Hi Mark,
Your work is looking good
Just an observation ??? it looks as if the bracket that holds the tank anti roll rubbers has been cut short???
there are normally two sets of holes for the rubber to accomodate different tanks
Those rubbers are vital for stable tank mounting
Sometimes theres not enough room for the pipe insulation on top of the frame causing the tank to sit too high or at a silly angle, its amazing how many badly fitted tanks you see !!!!
I have used 1/8th gasket rubber on some frames as this is all there was room for
The tank strap is intended to bolt the two sides of the tank rigidly together, make sure the strap does not foul the anti roll bracket, (maybe thats why yours is cut short???)
Sometimes a step or notch needs to be cut out from the middle of the strap
Regards
John
