Hello,
I want to build a minibike from a 2 stroke pocketbike i have, becasue the pocketbike frame is cracked and i always wanted to build a minibike, so this is the perfect oppertunity to build one. Imma make the frame for the minibike out of 20x30x3mm mild steel rectangular tubing. Because i want to build the minibike with full suspension i have to make a rear swingarm. On the pocketbike the stock swingarm was beeing held in the frame by a bolt, so it can freely move (the pocketbike sadly has no bushings in there), on mopeds or motocross bikes (higher quality than a china bike) you have the rear swingarm mounted in (i think its rubber) bushings. I dont have any rubber bushings at home, so i want to use two 20mm bearing blocks i have laying around instead of bushings. Can i do that?
My idea would be to make a custom rear swingarm and weld a 20mm shaft onto it that will sit inside the bearing blocks and be bolted onto the main frame (not like on the photo that is shown below, i think you all will get what i mean)
Those are the bearing blocks i mean:
And those are the bushings that you find in mopeds:
This is the part i mean where the bushings normally sit in:
