Making Handlebars For Your Scooter
If you would like to make some strong one-piece handlebars for you scooter there are a few things you are going to need:
-tig (recommended) or mig welder. or someone who can weld it for you
-4130 chromoly handlebar = [link]
-4130 chromoly steer tube = [link]
-drill/file and temple to make a hole/notch in the steer tube so the tubes will fit together snugly
-a jig to keep the tubes square during welding
now just get the tubes, notch/drill the steer tube, put both in the jig, and weld them together.
