Well crud. If you are even remotely interested in reading my polemic on toolposts, you'd have to hit the "show trimmed text" or just read the quoted text here...?
Somehow trimming the 4 or 5 previous quoted messages trimmed my text too. Maybe I should stop doing this on my phone?

I haven’t used a lantern post in about 35 years. I don’t miss it. When I bought my South Be d 10L Heavy back in 1983, it came with one. I used it for several years, becoming increasingly frustrated with it. I ended up buying a Dorian BXA. Great post. You can use anything you want in it, including HSS tooling.?
I really don’t recommend carbon steel. Even finding that for lathe tooling is going to be hard to do. You can grind your own HSS or brazed carbide, or even, if you have the proper grinder, carbide inserts.

Yes, you certainly can. But, HSS has only been around a bit over a century. The modern world was built mostly without it, and with high carbon tool steel. For some things, it is still superior to either HSS or carbide tooling. Niche uses, true, but still of use. And high carbon tool steel is readily available in a much greater variety of sizes and shapes than HSS, and easier to work if you have the tools.?
Not a good choice in a production environment, it's true. :) There, fixed sizes and limited shapes work better. Fewer variables in setup & tooling. As I said before, it all depends on what you're doing.? And if one style of toolpost, and a more limited selection of tooling works well for you, which 35 years of happiness indicates, ain't nothing wrong with that!?
Some folks could get along fine with mild steel tooling. Some absolutely need carbide. I've got a chunk of Inconel here in the shop that I expect would laugh at HSS. No matter what toolpost I was using! If I ever find a use for it...
Very few wrong answers, and a lot of right answers in choosing & using a toolpost. Tooling is very dependent on what you're doing and with which material. If all you're working is brass or some plastics, mild steel would likely work well enough.?

Going a bit off topic, but I think that what you call drill rod in the US, is probably what we call silver steel in the UK. ?It is plain carbon steel, something like 1 or 1.1% C and nothing else (maybe apart from enough Mn to soak up impurities). ?Annealed, you can file or machine it to whatever shape you want, but hardened and tempered it is a cutting tool of nearly pure iron carbide for any steel softer than itself and especially for brass components, such as the profiled cones for steam engine injectors. ?You can also buy standard specs of alloy steel that can also be annealed or hardened and tempered any number of times. One little tip if you can't easily get what you need in small quantities of bar stock is to use high strength bolts. ?A grade X (imp) or 12.9 (metric) Allen screw can be filed (just) but will very readily cut softer metal if given a cutting edge. ?They are amenable to annealing. ?You might even be able to harden them further, as the strength grades for nuts & bolts are based solely on mechanical properties and not composition, so could be of any composition and heat treatment that allows those properties. ?I have made a number of small parallel reamers from them. The first railway wheel tread & flange profiles I saw being produced on an ancient lathe in Doncaster works in about 1975 were provided by a single whole profile tool. ?I later learned that the tool was not a manufactured piece but traditionally an apprentice job, to be marked and cut out by hand. ?Maybe they were allowed a milling machine for roughing out. ?They started life about 2" thick and just had the top face ground for sharpening. ?The lathe turned very slowly, but did both wheels at once, with the tools just being forced straight in. Of course, this needed both L & R hand tools. ?You tell that to the kids of today... ? Eddie

I get the messages under several email addresses. Some of them show it properly. Some don't.? Glad you could read it. And that you agree with me. :) Some folks do fine with just one toolpost. Others can make good use of more than one. There are a few that can't do anything worth a darn regardless. I was one of those for a while, myself. ;)

US drill rod is any ground rod, usually centerless ground, and is available in many types, from 1095 to O1 to S7, and A2 to M2 High Speed Steel.? Therefore specifying drill rod as a material means nothing.

Drill rod in the US to me is about straightness.

Drill rod is just a product designation: tool steel machined to very tight tolerance.
Underneath that designation you have to identify the metal itself: A2, D2,?M2, O1, W1, and probably a few more that I can't remember.?
I generally specify D2, or HSS drill rod when I need something that does not need hardening after machining, or O1, or W1 when I need to make something that will be hardened later.?
The HSS (or M2) drill rod is quite adequate for making HSS cutters or boring bars, or threading bars....

