Yeah, not really. I was just bending some rod using a rosebud to heat
up the bend points to make a new handle for my roll around compressor.

I was always paranoid to just grab the rod with my hand and bend it, but
after watching a gazillion and three blacksmith videos during my morning
coffee over the years I decided to give it a try. I think point heating
the bend points with a rosebud puts less heat down the rod than welding
does.

Clamp the rod in the vise. Make the bend point glow red (little past
dull red) grab the end and bend. After several bends it started to get
a little hot where I was grabbing, but that's what the wash sink outside
is for.

I know. I know. You all knew this already.

One thing that would make this go faster is to make a hanger for the
torch, so I can just set it aside and leave it burning when I need both
hands to move something around, or hold the part while I loosen and
tighten the vise. Still it was pretty fast.

Now I need to do it all over again with a piece of stock that is
actually the right size.

--------------------------------------------
In the class I straightened part of a yellow-hot truck coil spring by
hand, with the hot end in the anvil's hardy (square) hole. The effort
was wasted when cracks appeared, but it showed how weak hot steel
becomes. Instead I forged the blade from an old leaf spring from home.
His anvils were mostly mounted on bases of angle iron.

Pipe over the rod will help you bend a tighter corner.

3/16" steel TIG/gas welding rod is great for quickly bending up custom
tools like the torch support. It's fairly easy to bend with a vise or
anvil, stiff enough for long fireplace rakes and pokers and hard enough
for single-use punches when a nail would bend.

I also use 5/32" stainless rod to make parts for outdoors, like
removable hinge pins. I bought some of all available sizes in steel, stainless, brass and aluminum, those have been the most useful.

Supporting clamps and hangers etc are available for pipe and conduit but
not fractional-sized rod. I think floor flanges and these are the most
useful for assembling temporary supports: https://www.lowes.com/pd/AMERICAN-VALVE-1-in-to-1-in-dia-Galvanized- Split-Ring-Hanger/3223515?

My 36 Lb (0-1-8) anvil may have been meant for tinsmithing and other
lighter tasks, it's plenty heavy enough to flatten and shape sheet metal
and removes the temptation to hammer on the mill table, or lathe
tailstock spindle as students did to mine. It's a London pattern forged wrought iron antique, apparently an English Wilkinson though a step in
the uneven surface stopped the lettering at Wilkin. My leg vise is also relatively light for hot forging, they make a good pair.

A leg vise is a nice tool, but it takes up a lot of dedicated
irretrievable space if properly installed on a heavy post set in the
ground. However if done that way its amazing for heavy work.

I tend to use the 4 inch wide Columbia vise that is bolted to a heavy
steel work bench. I can move the bench, but its close to my max ability
to move something not on wheels. That bench and vise will likely be
going outside under the new shade structure when it arrives. I might
even bolt the bench down since that will also be near my blacksmithing
area.

For bending rod a piece of pipe is "okayish," but pipe is relatively
soft. I've made square u-bolts out of 1/2 inch room temperature 4140QT
with a nice bend using a tool a friend gave me. When he gave it to me
it wasn't a tool. It was just a piece of 1-1/4 or 1-1/2 round bar about
4 feet long. I bored a 1/2 inch hole in one end, and it became a u-bolt bending machine. Unfortunately that piece of bar has made itself useful
for many other projects and I think I only have a few inches of it left.
I know where there are some old axles I could scrounge... NEW TOOLS.

To be fair I do use a piece of pipe as a cheater bar on my 6 ton arbor
press. I really should just make a longer handle for it, or better yet,
bolt it to a heavy bench that is actually bolted to the floor.

I meant to slip it over the red hot end sticking up from the vise to
tighten the corner of the bend, and protect your hands.

Today's flea market treasure is a lightly used Ridgid 65-RA 1" to 2" adjustable pipe threading die. https://www.zoro.com/ridgid-manual-pipe-threaders-1-in-to-2-in-rod-no- rod-bolt-no-bolt-36565/i/G2941495/?

Reviews suggest it can be misused, it may be the type of tool the
foreman shows you how to operate. The manual on line is for the later TC version with a goof-proof pipe centering clamp. Does anyone have
experience using them, or sharpening the dies?

That's an expensive bit of kit.

