So would this be suitable?
Yellow = Thrust bearings
Red = Bearing blocks with radial bearings
Green = Lead screw

for ballscrew end bearings you should be looking for cheap chinese
ballscrew endbearings in the FF and FK type, and have your ballscrew or leadscrew machined to suit.
I like your side panel members, they are similar to mine. You should think about doing the same thing on the Y axis ends, but do them in aluminium, maybe about the 16 to 20mm that the others were saying.
it is the ballscrew end bearings that got me too.
i also got my bearings from linearmotionbearings2008.
don't define your machine around the parts you find of their site, ask for an email address and go through a quoting proccess to get exactly what you want.
his ballscrews are nice and cheap, don't rule them out just yet, he will get them machined at a really small fee.
however last time i asked he would not supply those FF and FK end bearings you'll have to find another supplier.
Thanks for the suggestions mate.
I am trying to make this as cheap as possible so that rules out the ballscrews as one support costs as much as my total order of trapezoidal (acme) screws.
I will most likely build another machine and that machine will incorporate ballscrews.
Thanks
