Is there a thread here or intact somewhere with all the pics from Spook2's "Big Weld" threads about his forging die repair welding?

Here's one of the Hobart threads, but the pics are gone.

Those were some huge SMAW electrodes and used a lever arrangement to drop them into the work.

The very large electrodes Rufus and Tom described were used in Japanese ship building up to the 60's.
They were an iron powder class electrode fitted to a frame gravity feeding the electrode at a controlled rate on to work like deck butted edge plates.

As you most probably know IP electrodes can be made to "walk" on their own electrode flux cover and it was this characteristic the frames were utilising.

One man looked after half a dozen of the units, replacing each electrode in required. No! I have not seen of these units but was told about them from someone who saw them at work in Japan.

He went on to say the frames were banned by the Australian unions as they would put men out of work.

I always liked iron powder rods, but I guess mig killed them off.

And the vicious cycle of stores selling to every amateur the same stuff pros working under specific codes used, and therefore the demand for mostly just those few electrodes.

We used to call it "Jet Rod"--it was a treat to work with as long as the conditions were right. Long strings of nearly perfect beads with the slag curling up and popping off on its own. Of course it was only good for flat position stuff and you got the best results if your plates were prepped with generous bevels for the weld to lie in.

With good prep and the right amperage (always a little on the hot side) you could drag the rods down the groove and get welds that looked like they'd been made by a machine. You didn't really "drag" the rod, you held it at about a 60 degree angle and as the rod burned away you maintained the angle and let your hand drop as the rod got shorter--easy peasy.

In the last 25 years I probably haven't burned more than 4 or 5 dozen stick rods of any kind but as I write this I'm sorta feeling the motion as a big 3/16" x 18" long 7024 rod sizzles its way down a seam. I've seen guys making long runs hold the rod with one hand while they used the other to flip up their helmets, pull out a pack of cigarettes and light one up...
