I'm building a kart for my son and the rear suspension will be some sort of IRS setup. I'm going to use a quad rear bearing carrier for the sprocket and brake, then weld 930 drive flanges on the axle (cut axle just past the sprocket and rotor). Doing some quick measurements it looks like I will have short axles to keep the track width down. I don't want to spend a fortune on having custom axles made. Do you think I could cut a few inches out of an old axle weld it back together? Cut the axle nice and clean, chamfer the edges, lay axle in a "v" block and TIG weld it up. The motor is going to be a Yamaha 350. So there isn't going to be a ton of power.
