hi all sorry didebt know if this Q should go in here or not but any ways.
ive just got a plate of ally its
15mm thick
1025mm long
773mm wide
its going on me cnc as the bed base i intend to fit it with 10mm bolts at both ends it will have a sheet of ply ontop as the spoil board.
my Q is i intend to have it unsupported in the middle is this a good idea? its a hefty bit of ally ive been told it holds a tolernace of 0.001" will it bend over time?.
cheers all.
