser. This will allow me to keep the original plans and the gears will be perfect. I can also make a second clock for some friends’ wedding present with very little duplicated effort. It took about five hours, but I made all of the gears and the hands. I’m hoping the end result is accurate. Here’s the main gear in the center of the clock face:

They’re all on different layers, centered at 0,0, so hopefully, my buddy will be able to cut out perfect shapes from 1/4” plywood, them ship them all back to me with a minimum of effort on either of our part. The 1/2” pieces will be two layers of perfectly cut out 1/4” gears. I’ll let you know how it turns out. Here are the hands:

I really like the look of this clock. It’s very gothic. If this project works out, I’ll be purchasing the celestial calendar plans. Here’s the hour wheel:

P.S. I have no idea if what I’ve drawn will end up working. I’m sure it’s very close, but not 100% accurate. I may very well just have to spray adhesive the plans to some plywood and do it old-school…

I too use Autocad for drawing most of my plans. A few hours in front of the computer can save hours trying to figure stuff out in the shop. I’ve been toying with the idea of getting laptop and put cad on it. That way I can make changes to the plan right out in the shop, saving some time.

It will be neat to see how this turns out.

My girlfriend got me a little notebook just for that purpose (which is what I use to peruse LJ over coffee). I didn’t want it to be exposed to the sawdust, so I leave it just inside the garage door. It’s also great for cooking online recipes. It was actually pretty fun drawing up the gears. It reminded me a lot of my Mechanical Engineering classes, but that was twenty years ago…

I forgot to mention that I got white oak and walnut plywood, so the various gears can be made out of contrasting woods.
