J.L.S Posted September 10, 2019 Share Posted September 10, 2019 Hoi, In a while ill get back to the forge to work on some forge welded tools, for that id like to test a mix of borax with steel filings. problem is, my collection of steel filings is contaminated by oily drill chips, so questions: does that matter? best way to remove oil from steel filings/dust?

ThomasPowers Posted September 10, 2019 Share Posted September 10, 2019 Oil will burn off way before forge welding temps. It may scavenge some O2 while doing so. Link to comment Share on other sites More sharing options...
Frosty Posted September 10, 2019 Share Posted September 10, 2019 Nope, oil isn't a contaminant so long as it isn't toxic. Occasionally I use a little 3 in 1 to make the flux stick while I close the weld up. Frosty The Lucky. Link to comment Share on other sites More sharing options...
