7018 SMAW 3.2mm dia (1/8th-inch dia.)
Had to do it.
Overwelded anyway.
Started with a bit of v-up just to be sure.
But light frame angle-iron to a heavy steel column. Undercut on light
section difficult to avoid.
Time-served guy showed me.
I didn't want slag running-ahead. Seemed wrong to allow that.
Had nicely formed "finernail" of weld pool showing. All looked good.
So, nice medium burn of rod (Amps), slight downward slope, ran
downwards slow enough to puddle, but fast enough to leave all slag
behind.
It did look so right.

Comments about doing this? Good tips?

Thanks, I have a lot of trouble joining different thicknesses. Does "slight
downward slope" mean the rod or could you reposition the column?

I have enough hoisting gear to usually reposition the small-scale welding I
do. My trailer and the rusted fenders of my truck bed were much easier to
patch upside-down.

The 16' long overhead gantry track has been a very useful addition to my
kit. So far I've used it only with center support although it was tested
without it. I attach wheels on one end and a trailer coupler on the other to
tow the beam to the work site, and added pipe clamp bases to boat trailer
winches to raise it to the tops of the supporting tripods.

"Slight downward slope" is the welding rod.
Your hand / the end of the electrode is higher than the tip of the
electrode.
Downward slope to tip is something like 10deg.
Keeping narrowly / accurately it at whatever is found best is
important. You mustn't move the rod by rotating your wrist - you must
move your entire hand to keep that slope.

I have seen so many "not welds" when done vertical-down with GMAW.
Conversely, even as the agency temp, the foreperson has said "Rich - I
want you to go do that weld vertical up" (knowing I will set the
machine, do it vertical-up, etc.)

So the idea of doing a vertical-down weld with SMAW 7018 didn't come
easily.
The weld is non-critical - stresses would be very very low -
especially as very over-welded.
But my impression was - there was nothing wrong with the weld -
fluidity looked good.

I practiced welding up and down with industrial machines in night school,
and the disappointing results convinced me to buy a lift like this as a
welding positioner so I could weld everything horizontally:
https://handtrucks2go.com/Foot-Operated-Hydraulic-Platform-Stacker-Curved-Top.html

I paid $10 at the auction and $40 to have the hydraulics rebuilt so it would
work again, though a lever chain hoist can substitute, doesn't droop, and is
reachable from all sides for fine adjustments. The upright frame is very
convenient to clamp to. It's also useful to load heavy stuff on or off the
truck, support long stock on the horizontal bandsaw and fix outdoor power
equipment at a comfortable height, the carb at eye level for instance. When
idle it's an extra shelf.

I can reach a fair level of welding proficiency with practice but I don't
need to weld often enough to maintain it. My main problem-solving machines
are the lathe and vertical mill.

It's so much easier and quicker to weld in the flat or the
horizontal-vertical (for fillets) - the 2F/PB.

There are welding positioners with axis rotations and a rotating
turntable to huge sizes for always presenting welds in a favourable
orientation.

-------------------

I was looking for an inexpensive and compact lift suited to a larger
hobbyist sized welding project, a plane, car or trailer frame for example,
and with multiple other uses to justify its cost and space. I think an
unpowered "stacker" fork lift would also do. The advantages over a hydraulic
scissors lift table are greater height and the clear space underneath, to
hang a trailer frame vertically, the disadvantage is the upright frame that
makes lifting a riding mower difficult. It does hold my snow blower well.

Although I paid to have the broken hydraulics rebuilt I later found that a
1/2 ton lever chain hoist was a good substitute for it, one that doesn't
leak down like a worn cylinder and can be adjusted from the front or side to
nudge a right angle joint clamped to the upright and platform into exact
position.

I used mine to cut and weld the 2-story-high steel columns for a friend's
house restoration project. After buying the old house he found it had been
built to third-world standards by foreign labor, which is not just a Florida
problem. The steel supplier had engineered the structure and cut the top
beam to length but the columns needed individual custom fitting, and bolting
plates welded on the ends.

He told me a woman had delivered the steel and helped him muscle the 600 Lb
beam off the truck. I only had to hoist it into position with my 2 ton chain
fall. They erected temporary stud walls on either side to support the
weight.

