I think I will paint it mate.
I have finished the weight component and it all works now. The scope balances perfectly with the ED80 on top now.
The weight is a sealed section of RHS filled with lead shot so I can add or subtract weight if needed. Once sanded smooth and painted it should also LOOK attractive too.
I will be adding the instructions to the A.S.I.G.N. DIY page soon.
