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" :-(

Here it is:

It's a useful spreadsheet, but it wont give useful results here as you're adding the side plates mainly to counter forces parallel to the Y-axis, not X. Since the force is parallel to the plate the plate does not need to be very thick at all - 5mm would be fine, so long as it doesn't bend - so stiffen the plate if necessary.
