Do u thing i nessecerly need to do a face milling of my 80x80x5mm steel tube to mount the helical rack M1.25?! If i mill it lets say 1.5mm the wall thickness will be 3.5mm which is not enough to screw the rack on the tube. I plan to weld a steel piece on the top of the tube and than face mill it and mount the rails, but i really dont know what to do with rack.The gear and the linear rail are fixed, and i can not move them and i only can play with the steel tube
