Hi Rick,
The angle of the cylinders is 40 degrees. The heads and the side plates will be removable. The heads just in case I have to and the side plates so I can get to the motor.
I started on the side plates today but gout or as I prefer to call it "The hot Foot." drove me back into the easy chair. It's let up so tomorrow looks like a good day to finish it. Then it's time to look into devising a jack shaft that can be hidden as something else.
Steve.
Hi Steve sorry 'bout the gout, but glad the weather is giving you a break.
I'll check on the fins today, really thought I'd have them by now. I'm hoping that the city fathers aren't selectively enforcing the no work ordinances that are in place for many. His shop is half a block from city hall and police department.
The exact angle isn't critical but going much over or under 40 can cause problems in what we would think of as typical bicycle frames.
I first thought I'd go with a bottom bracket location for the jack shaft transmission which is really quite sensible and the most authentic look. I also considered hiding the jack shat in a magneto look housing before locating the jack shaft in the motor case housing, which was a bit more work and created some issues that l had fun with, but I'd say the bottom bracket location will be my choice for the next e-V-twin or single. A battery ignition box or oil tank could also conceal or the most obvious would be a simple transmission housing 2 or 3 speed look for a simple reduction gear jack shaft transmission.
Re-locating the bottom bracket aft of the seat tube is seen on some old V-twins & that yields space for the larger cases. The Harley bikes, and others, really jammed the rear wheel forward and left only an inch or so between tire and seat tube, perhaps looking for rigidity, but I'd think ride/handling issues would have resulted that the rest of the bike's design had to compensate for.
Designers reasons give old minds something to wonder about instead of just wandering about.
