I'm not sure what defines a real machinist anymore. To me it's a tool or
prototype maker who can solve problems with the jobs I bring him.

Thanks. So Bob can solidly claim the title and I barely squeak into it.

Michael Yellowhair (Praxis Precision) second generation machinist from
what I understand says the same thing to me. Not as many words.

So about AlTiN vs TiAlN...

In a local motor cycle shop I used to visit regularly (bolt on parts
store) called 3 Bros Cycles the owner would often struggle with
customers trying to determine what diameter their handle/crash/misc bars
were for bolt on crap. It drove me crazy, so one day I went through my
crap tools and found an old promotional caliper which I gave the owner.

Growing up in the family businesses (one was a hardware and auto parts)
we kept a caliper next to the catalog rack. Often we were able to match
up a part for somebody by measuring it. In the local O'Reilly Auto
Parts store they can't match up a lug bolt unless you can give the make
model, year, sub year, and sub model of the CAR, "I SAID CAR YOU IDIOT"
for your utility trailer to save their lives and you are a piece of shit
for asking. Often I look up what I need on-line and order it even
knowing they local store has a full line of the manufacturer's products
because its not worth the effort of forcing them to sell it to me. I
really would have liked to have it today, but...

When they ask the make I should just say Trail Right and see how long
they try to search for it in the computer. Its a 2001 Trail Right zero
cubic inch with the delete transmission and the straight axle.

I can't imagine going through life not knowing how to measure ANYTHING.
I actually watched a guy take a hammer to a rivet on the end of a tape
measure because it was loose. I just walked away shaking my head. I
suppose I could have jokingly asked if he was making it into an inside
or outside tape measure, but its just not funny if you have to explain it.

Yeah, I was hoping for some first person. I've read a lot online. Some
seem to claim TiAlN is better for general steel machining, but that has
not been my experience at all. AlTiN coated carbide and go hard and
fast has been my experience. They have a life, but they will continue
to cut even when its gets dull and the mill starts to glow.

I follow a few of the "hobbyist" channels on YouTube. Many of them seem
to think the smallest diamond shape inserts are the best compromise for
small lathes, and lathes with flexibility/backlash/power issues. I can
see the logic behind it. The smallest diamonds have the best chance of
getting them into the chip breaker. Many of them still aren't breaking
chips, but IMO that's a safety and cleanup issue more than a part finish
issue.

Speaking of not safe... I recall a few years ago I made "bolt action"
stainless steel pens for Christmas presents. Drilling the bodies was a
nightmare until I gave up on the factory drill edge and ground my own.
Then my best results were hard and fast deep drilling in one continues
peck with giant knives of stainless shooting out of the hole. Not the
safest to run or to cleanup around the machine but I drilled both halves
of a dozen pen bodies without resharpening the drill again.

Been thinking about making another batch. Recently somebody on Facebook
ran across one of my old posts about them and asked about buying one. I
told them what I would have to charge, and they said "if you make
another batch please let me know." Actually I have been thinking about
a combination tool. Regular Space Pen (tm) cartridge on the bottom, and
carbide scribe on the top. Just flip the pen and lock the bolt in the
other direction. I've got way to many broken 1/8 shank carbide stubs in
my recycle carbide bin. LOL.

I remember you making those and the problems you had . The tooling I
bought is 5/16" shank indexable . They use a triangular insert #TCMT
090204 . Small insert , and only uses one side . I'm thinking this
system will speed up some of the steel machining I do . Some of my
mystery metal stock has a tendency to work harden and burn the cutter if
I try to turn at too high a speed .

Some of my best projects came from stock out of the scrap/salvage

Yeah, 5/16-8mm (not enough difference (under 0.003) to make a
difference). That's what they use on the mini lathes. Might be
triangle they like instead of diamond. I just enjoy watching them do a
lot with a little.

Same here. I can keep HSS as sharp as I want and grind custom shapes, like
concave edge and screw head rounders and the angle of the grooves in a
serpentine belt pulley. Almost every job is different and one-off, so I
don't need cutters to hold size for long.

I'll still be using a lot of HSS , 5 holders are 5/16" , 2 are 1/4" ,
and the last one is dedicated for the knurling tool . I have one piece
of the 5/16" cutter stock , and lots and lots of 1/4" . The carbide
tooling is likely going to be reserved for tougher materials like alloy
steels . I've got some stuff that I can't cut with HSS , like heat
treated axle pieces . Bandsaw won't touch it , only things I can cut it
with currently is the plasma or OA torch .

Abrasive chop saw?

Mine is good for hardened stock up to about 1" wide, and might do better if
I'd paid more than $3 per disk. It also cuts thin tubing that could strip
the teeth from a bandsaw, and can notch the case hardening of scrap
hydraulic cylinder rod so I can cut it short enough to anneal in the wood
stove.

I don't have one of those ... At one time I had a pretty nice circular
saw . I mounted an abrasive blade to cut some pieces of steel and pretty
soon I had a piece of junk that would just spark and growl . I do have a
few cutoff discs for the angle grinder , so when that's the only option
I'll use it .

I've seen a better one than my Enco rapidly cut off a large number of mild
steel (?) blocks maybe 2~4" wide, in the parking lot between the company
machine shop and my lab. They are good for rebar and conduit, though they
burr the ends. Otherwise I prefer my bandsaw or a cutoff disk in a cheap,
light weight 7" angle grinder. I have good 4-1/2" and 7" angle grinders for
serious work and $15 ones that soon overheat for the brief tasks like
wire-brushing a weld or gouging out defects.

I have a pretty nice circular saw too. A nice Skil Wormdrive. It only
gets premium wood blades. At one time I was breaking down a bit of
steel to make non penetrating roof mounts for satellite dishes. The
TVRO company was paying me the same rate for the mount whether I bought
one or made one, so I made one and got paid for installing it too. I
used a Black & Decker circular saw with an abrasive blade for that, and
it lasted for years. Plastic melted and slag built up, but it kept
going. I think I paid $29.95 for that saw at K-Mart. It did finally
die, but only after many years. I got my money's worth out of it. I do
have a circular saw I sometimes use for cutting steel now, but it uses
carbide steel cutting blades. I am sure they would not hold up to
anything hard. It works great on aluminum up to a couple inches or mild
steel up to 3/8 (so far). It was NOT $29.95.

When cutting tube I always use the bigger horizontal, and set the
hydraulic down feed so it doesn't fall to fast. It works great. If I
hadn't stripped the worm gear (replaced now) on the smaller horizontal I
might have never found out how great the 7x12s are with the hydraulic
down feed control. I do have an abrasive chop saw, but it rarely gets
used anymore.

I learned on DoALL horizontal and vertical bandsaws, so I knew how a bandsaw
was supposed to work and could tinker with a 4x6 until it did so, close
enough for hobby use. I don't think it or the 30" 3-in-1 sheet metal machine
belong in a business, they need too much attention to get and keep them
right. Mine came second-hand from shops that had given up on them.
