The plans are from ScrollSaw Woodworking & Crafts Issue 42. This clock is not a traditional clock. In this clock the numerals for the time are not on a ‘stationary face’ but on the gears (the hour wheel and a minute wheel) themselves. The clocks hands don’t move. After making copies of the plan I cut up the plan according to stock thickness and type. There is 1/8, 1/4, 3/8, and 1/2 BB plywood and well as 1/8 and 1/2 hardwood, I'm using cherry. In the past I’ve had issues applying patterns to wood. Either they come loose while cutting or fray so lines can’t be distinguished and/or are difficult to remove. So after checking with a couple of folks on another forum I decided to try covering the face of each piece of stock with ‘blue painters tape’, adding the pattern with 3M adhesive and then covering the whole thing – front and back with packing tape. This seems to work pretty well but I’m not thrilled. This project has a lot of drilling and I sure wouldn’t attempt it without a drill press. Drill bits needed are 1/16, 7/64, 1/8, 5/32, 11/64, 3/16, 7/32, 1/4, 17/64 – yep, lots of drilling. The author recommends using brad point bits. I’m not even sure they’re made in all these sizes and even if they are, I’m on a fixed income so I used plain old twist bits. I applied the patterns as described and then using the center hole of each gear and a circle cutting jig on a band saw to cut out the circular shape each gear. Then I used the same jig and disk sander to get the edge just 'kissing' the top the pattern of each tooth. However if the center hole isn’t drilled exactly in the center of the pattern, when using the circle cutting/sanding jig, you’re off some. I think you can see this in the pics. In order to position each wheel for the drilling I used the scrap from the circle cutter and clamped it to the table so I could just spin the wheel to each new location. I could get pretty close using that method. Then bring the bit so it’s nearly touching the work and move the gear exactly under the bits center and clamp the wheel into position for drilling. Because the bottoms of the “valleys†between the teeth seemed round I decided, rather than scroll them, I’d drill them out. That’s what I did. Then I scrolled from the top of each tooth to the center “valleyâ€. It seemed to go pretty well. The author recommends cutting just outside the line and then using a strip sanded to creep in and just remove the line. Unfortunately a tool I don’t have so I’m hand sanding quite a bit. The plans have a set of numbers on them that are to be mounted on 1/8†stock and then scrolled into a ‘shield’ shape and glued to the wheels. This ‘glue the number’ process wouldn’t provided a look I was happy with, so I looked for alternatives. I could print out a new set of numbers and then try to transfer inkjet images to the wood wheels. I could try wood burning. I could go to CL and find a calligrapher. There are rubber stamps, stencils and paste on numbers. I ended up purchasing a set of rubber stamps (Garamond type) and added the numbers to the largest face. I made a little jig that helped my position them and used acrylic paint. (Sorry no pic but I can post one if someone has an interest.) When I went to add numbers to the ‘minute face' my stamps were too large. Agh! So after some trials I ended up using the computer to set the numbers I needed, reversing them with Paint, printing them out onto Jolee's Easy Image a product used to transfer (ink jet) computer art to fabric. The transfer is done with an iron. But it seems to work okay on wood. One of the worst things is that unknown on a project like this. I've taken quite a bit of care here but I have no idea if this will really work. Are the teeth well enough formed? Next step to cut and polish the arbors. I also still have to cut the pallet and get weights. (POST SCRIPT ONE: I know I ‘talk’ a lot, my wife says I never say anything with one sentence that can be done with 5 or 6. Those bored by the narrative can just look at the pictures. POST SCRIPT TWO: In Previewing this the photos are all small. I'm hoping that when posted you'll be able to double click and get them to a more reasonable size. If not I'll have to get another lesson from Admin.)
