Simplicity by Karl Noren
I'm a newly retired electronic engineer; my main hobbies are Fishing and Woodwork. I purchased your plans for the Simplicity Clock to fulfil an ambition I had to make a wooden clock movement. Once I retired and had the time available for such pursuits.
I found your plans very well worked out and fairly easy to follow, (after converting your inches to metric) the clock is now finished and hanging on the wall and keeping good time.
I made the big cog wheels using plywood but the rest is made from a local hardwood, Jarrah, (see link) it is my favourite wood and I have made several pieces of furniture over the years. If I get around to making another clock it will be all Jarrah but I can't get Jarrah plywood so I probably have to do my own laminations.
I got the clock to run OK on about 4 lb, I settled for a weight of 5 lb 3 oz, (to give it some reserve power) lead enclosed in a cylinder made from jarrah, I had to reduce the length of the pendulum rod by 2.5" to get it whitin range.
Aloha Karl, you have created an extremely beautiful Simplicity. I can understand why the Jarrah is one of your favorite woods ~ it's color and depth and overall appearance is spectacular!
I think you have created the first Simplicity Dial Ring that is rotated an additional 15 degrees. It looks wonderful with the inlayed dots and spaced separations. Brilliant!
Your final drive weight is perfect, too. Since the Simplicity is a beginner's clock, my drive weight recommendation is way high. I put it up there because I want every builder, no matter their level of craftsmanship, to be able to hear their clock tick. The drive weight you have attained is a testament to your craftsmanship...as if one couldn't see that throughout the rest of your clock. You've done a truly spectacular job on your first clock(!)
For solid wood wheels or on how to lay up your own ply wheels, check out the "Ron Walters" link in the "Favorite Links" section of my site. He has done some superlative work with solid wood and homemade ply wheels.
Thanks for the beautiful pix and for doing the Simplicity plan so proud.
