Seat back



I was able to shave 1 pound off the weight of the seat back with a few more holes. The seat stays and seat back are now glued in place. I also dusted off my old Wilderness Energy hub motor. Yep! hybred velomobile for less than $100 bucks. Wow!

Ugh! Sewage in my Man Cave!!!!!!

My “Man Cave” was desecrated Monday night. While I was working on my low-racer seat back in the background I heard a gurgling noise and the sound of water trickling. It took me a few minutes to connect the sounds with there possibly being a problem, I was rather into what I was doing and not thinking about too much else. Then the smell hit me. Ugh! Sewage!


Years of being an Environmental Scientist and having worked in sewage treatment plants (for only a very short time) one’s nose knows that smell. The pit where the house trap is was over flowing, and thankfully into the nearby drywell drain – this is “my” basement. I stopped working on my ‘bent and called Roto Rooter.

Roto Rooter is great. Andre, the technician they sent, was very professional, knew exactly where the problem lay, and went right to work. $350.05 later the blockage (paper) was removed and this household artery is once again clean until the next time “arterial-real-grossness” happens again. Thanks Andre!

The ‘bent is coming along fine. After I glued the main beam of the frame I realized there was too much flexing in the back support beam and seat bottom beam (for lack of better terms). I solved the issue by using the seat back and bottom as integral components mounted directly to the beams to stiffen the frame. It work, I am happy. I also realized early one I would have to add stays to take stress of the rear beam and stiffen it up a bit too.

Hopefully by the weekend I will have the frame completely glued and I can start sanding – I am getting tired of pulling splinters out of my skin.

If I haven't said so already, I love Gorilla Glue.  Except for the obvious fasteners for the head tube, the frame is held together on using Gorilla Glue.  Thanks Gorilla Glue - you're the best!

Next step is the drive train. More to come on that.

Here are a bunch of pictures showing my progress. The hula hoops are going to be used as the longitudinal members of the fairing. If you know about geodesic airolite boat construction [www.gaboats.com], you will understand my approach to fairing construction.

All in all, from only scraps and a few store-bought nuts and bolts, and using only my hand tools, I am well on the way to building a sub-50 pound velomobile.
