Shaping up nicely....i can see you'll be getting headhunted for the next Norton product with workmanship like that.
how about just using the top you have made as a dummy and just put a a plastic 5ltr can under it held onto the frame with cables ties. it will look great.
i think its cos you bring the best out in people exe.. in all seriousness, you probably have access to facilities to mold plastic. worth a thought? 20lts plastic petrol cans are available too.
Decided on paper the finm, I need to check my throttle cable clearance before attacking the aluminium After 3 iterations with paper and adjusting the depth by 1cm to clear the throttle cable route I have a pattern. (I rechecked the scale calculation and I was 1cm too deep anyway so all good) Now marked out on the Aluminium sheet ready to cut, but I have just ordered a Chicken Phal so that's probably it for toady
Front Lower section completed, in the end I had to do the angled side walls as separate pieces, I've left them a tight fit so they can be tacked and tapped in to place as we go. So I suppose I should go back to the tricky rear bit soon after a bit more pondering...
