Assembled headstock, rebuilt Honda forks, and mounted on the headstock support on the jig.

Profiling the tubing.  The use of a 5" grinding wheel in a milling machine is probably not recommended, but it did the job.  Also shown here is the holder for the 1" tubing and profiling in the milling machine.  Angles up to 45 degrees and easily done this way.  The shallow angled joints are more difficult and must be done very slowly or the milling bit will catch and bend the leading edge of the tubing.  Some filing by hand was done with an 8" half round bastard file which is 1/2" radius.

First tubes are bent, profiled, and offered up to the headstock and rear axle flanges.  Alignment of tubes was done using 2" x 3" lumber which was drilled in pairs which were bolted together at their centers with a 1/2" bolt.  One inch holes were drilled through the parting line, and the two halves were then bolted to the fixture and spaced the lower tubes at their proper height and width.  Similar pairs of 2" x 2" lumber was used to make clamps to support the suspended ends.

Rear down tubes are added.  Offset of motor is evident in one third photo.  I also added some clip-ons.  The clamps are standard aftermarket aluminum type, but the standard bars were not comfortable.  The donor bike bikes supplied the correct bends and offer lots of adjustability.

Upper bracing tubes were added. Plywood seat allows trial riding position -- not very comfortable!

If you click on your most recent photos they grow to a very reasonable size. Flicker requires you to register from the link you supplied. I hate registering for anything I don't absolutely have to.

Ah, that's a good reason to not use Flickr.  I hadn't tried -- so didn't know there was a registration requirement.  I use Photobucket -- no registration for anyone but me (or whomever is the one trying to put stuff onto it).

Thanks, guys.  Guess I'll stick with what works for now.  What are you guys doing on the internet when you should be at church?

I decided to use thicker wall tubing for the crossmembers that carry the motor mounts and head stay due to stress concentrations in these areas.  These tubes are .125" wall.  Motor mount tabs were fabbed up on the milling machine to fit over the crossmembers to take the load off the welds.  Motor mounts plates are 1/4" aluminum.  The BSA also has a lower mounting bolt that passes through the lower frame tubes.  These were reinforced with ferrules welded into the holes in the frame to ensure continuity of these tubes.

Rear motor mount is the same.  A couple of photos of the motor in the frame.
