Trike Progress Update July 28th

Not having enough choppable bikes in the garage to build two trikes, I had to buy a few bits.

Each trike requires 3 head tubes and 3 bottom brackets, for a total of six of each of those to build both trikes. I settled on buying 4 of everything, and scrounging the other two.

There's still plenty of manual labor to do, including building a couple of fully independent tandem transmissions from a couple of scavanged bottom brackets and a bit of an old steel crank arm!
Some free bits + welder + 2 $6 freewheels sure beats $220 for a DaVinci tandem transmission.

Spent a couple of hours in the garage building part of one of the transmissions, which brings our total to 15.5 hours.
