Jordan and I picked up some 1/2" EMT conduit from the Home Depot and visited Bil at Aerotecture yesterday. Bil sold us 6 lightly used square-flange mounted ball bearings at a very nice discount. We weren't able to use the bender at Aerotecture, but Bil suggested that we try Chicago Metal Rolled Products to coil the conduit for us. Chicago Metal worked on Bil's earlier turbines, before he got his own bender. They also created the curves in the roof on the Ratner Center at the University of Chicago. If you ever need to get some metal rolled, go to the guys at Chicago Metal - they were the most pleasant people to deal with and were kind enough to do the work for free. Ziggy was going to do the coiling, but one of the five Stanleys ended up doing it instead. As you can see from the picture, the coils were perfectly rolled to a 1.5' inner diameter.

Other materials: Last week we picked up a 4' x 8' sheet of 0.093" Lexan from Piedmont Plastics who also gave us a discount. The Lexan will be used to fill the gaps between the ribs.

Nuts and bolts from McMaster should be arriving on Saturday morning, so hopefully we can start putting some things together over the weekend.
