John Reese's SWB

John Reese showed a modified MTB frame based homebuilt. The main tube is only .035, but he hopes it will be adequate (Mark says at 1.75" OD it should be OK). The fork was cut shorter, re-welded, and re-raked in the Jon Sharratt style. It has no BB boom yet, and that will be about 12-14” long. He will probably run a tandem drive with intermediate shifting like many of Dave Krafft's bikes. (Mark reminded him that it IS possible to build such a set-up that will not lose the connecting chain every ride or two.) He plans for the bike to be rideable at the next meeting, and he will start working on a shell to put it in the month after that.

Head tube angle was determined in the Krafft tradition. Lightly tacking (or duct taping) the head tube in place and coasting down Brookside Ave. in front of Dave's place. Different angles are tried till the steering feels right, then the head tube is solidly brazed in place. Not the way Mark would do it, but even he admits that Dave has made some decent handling bikes that way.

To my thinking, grafting most of a bicycle frame onto a single fat tube, then adding a new head tube and BB in whatever locations you want, is a more sensible way to recycle old bike frames than building another TE clone.
1. It's much less work. Far fewer joints and when you do interface with the old frame, you are working in the middle of tubes, not at messy existing joints.
2. Most TE cloners reuse the top tube/head tube/down tube assembly. This invariably forces compromises in the steering geometry, steering ergonomics and BB location. For a clone done right, see http://mnhpva.org/meetings/Dec_01/Dwight.html

John unbrazed the seat stays at the dropouts, and re-brazed them at the new angle. Us lazy types just bend them down, over a rounded piece of wood. Also, you don't necessarilly have to add the existing frame at the rear
