- How To's
I don’t think I’ve thought about using a rock tumbler for about 30 years, but I heard recently they were great for deburring CNCd parts. I found an affordable one and I just started experimenting. My first to attempts have been pretty good, one of aluminum one of delrin. The parts feel great, all soft edges. Now I need to work on the polish.
I started co-teaching a toy design class. Our first assignment was to create pull string puppet toys. I started with some cardboard prototypes until I got the scale right, then I turned it into a robot. I pulled the design from the Noun Project (thanks Simon Child).
I took a show making class the other day and I’m kind of fascinated by the process. I learned how to properly measure my foot and where I apply pressure (apparently I don’t use my pinky toes). And technically I could make custom shoe forms - called lasts - for my feet. I bet I could CNC one of those bad boys.
My 2×4 enclosure project was posted on the Make: blog.
Been experimenting with some off-the-shelf metal gears. Created a couple of gear boxes using laser cut acrylic panels and some standoffs. Pretty solid to show off simple mechanisms.
I snapped a drill bit while drilling the cord hole on the last Big Crack Lamp. Half of the bit was really stuck in the wood and I needed needle nose pliers to get it out. I couldn’t find any at the time, but I found many pairs of old rusted “regular” pliers. So a little effort on the grinding wheel and I had the right tool for the job.
