Since it is getting dark earlier now, we actually went inside by about 7:00 after a little parking lot action. Including another pre-meeting visit from Ed Honton and wife Melodee, on the Counterpoint-style Bilenky tandem. This time with a “For sale” sign on it.

Lance's "Kraffty" MWB
?????? passed around an unbelievable piece of industrial sculpture made with a stereo lithography machine that follows computer instructions to build up virtually any shape 0.0001 inch at a time by photo-hardening selected areas at the surface of a plastic solution bath. It can also set layers of a water soluble material that can be removed later by running the finished piece through a dish washer, so you can make temporary support structures or leave gaps where parts need to slide against each other. The result in this case was a single piece of plastic containing twelve gears that mesh with each other and all turn when you turn any one of them! It had nothing to do with bikes directly, but stereo lithography can be used to prototype (or make male mold parts) for just about anything you want, including weird bike bits.

Dave's Trail News and LWB Upgrades

Greg's Homemade Head Lights
Joyce Abel, a new recumbent rider (on an EZ1), recently returned from her first long bike tour. This was an American Lung Association fund-raising ride around the San Juan Islands in Washington that covered 150 miles in three days (plus a number of scenic ferry rides to connect various legs of the route). She had a great time and recommends Lung Association rides highly, but the shipper has yet to return her bike and she did have some teething problems with it.

The ride was too hilly for her on an EZ1, and people recommended that she take more time to get acclimated to a recumbent before such an ambitious ride and that she might want to cut the weight down by substituting aluminum parts for steel (eg. handlebar and seat frame) or cutting down the steel parts (eg. seat mount). Carl and Mark both vouched for how much weight can be pared off this way. Her gears are original equipment, which should be adequate for most climbing.

She had an un-nervingly bad front end shimmy coming down hills, occasionally having to get off and walk downhill. We can't be sure without seeing and trying out the bike, but candidates for causing this problem include an out of true wheel or loose headset bearings. It turns out Joyce also has to ride with her back bolt upright because of a neck problem, which Mark fears would put her too close to the bars and contribute to rider-induced oscillations that are very hard to consciously dampen. We offered to help with her problems as soon as she gets the bike back.


Todd's Barefoot Pedals

Denis Diekoff brought a BikeE fitted into a golf bag, for airline travel. He had to cut a few inches off the tail of the frame.
Trail news.
It was reported that the bike paths around both Lake of the Isles and Lake Nokomis are finally being repaved. A significant part of the Isles trail is even done now.
Mark Stonich had some follow-up news on the White Earth Reservation school shop project that Jetty St. John got grant money to fund. He will be going up for a few days each month and is interested in others who would be interested in going up with him on a more infrequent basis for company and miscellaneous help, or for more ambitious participation in the program if they wish. Mark plans to bring picture albums, lists of web links, and some bikes to whet their interest. His first visit is October 21-22, and he should know more after that about just what the situation is up there, what tools or parts they need, and what their interests are.

Carl can provide copies of the Tour Easy plans if that seems like a good way for them to go. Mark thinks ice racers might be an ideal project for Northern Minnesota, especially if they succeed in getting other reservation schools to join in this project that could compete with them in the winter (with the winner underwritten to come down here for our world championships in late January?). He says the was a very quick project that pretty much anyone could reproduce.

Jim Black showed a few miscellaneous goodies he wanted to sell:
1. A Jon Nygren-style tailcone of black coroplast.
2. An extra hydration system backpack.
3. Most of a donor wedgie frame (though the down tube is cut too short for a Krafft style MWB).
