Thanks very much Jurasikfrank & Scratchy
You're right about the time i'm putting into it.....its like 3 steps forward & 4 back at the minute.....I spent a couple of nights making the docking rings again, I scrapped the last ones, they looked too big even though they were made with the measurements of the cockpit tube, so I started again....had both made, then on looking at them today they weren't circular enough, rolling the poly sheets to make them didn't work out.
Trying to plan new ones tonight.
