I feel like it would need a double pole switch for safety. At least by todays standardsThe Mill/Drill I had in the 90’s was wired that way: just got a 220V bulb - cheap, easy and most importantly SAFE.

To meet Code, yes; however, if no changes are made to the machine or lamp not necessary to meet code. As long as the frames are grounded it’s safe (don’t change the bulb without pulling the plug!).I feel like it would need a double pole switch for safety. At least by todays standards
A two wire lamp would not be grounded though. Unless yours was 3 wire. I don’t think you’re supposed to rely on a indirect ground.To meet Code, yes; however, if no changes are made to the machine or lamp not necessary to meet code.

I can talk to this, 'cause I tried it with my knee mill. Then one day with the light on, I wanted to turn the X crank faster, so I balanced myself with a hand on the lathe (which is grounded).As wired the lathe is grounded just no neutral. And make sure nobody takes this as combative. I’m just looking for why it’s unsafe.
This is the reason to change the machine now. You don’t know who will have it next and what their understanding will be. If it gets wired correctly when you have it you can have some confidence that it won’t become a hazard in the future.I can talk to this, 'cause I tried it with my knee mill.

I let go REAL fast, and I'm just happy that I was able to. The ground wire should have been capable off carrying away all the current that the hot wire brought in, but when I touched the lathe I created a parallel path for the current to flow in. And some of that current took advantage of it. The only reason I was able to pull back is that the ground did take MOST (not all) of the current.
You'll notice that the neutral wire in all your other circuits is covered, and protected just like it is a hot wire. Well, that's because IT IS!! That neutral wire has to carry just as much current as the hot one.
I think "but how" is a valid question and I think it's a shame how often it gets shut down. I was worried how he started off sounding like "I already plan to do this the dangerous way, but...", but I have been encouraged by the level of discussion that's happened here in spite of that."But how"
Unless I misunderstood, he already committed to implementing the proper solution a while back and all the dialog you're referring to was in the first few replies. Everything after was supplemental."But I don't want to buy another wire and a plug."
"Buy the wire and the plug."
IMO if it's worth doing then it's worth explaining.
You provided enough insight into your own thought processes for me to understand that if you were the one with unanswered questions on this topic, there would probably not be a forum thread about it.Meh.
I know it's a bad idea to weld on zinc plated material without proper ventilation or a proper respirator, because I was told it could make me very sick or even kill me. I don't need to understand the chemistry or how it affects human anatomy or have any of those details explained to me. "It creates gases that could kill you" was all I needed to know. Especially when the same information is given to me by multiple people.
I suppose if I was a "doubting thomas" and really wanted to know, I'd do the research on my own from qualified sources. As many smart people that are on this forum, in matters of things that could kill me, I'm going to find sources that are known to be accredited - some of the people here are, I just don't know that.
I will (almost) always err on the side of caution and NOT do the thing that is against protocols and that many people have told me "it can kill you" - even if I doubt their claim.
