Hi Rolf,
Thanks for the suggestion. yours is a work of art and I still haven't ruled it out. it all depends on the weight of my upper and lower sections and where my pivot point ends up. it'll depend a lot on choice of materials.
I've got a hybrid design in mind, just finalizing the numbers.
the primary mirror from Orion optics is 5.6Kgs, so I have to keep weight down where possible.
with the forkmount, i'll need sliding type counterweights along two axes, have to factor that in as well.
with the string spider, have you ever noticed slack or is there sufficient tension to compensate with temperature changes?
how long did it take to build it from start to finish, and do you think there would be any benefit if the three central square tubes were spaced out a bit so the dovetail is fixed over a wider distance axially?
