Some time ago a clever user designed/constructed an add on variable length clamped 'lever' or prop at the back of the dish to minutely alter the dish elevation.
It consisted of two lengths of round metal rods with screw threading on one of their ends which screwed into the end of a 'piece of metal' with a gap in the middle so as you turned this 'joiner' it altered the length of the rods +/- and thus pushed up or pulled down the elevation of the dish minutely and rigidly.
My 1 m dish has developed a bit of slack in its elevation and needs now to be 'propped up' with a 'bracket.'
Being able to adjust this prop's length slowly with a screw system by hand would allow extremely accurate elevation.
Any ideas, please?
