has anyone thought of tapping a acme screw at the opposite side of the motor end. using a bigger bearing for strenght and cutting a hole through the bearing block , so you can put a washer and a bolt to hold it tight to the screw , thus clampping down on the bearing which is pressed between the block and the plate to eliminate backlash.[acme srcew would be milled to fit bearing.]would this be a good idea or would the bearing blow out .i hope you get the idea here. would like reply from the mighty cnc masters as im a newbee , and would like to use this idea on my cnc table. for extra measure.