Going a bit off topic, but I think that what you call drill rod in the US, is probably what we call silver steel in the UK. ?It is plain carbon steel, something like 1 or 1.1% C and nothing else
(maybe apart from enough Mn to soak up impurities). ?Annealed, you can file or machine it to whatever shape you want, but hardened and tempered it is a cutting tool of nearly pure iron carbide for any steel softer than itself and especially for brass components,
such as the profiled cones for steam engine injectors. ?You can also buy standard specs of alloy steel that can also be annealed or hardened and tempered any number of times.
One little tip if you can't easily get what you need in small quantities of bar stock is to use high strength bolts. ?A grade X (imp) or 12.9 (metric) Allen screw can be filed (just) but will
very readily cut softer metal if given a cutting edge. ?They are amenable to annealing. ?You might even be able to harden them further, as the strength grades for nuts & bolts are based solely on mechanical properties and not composition, so could be of any
composition and heat treatment that allows those properties. ?I have made a number of small parallel reamers from them.
The first railway wheel tread & flange profiles I saw being produced on an ancient lathe in Doncaster works in about 1975 were provided by a single whole profile tool. ?I later learned that the
tool was not a manufactured piece but traditionally an apprentice job, to be marked and cut out by hand. ?Maybe they were allowed a milling machine for roughing out. ?They started life about 2" thick and just had the top face ground for sharpening. ?The lathe
turned very slowly, but did both wheels at once, with the tools just being forced straight in. Of course, this needed both L & R hand tools. ?You tell that to the kids of today...

Bill,
?? If your 'polemic' included the bit about keeping your lanterns but switching to QCTPs on your various machines, and the benefits and drawbacks of lanterns vs square posts, I saw it. I found it valuable. I lack the funds for a QCTP myself, and I think my old 10R lacks the power to drive carbide tooling, but I'm considering a switch to an Enco 3.5" turret. I can still use my 1/4" HSS in mild steel holders, but plan to step up to 1/2" HSS, at least until I get enough practice in to warrant spending the ducats on something better.

Great post Eddie . last spring we did a road trip & one of
our stops was in the town of Ely Nv . We got a unguided tour of
the railroad museum . I spent most of my time in the machine shop
just walking around & being amazed at the size & purposes?
of a lot of the machines used there . I took a lot of pics , but
unfortunately the machine that did both train wheels at the same
time pictures are just a blur . Most of the tooling looked to me
to be special ground in the shop for each machine? what ever tasks
it was needed for .
thanks

That's the one.? :)? First thing I put? QCTP on was my Atlas, since the the rocker was missing when I got it. So I made a rocker, and bought it an AXA-clone. My first lathe was a 7x10 mini-lathe from Harbor Freight. It had the tool block. I eventually got it a QCTP, as well.?
I'd been having problems with the mini-lathe, and moaned about it to my wife one day. She told me to take another class. At the time it had been about 41 years since I'd taken my first class. In that class, I learned that it wasn't the lathe that was the problem, but the operator. But I did get a bunch of experience of QCTPs on the class lathes. They had a 13", and a dozen or so 15" Clausing Colchester lathes. I mostly used the 13" lathe because it was closest to what I had at home. Not real close...?
I'd also spent a lot of time reading everything? I could lay hands on about machining. Takes practice to put it all together, but I spent over 7 years? in that class, a couple times a week. Eventually I got to the point the instructor said I was turning into a good machinist. I did some projects of my own, as well as their stuff. Had a lot of fun at it. I'd started building a small (and small machine) workshop in my back porch. That's gotten interrupted several times. Back at cleaning it up and sorting out useless junk so I can get to the machines. Not for the first time, either. Got a hydraulic press & blasting cabinet recently to help with machine repair and restoration. Once they're set up, will be working on my Heavy 10L.

BTW.? Double check my thread depths.? Initially the nut didn’t fit.? In hindsight I should have done the shaft first and then used it to test the nut threads increasing thread depth in the nut until the shaft screwed on easily.? ? If it’s done the other way around it’s really hard to realign the internal boring threading tool with the existing threads since they start from the headstock end and move to the tailstock.? Can’t see anything to line them up.? Plus holding the nut on the shaft for periodic testing is clumsy.? ? Don’t ask me how I know. John ?
