New build help needed

[Rufe0]

Any particular reason your using so many cross members? Just out of interest how far are they separated? Its certainly not a bad thing, the more the merrier I would think, however I think it would be significantly stronger in terms of deflection to have fewer cross members that where triangulated to the bottom rails rather than more with no triangulation. Having more would be beneficial though because it would support the sheet more evenly along its length.

They are 311mm apart when the base is 2800 x 1650.I was thinking of having the lower grid of the base free for storing ply .
