hi Rogue,
Have a hunt round for a post which has a very good spreadsheet attached, (sorry can't find it or I'd post the link) you can put in info about the thickness and material of the gantry sides and see the difference it makes to the rigidity etc... and lots of other stuff to suck away the hours LOL...


(I'm rather envious of those who have already GOT something to play with! I'm still awaiting my first "delivery" :-(
