why there is so little interest in this topic? May be it is my english or I failed to describe the the problem…
today, having some free time, I found a way co completely eliminate movement of adjustable part of main supports. That was about 2-3 mm. My machine have 8 hex screws, and i need to adjust 4 of em, every time. Interesting, there is nothing in manual on these screws, and it is kind of strange design.
So, but, I still measure movement of central supports, because torrent and baseplate are deforming by about 3-4 mm. So my racket that is 23.85 cm without strings needs to be mounted to 24.1, to become 23.7 when mains are pulled, and finally become 23.9 with crosses pulled. I would appreciate feedback, on is it what normally happen and you observe on your machine. I think that 0 movement is only achievable on something with ring support, like merco b-200.
