Oct 12 Update

Happening tomorrow:
I will be at a sustainability class tomorrow from 9am to 1pm, and possibly at an appointment until 2:30. It doesn't look like there is anyone else to run the shop so that's when I'll open.

Today:
Thanks to Amanda for coming to work her regular Monday hours. She went through the list of board member candidates to let them know about the upcoming meeting Next Tuesday Oct 20 at 6:30 pm in the shop. Refreshments will be served.

While Amanda watched the shop I took off to run a couple of errands. First I stopped at Ace Hardware to pick up the pulleys I'd ordered to put on the generator. They seem to work OK, but it looks like they'll wear out the tire too fast. The 3/4" bore size is also slightly too big for the shaft. Tomorrow I'll see what it costs to bore them out, and see if it isn't better to have rollers made from scratch. If anyone reading this has a metal lathe and would like to give a quote on making them please let me know. Also looking for a watt-meter.

This evening I took the bike generator down to Wamsley Cycles to show Chip. If you don't know, Chip fills his Winter hours by repairing exercise equipment including treadmills (where our motor came from). He took a look at our (puny) motor and then took me into the back to look at a REAL treadmill motor. I can see why we're getting these things so cheap! They're still way overbuilt for our (re)purpose though. Voltage is another matter. With a 2" pulley running against a 700c tire we get only 100V no-load, and it dropped down to 60 when powering a drill. This means we're going to have to get a smaller roller somehow to get RPMs up so we have 120v under load. Any ideas are welcome. Turns out 17mm bore pulleys with 1/2x13 tpi threads are pretty rare in anything except treadmill flywheels - which are way too large.

Today was move-in day for the new Mountaineer Station - the multi-modal transportation center (public grand opening next Mon Oct 19). Hugh Kierig was just walking up the drive when I arrived so he gave me the tour of the bike parking facilities. First was the VERY spacious shower room, with room for a changing bench and clothes hooks - everything we recommended. Then we looked at the space for the outdoor racks (10) which will be covered and far enough back under the roof so that bikes are mostly shaded from sun and weather. Finally we made it in to the indoor bike room. Again it looks like everything we recommended has been put in place. A monitored (24/7) security camera has been installed so there is no need for access control on the door. It will be left open at all times (unless there are problems, at which time other options will be considered). There will be hanging racks for 18 bikes (now being installed), plus lockers for storing gym clothes and dress clothes separately. There will be an air compressor just outside the door next to the handicap spaces for inflating tires. In addition I recommend that a vending machine and small work area be provided inside the bike room for emergency repairs, as in the Seattle (and similar) Bikestation. Pictures tomorrow.
Come see the Grand Opening next Monday if you can!

Expenses:
$16 for pulleys a 2" and a 3" with 3/4" bore. We'll be returning them to exchange for the 2" ones with 5/8" bore so we can turn them out to 17mm.

That's all for today.
Nick
