Mini bikes and hot rods go together right. I found another project for the kids and I . I found a old minibike bare frame for 25 dollars that I want to get going for the kids. I have a small problem though. The frame seems to have got some water in the tube that supports the motor. I does not look that bad to me but will pretty much be impossible to tell over the internet the integrity of the tubes. I want to make some kind of wire brush with a extension on it to send in down the tubes and clean any rust in the interior of the tubes. Then fill the tubes with some type of rust converter/primer. Tap the cracks shut and weld and finish. I guess best would be to cut some tubing in half and weld some pieces in over the cracked area. Then I want to wire brush the frame and put some naval jelly on it to take care of the surface rust and paint. Any ideas on this project are welcomed. Thanks
