everything is always 85% done

      Knowing that I'd lose access to a really awesome workshop when I left EMP|SFM, I tried to make stuff that I knew I was going to use at some point but probably not right now. Plan B is certainly going to get a inner-rotor ignition at some point, ala ciaociao. A standard Puch flywheel weighs about a pound, a standard Vespa flywheel weighs just under three pounds. -And for a 'race' bike, thats like riding with the brakes on. Which I do enough of, already.

     If you want a ciaociao flywheel fan, you'll need a plastic kinetic TFR fan. The guys at Cosmopolitan Motors were very helpful locating one for me. You'll also need an inner rotor ignition, probably off of a smaller CC dirtbike. PVL makes some really good stuff. Just make sure its a 2 stroke not a 4 stroke. I got started by eliminating 1.5mm thick disc from the underside, inner portion of the plastic fan. I did this using lather-beams. Using that as reference, I drilled a .5" hole in a piece of aluminum, and fitted a hex bolt & nut through the hole- which is the same diameter as the crankshaft- to then set up in the lathe. I lathered the aluminum to the same diameter as the underside of the plastic fan, then took that down to 1.5mm thick. I stepped it out to then match the inner diameter and thickness of the plastic fan's hole, and also stepped another 1mm as a spacer. There is something really satisfying about the look and feel of freshly cut metal. -and I'll just let that last statement be creepy, whatevs. This project still has aways to go, but I think this is the only part that I could not do at home. We'll see.

I also made a rear wheel alignment/ adjuster do-hickey, because Plan B could use it.

       I've been screwing around with a vacu-forming rig in hopes of maybe making some transparent flywheel covers. So far I've been close but no cigar. I believe I need better suction to pull out the wrinkles. I have one more modification to try on the buck before I rent a Shop-Vac and try that. Work harder, Dirt Devil!!

        Finally, I have just moved to Portland. Thanks to basically 100% of people that I have talked to about or during the move, I am yes aware that Portland has an inordinate number of excellent coffeehouses, strippers and microbreweries. The move was bittersweet, mostly because I liked Seattle a lot, and because my career seemed like it was getting a toe-hold as an exhibit designer/fabricator. Portland is known as a design-savvy town, but unless I work for MotoCzysz or Nike I don't know who would hire me? plaid pantry?

when i contacted cosmo about getting one of them fans they wanted me to order like 100 of them or some bs.. they wouldn't sell me one for less than like a bunch of monies.