Thanks. Your own accomplishments are very impressive:

I recently looked up rope splicing. The suggestion was 4 tucks for manila, 5
for nylon and 7 for mooring lines. I used 7 for my nylon log handling
slings. Using rope loops hung from pulleys allows rotating the log to
inspect and debark it, and position it on the sawmill for best yield.

I wish that didn't make the current in-employment demography run
scared from me, here in Britain.
"Post-industrial" seems to have come with a reliance on a money-spring
which bubbles out of the ground and spreads across the economy at
constant invariant rate. Creating new value-system in which I am left
looking like some "Don Quixote" figure.

An impression - fair or not?
So many "entrepreneurs" driving around "the Queen's highway" in their
German limosines are solely funded by from-the-State money, in a world
which is competitive but only between each other.

I just had a good 7-day assignment as a welder on the running repairs
of a ship berthed at a nearby port.

Splicing is great.
Splices are very strong and tough.
However, they take longer to make so tend to be used in something
which is permanent or has long-term use. Like a strop (you join the
rope back to itself, to produce a ring of rope).

I use a lot of tucks because polymer rope is slippery.
On a 12mm rope, I tend to make a short splice at least 200mm long
(1/2" rope - splice 8" long). Tend to do slightly longer still, then
if you use it to carry something over your shoulder, have the bigger
diameter short-splice region on your shoulder so {force over a bigger
area} is less pressure and more comfortable :-)
Can carry a lot onto a construction site that way, balanced
left-and-right with things on strops both sides :-)

You can easily make a
fid
with tinsnips from an offcut of sheet metal.
Easily produce a neat splice and doesn't introduce any bad habits or
anything like that.

Heat-seal the end of each of the 3 strands so as splicing, the strands
stay tight together as spun.

Your one about can rotate on pulleys - means wear on the rope is not
concentrating on one place. = good.

On construction sites, for most applications one would advocate
3-strand cut-film polypropylene rope ("disposable rope") because

* compensate for lower, but still very high, strength with larger
diameter makes rope easily to handle / hold

* the rope is so cheap that you can freely replace it as it
accumulates wear-and-tear

The latter is the big advantage in every way.
You don't have to plead to anyone else to be able to replace 3-strand
cut-film pp. rope...

Attila the Hun was a hero among his vassals because he confiscated and
redistributed the wealth they envied but weren't capable of creating
themselves. That's still the goal of the Left. They claim to help the People
but the people who benefit most are their politicians and greatly expanded
bureaucrazy, their dependent vassals.

Because of Attila and his kind, a thousand years of dystopian Dark Age
displaced a thousand years of rising civilization. London didn't have public
water and sewer utilities like ancient Rome's until 1852.

Soon there was nothing left to steal and no incentive to create more.
Anarchy enabled banditry which halted trade, each community had to become
self-sufficient. The answer was feudalism, submitting to the local warlord's
protection.

A similar collapse occurred in Russia after the Revolution, until Lenin
reintroduced private enterprise with the New Economic Plan. Then he died
suddenly, Stalin couldn't make it work, and ruled like Ivan the Terrible
instead. China has learned from that failure.

Although he is remembered as Rome's enemy Attila was actually a friend and
ally of the last great Roman leader, Flavius Aetius.

-----------------------

A fid was maybe my earliest metal project as a kid. It came out well enough
that I still use it.

The second was sheet metal and nail bearings for a windmill to tumble stones
and scare the birds from the garden.

The next was a pair of ratchet wheels for a model catapult, cut from
aluminum on a table saw. The ratchet claw and other metalwork were filed
from brass. Otherwise I made everything from a large pile of remodeling
scrap wood, including shafts, pulleys and lantern-wheel gears.

The Latin teacher was quite impressed with my model catapult (onager) and
similar cord-powered crossbow, until she found out how powerful and accurate
they were. The 'lost' secret appears to be cotton for the torsion winding. I
had to use only the smallest firecrackers without taped-on gravel as a
handicap in battles across the street because they could be placed and timed
for an air burst so closely.

At school I made and sold silent, low-profile pocket catapults we used to
instigate food fights between distant tables in the cafeteria, without
raising our arms suspiciously. Coming down the stairs, at ceiling height you
could faintly make out bits of dried whipped cream protruding below the
white textured ceiling in a large circle around our table, heavier jello and
peas flew lower. Otherwise we left no trace and our table with the class
officers was above reproach.
