Hi Shoppy people,
I've got a BT48 alpha with 8' powerstick. I built the table surface from 30mm laminated end grain balsa with vacuumed E-Glass . It's stiff and stable.
However! The table floats resting on the support rollers ie. there is no downwards vertical support out at the table edges. If the weather changes or the Gods sneeze I can get a little upwards flex in the table and it stuffs up my Z axis accuracy (not much but enough to be annoying).
I thought that adding another set of V rollers at the sides, or even spring loaded presser rollers on top would help.
Before I re-invent the wheel, I was wondering if anyone had come up with a solution to this problem?
Thanks, Steve
