My old lead in Dayton swore by a 4 inch scale, but the digital readout on the Haas cut my scrap from 12 parts a week to 2
Kept the scale in my box for 15 years until the DRO showed me I was chasing two thousandths by eye, so does anyone still run a manual machine with a glass scale and actually hit tolerance?

A buddy of mine ran a Bridgeport with a glass scale for years, swore the numbers were all he needed, and he could hold a thou all day if the room stayed cool. Then summer hit and the shop ac died and that scale started reading whatever it felt like, his parts walked all over the place and he never saw it coming because the numbers looked fine right up until the mic said otherwise. He ended up going back to tapping with a stop and checking with a mic every couple parts, said it was slower but at least he knew when he was drifting instead of trusting a box that was lying to him. Point is a scale is only as good as the day it was set, and a manual machine will still cut straight if you know where the slop is and keep an eye on the temp.
