I posted a pic and question on a machinist forum, asking for ID of some small brass gages I got with some other stuff. This reply from a forum member in Wales cracked me up, spitting coffee etc. Wonderful,since on that forum, full of professional machinists, they take usually turns beating me up, name-calling etc because I'm a relative newbie machinist. "No idea what they are but they look like handy bits of brass, ready nuts ( one of the guys in work suggested "longnut" to go with the threaded bar aka long thread, he reckoned he would make a fortune (tea out of nose time) selling his cuttable metre long hexagonal nut, you just cuts it off a bit shorter than you wants, because the tape measures are Chinese inches and everybody knows thems short arsed inches (he had an inch and a half missing off the important end of his tape, wouldent change it because "it fits in my hand" We tried to explain that tapping a metre long hole, or even drilling one would be a bit of a project but he wouldent hear of it, bloody defeatist lot, they would never have put a dog on Mars thinking like that! A bit of a character to say the least."
I always love your posts....... I shall have to take your word for it that this post is "tea out of nose time" humorous.......my machinest son has gone off to work, so I can't share it with him at the moment..........
Thanks, some there suggested that the things were "gng" which is machinist lingo. All I found for that was Georgia Natural Gas, but it does have a very specific meaning among machinists. I won't give it away yet, somebody like KOT will probably know "gng."
My father is a precision machinist. Regretfully as a young woman I had a serious aversion to being endlessly dripping in oil and coolant and did not follow suit. He still runs his production shop although being close to 80 some things stump him a little longer then they used to I think. I would have thought the whole lot was scrap bar end stock but again, I did not take after my father....
Well thanks! However...I am basically a fabricator in all media, not a machinistm though I have run a lathe a time or two and solved turning problems for machinists...I'm not one. This may have to do with 'gang' work on a mill. I first thought the person had screwed up CNC but that doesn't seem so since you apparently know. It could also be some derogatory term used by them.
I recognize that! I do spend a lot of time helping my dad and often have a go and a no go control set.
Go and No Go - When manufacturing a number of parts a machinist has a certain tolerance in measurement that is acceptable. Ideal measurement is marked on the blueprint and there are 2 more numbers with + and - beside them to indicate the smallest and largest measurements acceptable. Special tools or gauges can be employed to quickly test the part on the line rather then having to do measurements with calipers or micrometers. I usually have 2 such items lying nearby when I work for my Dad. He tells me go and no go. One should go and one shouldn't if the part is with in tolerance. Sometimes it may be a threaded item, sometimes they are small pins from a special set of precisely measured pins. Just depends on what you are making. Sometimes a machine is running badly and measurements are running all over the place and every part must be checked quickly. https://en.wikipedia.org/wiki/Go/no_go_gauge
Right! Go/no-go. I've picked up a bunch of large ones made in the form of the classic dumb-bell, but the ends are cylindrical. Body is aluminum but ends may be aluminum or steel. NG end is red and G end is green. They are quite pretty but most are utterly useless to me. Which might lead the un-initiated to ask the stupid question: "Well Spring if they're useless why the H did y'all buy 'em?" Well, genius, because I could!
