Progressing From The Dark Ages.

Hi Guys, bit the bullet and ordered a DRO for my Mill, sick of counting turns of the handles, compensating for backlash and reading the dials. The kit comes with 2 glass scales, but the "X" is too long, anyone shortened scales, is there an easy method? And yes I know Harold it takes some of the skil...
