Priceless information!

I had planned to have those brackets like that for holding the ball screw suport block bearings but i suppose they could be tapered towards the middle, but i think ill be going away and having another go at all this tomororw now.

I am unsure as well on the size of the hiwin to use, type of profile and bearing block.

Planning to use 20 plate here, and bracings similar to that on the x axis gantry base.

5 mm pitch check, but what about the diameter 16 or 20?

Thanks
