I’ll be performing Roue Cyr pretty soon! A total of 8 shows over two weekends at the 418 Project in downtown Santa Cruz, California. The show is a fundraiser for the dance studio called “What is Erotic”. I’m doing a piece where I’m Tarzan in the jungle taming a wild wheel. Come check it out, and buy tickets! http://www.whatiserotic.net Ken Adelman and Portia did the photo above for their flyer. My head is under the “is”.

Over winter break I started on a project I’ve been wanting to do for a long time. A coffee cup stirling engine, made from scratch based on plans from Jan Ridders. It “almost works”. The bearings seem to be too big, and the shaft has a lot of slop. I had machined the shaft to the side I thought the bearings were going to be (3mm), but they are larger! I need to remake that part and see if it works. Some work in progress shots. Power piston (graphite), cylinder (brass), crank shaft (steel), flywheel (alum), stand (alum in brass).... [read more]

I finally got some more metal and time to work on my V36 unicycle frame. I removed a triangle support that I had added to try to reduce flex, and brazed on another tube that goes up to the seat post tube. Here is the tube taped on before I brazed it: And after: This totally added the strength I needed to prevent flex from side to side. In the above picture you can see the disc brake mount I “fabricated” from a piece of steel. I stuck it on the brake, and takes it on with the MIG welder... [read more]

I’m working on a V-Frame 36’er unicycle, called the “Corbin V-36“. It’s partially an experiment to see how light I can make it, yet still be strong and not flex. I did a 3d model in Sketchup, and printed it full size. I then machined a jig to hold things in place. Here’s a video explaining the jig: And some pictures. The jig setup for my my main seat post tube: Experimenting with bending: I’m using cro-moly tubing, 1/2″ OD by .049 wall thickness. It is too small of tubing, and the frame flexes when going up hills. I’m going... [read more]
