Hammer face rust pitting - how deep is too deep
Hello all.
Just picked up a Brades 1721 4oz ball peen hammer.
It has rust pitting on the face.
Can I just grind it down and smooth of the surface. Also would using a linisher belt with a metal grit be ok, or a bench grinder be better.
I am thinking of the hardened metal depth.
Thanks
Lyle.
Electrolysis for de-rusting
A year ago I had and old cast flower stand given to me, deep rust and flaking paint etc. Well for fun I thought I'd give electrolysis a go, and was staggered at the result! In an afternoon all of that deep seated rusted on rust was gone, with a dirty brown scum floating on top.
Since then I've done old horse shoes and bits of cast iron that had been buried around my 140 year old settlers cottage, and in all of them rust literally dissolved away leaving the metal untouched. Couldn't believe my eyes.
So, what did I do?
Found a plastic tub, filled it with tap water, threw in a cup of washing soda, put 3 short lengths of reo bar arranged arounf the edge that I connected to the negative terminal on my car battery charger, and the item to be de-rusted I hung into the water from a stick, with the +positive connector attached via a piece of electrical wire, and then walked away for the arvo.
Within 30 mins a bit of a brown scum rises to the top, increasing over the hours. This is the rust being carried away atom by atom, eventually creating quite a thick scum. 4 or 5 hours later, take the item out after disconnecting the charger, a wash under the tap with a dish brush, and it is back to bare metal, although blackish in colour.
This is more effective than wire brushing, and easier of course. A big item I had I did by plonking it in the tub in the morning, and flipping it at lunch time so that both halves got done. The metal is not affected by this process.
