Aloris was going to charge me 120 labor to replace the sliding gib, decided to do it myself. I thought it would be straight forward, and it was. Except, the gibs needed to be fitted, and I did it the hard way, filed both of them to fit the tool post and filed some more so the tool holders will fit freely. It was well worth it. The tool post handle when locking any tool holder, it is right at 90 degrees to the bedways, 6 o'clock with the old gubs. With the new fitted ones, now the handle fully locked on a tool holder is somewhere about 4 o'clock
