Thor, or should that be Zeus?

LOL you beat me to it I meant to write 35mm by the time I edited it you already posted lol, looking at the pic of your hand against them damn they're big.

If you don't mind me asking how much were the ballscrews and rails? I assume they're not cheap lol.

I need to check, I bought two sets of components from my supplier, I think all in for 4 x 1180mm 45 Bosch rails plus carts plus around 6 different ballscrews (longer length) and 2 shorter length ones plus the a short set of rails and the Rosa ones being used on my Z Axis (700mm) was around €2500 or 3000. Not cheap but the 'list' price on a Bosch 45 Rexroth with rollerbearings and a set of carts is around €1K per set.
