montaldo, aren't replacement springs available from SOTA? Also, I read some years ago that the springs can be re-tempered by boiling in a pan, immersed in brake fluid. You might check those solutions, then you wouldn't need to be concerned about the arm weight.
Jelco 850 total weight
Does anyone know the total weight (not the effective mass) of the new Jelco 850s or 850L arm, as compared to the 750 total weight? I intend to replace my 750 with an 850 and want to be sure the 850 is not a lot heavier, because the old springs on my Sota table can't handle much more.
Thanks
