I would start by reading all the old post here_ https://motorbicycling.com/forums/diy-home-built-motorized-bicycle-non-kit.36/
and here also _https://motorbicycling.com/forums/board-trackers-and-vintage-motorized-bicycles.38/
There are so many hand built, with ton of details, and howto's go back before the corvid hit for most.

Piddled around he all day (been raining). Did mess around a little with the frame I plan on using for now. Stripped it bare and checked the joints. It's a Columbia and seems to be pretty solid. Also ran across a cylinder mock up I made a couple years ago when I was doing some casting. Probably include something like that in the build for a more authentic look. That's about it for today.. Hope to get more done tomorrow....

Nice jug casting Dave! I have a thread for just such a thing and any other work of this sort.

Did you take photos of the casting pattern?

Villiers beach cruiser

Hi all.... My mate gave me a beach cruiser which i stripped and let rust up a little. I plan to use 1 of 2 98cc Villiers engines (different years) i have. I think i will use a 20 inch rim held to the rear rim via brackets, and mount a pulley on the front and use a vintage style hand clutch that...

Thanks for the compliment Tom but that is my pattern. Never got around to casting it. But I think I may cast just the head without the valve housing on the side to use on my motor. Not a functioning head obviously,but just to get the vintage look. Put a few disks under it like I've seen online. I'll have to make it about 6 inches or so to look right. This one is 5 inches and is a little small. I cut a steel disk out with my plasma cutter but I think steel would be a little heavy. So I will use aluminum if I do it.
