i am extending an older gsxr swingarm for use in a kz 1000 street/drag bike.here is what i started with.

 here it is with the mocked up extensions in place.

long weekends that pay off!!!!!!!!!

   a friend of mine has this old rigid framed chopper he built back in 1979.

i have memories of watching him ride it from my childhood.

well the back bone broke.   

 he had some i-beam.

 soooo,       we built a frame jig   >;o}   !!!!!!!!!!!!!!!!!!!!!

we been needing this for a loooong time.me and all my buddies got all kindsa projects that need to be on a frame jig at some point.makes doing frame work a whole bunch nicer.       and it is universal,
i can lock any frame i can dream up down on this.   

 so we fitted a new 1 1/2 inch .120 wall dom back bone.
 in place of the original 1 1/4 x .200 or so wall thickness.
here is a crappy shot of it with backbone fitted.
unfortunately the camera died so i don't have pics of the finished tig welded out frame on the trailer heading down the road  {-_-}.................
