This is my latest mod to improve the performance of my LMS 3990 Mini Mill. I added 4-1/2 in. CRS hex rods between the reinforced table top [via 1/4X2X2 in. steel angle] & various places on the column.

The rod ends are 1/2-20 thread & have left-hand threads on one end so I can simply loosen the lock...
