Frame construction/problems

I have started to put the frame together tonight,with lenghts of wood with blocks to mark the positions for easy construction on the shoot,and again built the bottom half of the 0,but its not lining up as i had hoped ,theres a bit of play in the frame.I'm hoping that when the whole 0 is together ,this will iron out these problems. The frame will be quite heavy, and Im hoping there wont be any problems dragging the number into the surf,at least it wont float.


Drawing for battery placement

Another problem is the perspex brackets ,Im afraid the 10mm perspex is not strong enough,if the brackets,or the support for the 26 power number break from a gust of wind,,they'll fall into the sea and probably be destroyed,so Im going to get some thick polycarbonate to replace these clear parts,This could be costly, I've only spent about E250 on the project so far.
