Hello, I am Walter and I am addicted to making things!

Walter Anderson

Middle aged male with a life-long interest in making things. My personal interests include; amateur radio, electronics, entropy, history, mathematics, metal working, painting, photography, programming, science, science fiction, and wood working.

I worked as a Transportation planner with an emphasis on modelling and analysis. I have had a couple of members ask me what that is, so I dredged up this photo I created a while back for a proposal cover that I think sums up my industry...

Jump Ring Maker

Somewhere around my tool collection I own a manually turned jump ring maker that I was planning to donate to the new jewelry interest group; however, I could not find it. While looking for it, my old dividing head that I built for my Taig Lathe (no longer own) popped up. I have kept meaning to take the worm and worm gear off of this and just toss the rest, but as I started to do that I realized this would make a fantastic jump ring maker. The dividing head had a 30:1 gear ratio, so if you drive it with a cordless drill, you get a nice slow constant rotation. You can control the feeding of the wire with one hand while pressing the drill trigger with the other. It has plenty of torque so it should be able to handle reasonable sized wire, and it is slow enough that even small wires should be easy to control. The only modifications were to remove the brake bolt, the dividing plate, the index arms and to create a new worm spindle that could be driven with a cordless drill. All that took about 20 minutes (my favorite kind of project).

Dividing Head for the Taig lathe - This was one of the very first (and first complicated) machining projects I ever did. I used it to cut gears for a small machine I was building on a taig lathe
