My first recumbent bike
To the best of my memory, this was the first recumbent I built back in 1975. I made it in my metal class when I was 16. I never did get a picture of it, and I never finished it, but it was to be a two position bike either riding upright or reclined.
Read MoreBurningman trike
My first motorized trike was made for my first Burningman experience back in 2000. I used a 3 hp Briggs and Stratton motor with belt drive. This went to a 12″ pulley which drove a 13 tooth sprocket to my rear 6 speed cluster. It could easily carry 3 people, and it topped out at…
Read MoreBurningman box shelter
This was my first use of Coroplast, or better known as fluted plastic or plastic cardboard. This 2-1/2 sheet 4 ft square box used 2×2’s for corner framing. Button head screws fastened the panels to the frame. For transport the shelter was made modular. All I had to do was attach the corner frame to…
Read MoreMWB recumbent
Itching to have a test ride. Of all the recumbent bikes I’ve made, this was my favorite and most used. I later added a 3 speed wheel with drum brakes up front, then added pontoons for a kinetic race, which never happened. A minute after this image was taken everything went South. The pontoons flipped…

This was my fourth recumbent build. I built it for my neighbor kid who thoroughly enjoyed it.
Read MoreAluminum SWB recumbent bike
This recumbent weighed in at 25 pounds. The main boom was made using 2″ aluminum tubing. To eliminate stress on the aluminum frame I placed the seat mounds directly over the steering tube and rear wheel stays. The crank length was adjustable, but often the hose clamps used to secure the crank tube would fail…
Read MoreMicro push bike
This prototype was my version of a modern micro Hobby Horse. It was intended for short trips to the bus stop, train station or subway. Unfortunately the seat put undue pressure on one’s prostate area. A later version would have included a poly suspension on the rear arm, also having the steering tube and rear…
Read MoreRecycled Campaign sign shelter
This 4 ft high by 8 ft long shelter was built almost exclusively from recycled election campaign signs including the lumber and hardware. Attached to the exterior green house is a pole that holds the gravity fed solar shower bag positioned toward the sun. Rain water is harvested for taking showers. To keep…

Read MoreCoro box boat
For PDF plans, click here! The Coro box boat was a design that created more buoyancy than my first ‘V’ hull motor boat, the Coro Speed boat. At first the steering mimicked the Speed boat but then it went thru an evolution. On the next version a front storage area was included. A ‘V’ bar…
