Here is where I am as of today. My parts came in last night so I built the axle with bearings, hubs, and sprocket. The tires took a long time to mount on the wheels. I think they look good.
Started on the hybrid handle bars. I cut the original bike handle bars because they did not fit for this. Sleeved the center raised part, and bent new longer ends out of 7/8" 14 gauge tube. I will trim the outside handle area to fit after I finish TIG welding them together.
I clamped the bearings to the frame to see how it will look. I will not drill the holes for the bearings until I get my engine and make my mounting plate. I built a jig last year to cut the slots for the engine plate with my plasma cutter - I have made 3 already and it works pretty well.
I have a few issues to work out. Brakes, new tire, engine and engine mounting plate.
If you are looking for some part information:
40" x 1" gokart axle, keyed and clamped wheel hubs and sprocket hub.
Sprocket is 60 tooth, for 35 chain.
Wheels are 7.75x5
Tires (used) 11x 7.1x5
1" pillow block bearings
Hey OND - thanks for posting that picture. I get ideas from every drift trike I see. The scratch-built are all very different!
