120 or 125? How many marks between 120 and 0? Picture?Curious, are the 0-120 dials metric or something?
Will double check tomorrow but after looking at one on the ebay, like you say, it is probably 0-125. So each hash mark would still be .001 with that 8 tpi screw then? Why was that done, seems confusing...120 or 125? How many marks between 120 and 0? Picture?
125 would be 8-tpi lead-screw.
Yes, still .001. I believe early machines had 8-tpi cross-feed lead-screws, back when it was common to think and design in fractions.Will double check tomorrow but after looking at one on the ebay, like you say, it is probably 0-125.
