I have 1/2-10 acme screw and I am having trouble securing it
On the motor side I have it going through a 1/2 bearing block, have the antibacklash nut secure to X axis and on the other end I have the screw through a mounting flange. I dont have a 5/16 end bearing block to use so I just run the excess through the mounting flange. I have tried using to steel nuts to secure the screw but either its to tight and the screw wont turn

Any help would be appreciated, my email address is [email protected]

What are the steel nuts clamping onto? Do you have thrust bearings in your setup? For our lead screw set ups, we recommend a sandwich of thrust bearings around the main bearing block, as shown in this build log from Glacial Wanderer:
