i got some scooter bar pieces and welded them and accidentally got a tube that was the wrong thicknessi only need to remove the extra metal for about 1 1/4 inches into the tubeany ideas will help
A latheNo access to a lathe? Use a hand drill with a sand roll, a drill press with a hole saw setup the same size of your tube going in (dangerous needs good clamping), Dremel tool with sand rolls or carbide burrs.
