Alan, what's the overall length of the round bar between the feet? 900?

The spreadsheet I alluded to earlier is here; http://www.mycncuk.com/forums/showth...lculator/page3

The figures Ross mentioned in and around that post were for "25mm dia. 1500mm span and 250N (25 kg) load the best case deflection would be just over a mm but worst case is 5mm depending on the restraints."
