Project Information
I made this first one of these last week, And I was not happy with how straight my 3 axle holes were, which impacted how well the wood balls rotated when you crank it. I posted this project on this web site, you can use this link to see it.
When I was doing a previous project, I ran across a method of making long and straight holes in wood. The method is at least as old as the early 1900s, when lamp makers cut a square groove in 2 mating pieces, glued them together, lathe turned them into lamp bases, then ran the electrical wire down the center hole.
I decided to make a 2nd unit using the square hole method, and see if the balls rotated better with improved ball axles. I made a short YouTube video of this method. You can use this link to watch that video.
I was very pleased with the square hole method, and the balls do rotate better on Unit #2. Here is a link to a short video on Unit #2 being cranked.
You can see this project on my woodworking web site using this link.
I'm going to use the square hole method on the next project where I need a long and straight hole with a high L/D or Length/Diameter ratio.
Thanks
