have you tried lapping the ways on your x-y axis? i checked the gib on mine while doing the lapping and was suprised at the contact pattern on the gib strip, or lack there of. it took a while but the gib shows even wear and both axis glide smooth. i am also using tetra lube grease, it made quite a bit of difference. if you haven't tried it yet you might go that route before investing the time and money masking an existing problem. |
