Hi Guys and Gals - I looked at the bearings and there's a large cost up if I go to 30 or 35mm rails. 25mm seems to be reasonable even less then 20mm in some cases. So 25mm it is.... I was hoping to find a stack height match but that's out as well. I could look at the 12mm screws and bearings but that sounds a bit small.
Have to do some numbers on buckling and vibration.... seems were rebalancing the design Peter
20x900mm $177 set 25x900mm $172 set 30x900 $360 set I've just placed my first order with BST for my router build will be interesting in timing to get here. Xmas is looming and various things slow down about now...
