This is how I done rear drift trike wheels. It is verry cheap way to build it! If you have any questions ask me in comments ! Dont forget to press LIKE and SUBSCRIBE !!!
In my case this is pedal trike, but if you do motorized you need to buy another 2 special holding bearings (bearings with holders, with holes in sides for screws)
0:17 - 0.4inch 0:22 - 6in 0:43 - 4.3in 2:02 - 1.8in. But that is doesn't matter all measurements i used what i have and you can yous different measurements, more wide wheels and so on measurements is not so important its the idea and example. Good luck with yours project :)
This is laminated wood panel and pvc pipe. But you can use any wood i used that because i have but there is no matter what you use, you can just simple wood planks.
Step 0 - lathe is not necessary, it just makes ride smoother and if you take your time to drill hole perfectly in center it will be even better than smoothing with lathe
