Rich Hale Posted August 21, 2008 Share Posted August 21, 2008 If you forge mild steel it will not harden in water....Metal things in the food chain can be coated with cooking oil Quote Link to comment Share on other sites More sharing options...
CurlyGeorge Posted August 21, 2008 Share Posted August 21, 2008 Sabre, I'll agree with Rich. Don't paint anything that will contact food. Just use cooking oil on that part. Paint only the handle and shaft, etc. I make a lot of camp cooking utensils and coat mine with cooking or mineral oil. Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted August 21, 2008 Share Posted August 21, 2008 Dropping it in water *may* make it prone to shattering. Most of the "mild steel" sold is really A36 and may have enough carbon in it to harden and turn brittle if quenched. Letting it cool in still air, called normalization, makes for a tougher steel. I toss pieces out the door into the desert, drop them on the concrete shop floor, or rest them on the soapstone slab that protects the wooden bench my gasser is on. You know the trick about sticking the piece in vinegar overnight to get rid of the scale? Washing it with water and a scrubbrush the next day and the scale washes off as a black gunk. Faster, Easier and SAFER than using a wire brush! Quote Link to comment Share on other sites More sharing options...
Sabre Posted August 21, 2008 Author Share Posted August 21, 2008 ya i guess kuz ive had my piece ripped from my hand and thrown at the wass al my hand sucked agaist the wire wheel(ouch) the rod i use is about 5/16 and is a shiny silver...i find when i wire wheel it off the shiny allmost completely comes back...i am also going to try to leave my items in the acid like the bp and ill try vinagar to... Would cromic acid work also? Quote Link to comment Share on other sites More sharing options...
metalliferous Posted August 22, 2008 Share Posted August 22, 2008 If by cromic acid you mean chromic acid, then yes it might work, but you probably shouldn't use it. Anything involving chromates is highly toxic to humans and can produce toxic fumes. In any case, it's not in kidsmith territory (or, for that matter, in most young adultsmith territory either).

ThomasPowers Posted August 22, 2008 Share Posted August 22, 2008 A cardinal rule of Hobbies is: Thou Shalt Not Make Your Home/Shop/Neighborhood A Superfund Site! Generally sticking with stuff that is easily bought used and disposed of is suggested rather than using stuff that takes special hazardous waste disposal at elevated cost! I have a 5 gallon bucket of vinegar with a resealable lid; just drop things in, (good for rusty tools too) and come back later---it generally doesn't hurt even if it's the next weekend. When it becomes weak I let it evaporate away while using the other bucket I have. Quote Link to comment Share on other sites More sharing options...
Sabre Posted August 22, 2008 Author Share Posted August 22, 2008 well i was just thinking chromic acid kuz my dad has a huge tank of it that he uses to clean off headders and engine parts (prolly spelt it wrong) ive messed with the acid b4 and it seems pretty powerfull..

ThomasPowers Posted August 22, 2008 Share Posted August 22, 2008 Will any of your items ever be used in food preperation? If so stick to things like vinegar that are "food safe" I use parafin wax as a finish for many of my "in the field forgings" as it is a food safe item and I make a lot of S-hooks, Tripods, Trivits, Toasting Forks and even a kettle or two.
