I've spent my whole winter build time looking for blueprints for these bikes, especially the forks. Thank you so much for posting these. Is there any chance you have any that I can read the measurements on? I've enlarged these and can't. If not no biggie, I can find a common part on one of them somewhere for scale and pencil in some. That should get me in the ballpark.

Thanks again
 
Rakkassan34, let me say this since the patent drawings don't show measurements it is fairly simple to realize the forks had 26-inch and some were 28-inch wheels.

I'd suggest that you maybe try to enlarge the drawings and then add the 26-inch and 28-inch wheels and then you'll be close enough to the original wheels.

Very nice fork design, cool shop you have there Heretic....

Wish my shop was large enough for a locomotive!

Start yourself a build thread here in the Vintage Style build section of the forum.

BTW, welcome to the forum you're in the right place for motorized bicycling.

Thanks again for posting the drawing of the 1939 Veloce front forks!

Peace Crazy Horse.
