mathematics.....

working on a centre line... am now working from centre axis... all swing arms must have them or the wheels would be out of liniment...

instead of trying to just use a straight line from front sprocket to find where the rear sprocket should be...(which didn't work)

have now taken measurements from the original swing arm & sprocket carrier and found that there is only 12mm difference between the GT & bandit liniment..

so the bandit sprocket carrier has now had 12mm skimmed off it (this should work)..

Ho!!.. the swing arm is now starting to take shape.. the shock brackets are welded on.. just the rear brake caliper torsion arm lug to be welded on.. then a fitment to see that all is OK!!

if it all works.. then i could this year send off with frame & "bits and bobs" for stove-enameling and have a complete rolling frame..