I don't have to thread a lot of pipe these days. I have a couple Harbor Freight sets for "heavy" threading, and some Chinese round dies that I
had to make die handles for because every one was a different size.

Back when I worked in my dad's hardware store we had Rigid dies and
ratcheting die holder, and a power drive with a large 3 jaw chuck. I
spent whole afternoons standing out in the sun threading pipe to fill
special orders.

I also broke almost every stock piece of glass in the store once trying
to cut a piece of glass for a customer window repair. LOL. The
customer was standing over me the whole time. I finally told him to go
next door to the grocery store and get a soda or something. All of a
sudden the glass snapped just like it was supposed to. By the time he
got back I had reframed the panel and had it setting out front.

Over $1000 new, much less on eBay, comments complain that they are heavy
and awkward. This one was from an estate IIRC and he asked and got $10.
It's an old model, closer examination showed no chips or oil to indicate
that it's ever been used.

Instead of tapered cutters it moves straight ones outward with cams as
the thread progresses, since it clamps to the pipe and has a positive
screw feed. There are suggestions it can cut NPS straight threads
somehow, and adjust the depth of cut.

Apparently if you purposely misadjust the pipe clamp stops it can cut a drooping or slightly angled thread to ensure positive drainage in the
pipe. The newer model eliminates that option/mistake.

I use 2" pipe for hoists and inch and above for mechanical structures
like a swiveling and rising solar panel mount. 1" pipe is the largest
that fits in my lathe spindle bore.

It was an interesting visit. I chatted with a woman promoting her self-
help book and a man selling his tool invention. Neither was close to a profit, which reinforced my decision not to make and peddle my ideas. I mentioned my sink spray for the shower online and later saw a version in
Home Depot, but it didn't sell. Apparently the constant droning about
climate change is all talk and no action.

Almost the only 3D printed items I see for sale are fantasy figures,
very rarely something useful. The practical items are still wood or
ceramic, fabric or leather. I haven't seen anything from a home machine
shop.

Usually home or small machine shops get into a specialty area related to
a hobby or special interest. Like I make fishing lure molds (primarily)
and a few other things. One fellow I know makes air gun parts. More
than a few airgun makers are or started as home shops. I believe Wicked
Air Rifles started that way. One fellow I know makes aluminum AR15
pistol grips and heavy aluminum sonar brackets as a side business (but
he runs a full on production shop). There are a number of RC hobbyists
making parts at home. One very talented surgeon I know designs and
machines prototype orthopedic devices in a spare bedroom in his house
not to far from here. Most start out doing it on the side, build some reputation in their interest community and they grow. I know of one guy
who has a steady side business 3D printing plastic shims for glad hands.
Lot of people use 3D printing to supplement some other production or
semi production process like metal casting.

Generally though it has to be something you are passionate enough about
to work at like a real job.

My son's 3D hobby got him in with a buddy of mine and got him a teaching assistant job at the local community college, and I am sure that had
some impact on his job running the machine shop and the hydrodynamics
lab at the associated university. Okay to be fair he mostly prints
fantasy figures. LOL. We have done some experiments testing 3D models downloaded from the internet before spending expensive metal and machine
time on them, and we have made master print molds to be able to cast
silicone molds for resin casting more practical items.

There are a lot more people than you think making stuff in their home
shop as a real going concern. I am not a unicorn.

The Internet is absolutely what makes many small maker businesses
possible. Without it, I'd probably never have gotten into mold making,
and even if I had I'd be relegated to advertising in the classifieds in
the back of trade and hobby magazines.

I do trade world wide because of the Internet. I have customers from
Australia and New Zealand, across both Americas, the Caribbean, and
several countries in Europe. I just shipped some molds to Germany, and
just received a custom order from Port of Spain, Trinidad and Tobago.

Without the Internet I would struggle to even sell across the USA. Word
of mouth wouldn't help much either when probably 9 out of 10 of my
customers want to keep their mold connection secret. With the Internet
the word of mouth I do get is amplified across on YoutTube, Facebook,
and Instagram. Every time a customer says he got his mold from me on
one of those platforms a bunch of people see it.

Of course the unhappy Karen's of the industry also get their bad word of
mouth amplified, but its just part of being in business. I've been in
business my whole life.
