random thank you gift
I applied for grad schools last semester and cool people wrote letters of recommendation for me. This is the thank you gift i decided to make for these cool people. I started with a flat strip of brass. If you have a particular size in mind, you can make a quick mock-up with paper. Then […]

pF: seatpost, foot pegs
about time for an update… I was lucky enough to come across an old Brooks saddle, but it was in need of some love. The seat was extremely dry and stiff, to the point that there was pretty much no flex at all in the leather. After some online reading about leather restoration, I chose […]

Small Bike (part II)
Small Bike (part I) covered most of the front end and the dropouts. Next I worked on the front and rear forks, which were very similar. Both are essentially 2 dimensional shapes. So I cut them on a waterjet, and then used a boring head on a mill the clean up the tube clamps. For […]

Lamb Roasting
Today I made a shovel. Charles Guan and I then hacked together a lamb spit. Motor is 1 RPM synchronous, 115 V AC. Torque is a bit limited, so we will see how it works. This is for roasting a 28 lb lamb for 6 hours tomorrow.

PicoFahrrad: welded frame
I completed the welding of pF’s frame! Next post should show the assembled frame and front end. Tubing for the fork came from the chain stays of an old road bike frame. A wedge was cut from the tubing, and then it was bent and welded. The dropouts are 0.188″ steel cutouts inserted in welded […]

Small Bike (part I)

Unicycle
This is a project I worked on last semester and finished sometime around April 2010. I can’t actually ride a unicycle yet, but at least now I have one to practice with. I machined the fork structure, hub, and cranks. The two round plates holding the spokes were cut from sheet metal and are screwed […]

Introducing: picoFahrrad
This is the picoFahrrad, a small, soon to be electrified bike/scooter. I will hopefully weld the frame soon so that the mechanics are finished. The rear wheel is a 7.5″ DIA pneumatic that will be belt driven, probably by a DC motor. Hopefully the electric motor portion will serve as the final project component of […]
