here is my first step for a permanent setup
i think it looks nice and even looks like a rocket!
150mm outside and 10mm wall thickness, part of a cranes hydrolics i believe
300mm by 12mm base plate, 2 times 200mm by 10mm top plates, 1.2m tall and 12mm plate gussets
i think i will be buying the MAL G11 to meade adapter and bolt that to the top plate
next step the concrete plug
