When my Dad passed away, he had left instructions that he was to be cremated and his ashes spread on the farm he worked near his favourite spot.

Knocking chunks out is an issue with cast anvils. If you have used a mild steel for the body, any deep scars could be repaired with 7018 and ground to a close enough contour with an angle grinder.

In some respects, I agree. Anvils are intended to be used with softer steel at heat. Casual use will not give unreasonably fast wear. Any repairs could be one with less expensive electrodes.

That is the stuff. It is also not directional like expanded metal can be.

I disagree. The best non slip surface is the purpose made stair material. Similar to expanded metal, but slit with a wavy blade. The resulting serrations are on the order of 1/4" pitch and result...

As a starting point for 7018, I use 1 amp per 0.001" electrode diameter ( the wire core, not the flux ). For thick sections like your anvil, I'd add 10 - 15 amps to that.

Once I got a bead laid...

Oh so many questions..... first -what are you using for a power source? 7018 will run on DC reverse or alternating current, but is an exercise in frustration to run on AC. I find that on a home...

For exceptionally thick sections, I would consider a J bevel or a U groove. It saves removing and replacing a large volume of metal, yet still provides room for cleaning between passes and for...

I'm curious what chemical analysis is available in a maker space or home shop environment at anything like a reasonable cost.

If the material is truly a low carbon steel, I wouldn't bother with too much temperature control.

Just to make the welding easier, maybe 200-300 F preheat. 700 F maximum inter pass, and slow post...

Now I am curious. What might the welding flux they use be? Doesn't look anything like the Borax I've seen used. It also doesn't seem to spray out of the weld like borax seems to.

If you do end up machining another multi v pulley, consider using a slice of heavywall pipe for the rim rather than bending flat bar. Might save a lot of aggravation.
