[TheForge] Forge Welding Chainsaw Chain

[Jerry Frost]

This was a pretty extensive thread subject a while back and I did a little
experimenting.

I baked some in the oven and it ended up as a hard foam that was a pain to
crush for use. It didn't foam much but I didn't notice any difference in
performance.

I tried baking borax and boric acid with similar hard foam results. Again I
didn't notice a difference in performance.

The last experiment I tried is something I'd contemplated during an earlier
anhydrous vs. hydrous borax discussion. I welded a plate to a 2" pipe
coupler to make a little pot and melted some borax in it. When I wanted to
weld something I put the little pot in the forge to remelt the borax and
applied it with a piece of rod. Again I didn't notice a difference in
performance but the hassle factor was off the charts compared to simply
sprinkling some flux on the work.

I now use a borax, boric acid flux and don't worry about a little foaming.
If foaming does bug you simply apply it at black heat the foaming will be
almost nil and it works just fine.

If it ain't forged
it ain't real.
Wrought iron is.
