Thanks Si and John, once you understand the cross sections of the plan and what some lines mean then it's easy peezy.
Firstly those round wire eyelets are not made from the plans seen here. They would eventually be turn wheels. I also made some other bits and shaft from plastic rods and tubes


Crosse frames were super glued to the round eyelets and secured to rods on the side supports. I'm guessing these wheel helped level the catapult or kept it in place once the direction was decided.


The ladder was from copper wire basically super glued..I don't know how to weld or solder properly unless I intend to do pyrotechnics like John. :smiling6:

Those bits I did earlier were for the work station...

...and for the shaft next to the high pressure turbine tube.

I straightened thin wire and made a hook at one end then threaded it through pre-drilled brace supports...again I don't know what this is for but it's in the plan.
You can clearly see the cross frame from copper sheet in this angle. The nut in the center is cut from hexagonal rod but seriously at this scale even smooth ros suffices.
I guess this sums up most of the construction...next would be threading the cables around the pulleys.
Cheers,
Richard
