I have often thought a pair of adjustable stops would be useful on both the No.O mill and the No.1 tool and cutter grinder. Years ago I made a couple of stops for the Y axis on my other mill so it was only a matter of changing the scale to suit the Hercus'.

I had been my intention to make one pair that were interchangeable between both machines given that they share similar but not identical tee slots. A slightly oversize cross drilled hole through the "tee" bolt would accommodate the difference in the tee slot dimensions and provide the required interchangeability.

So I made a pair using 7/8" square 1214 for the "nut". They looked OK scalewise on the tool and cutter grinder but were in my mind, a bit too large for the little No.O. So I made another pair, this time from some 20mm square 1214. The 5/16" UNF threaded screws and knurled nuts are also 1214, not my favourite material due to its propensity to rust, but given Hercus used the stuff freely on most of their machines, I decided it wouldn't be out of place. Plus, it's easier to machine than 4140. The 13's adjusters are a combination of 4E cast iron and 4140.

The fixed stops had me toing and froing. I had toyed with the idea of rounding some of their surfaces but simplicity reigned. I don't think the end results look out of place. The stop on the grinder also serves as one of the three table keep plates required to prevent the table tipping off its ball bearing mount. That stop is 4E, the mill's, 1214.

The idea of interchangeabity seemed like a worthwhile pursuit but in reality it meant removing the grinder's table end covers, the table swivel fine adjuster and a pair of small travel stop screws from the tee slot. Certainly not as convenient as a pair permanently insitu adjusters.
