Does anyone know how to get non painted parts back to that black metal look (Im sure theres a technical term :LolLolLolLol:)
I've cleaned and polished some bits up , axles, bolts etc. but want them back to looking like original
-
ive done this with a couple of bolts before, coated them in used old engine oil n hoyed them in a coal fire for a bit, it worked but i cant remember how good they looked. so that was alot of help wasnt it :LolLolLolLol:

Used to do stuff like this as an apprentice. You have to heat whatever it is up until it's bright red (damm hot) then put it in a large container of oil. You really need a large one as a small amount of oil will get very hot and possibly catch fire !
You can get chemical blacking which is used on gun barrels. I haven't used this myself but would save you having to heat stuff up a lot. There is always a risk that heating could cause things like axles etc to bend or crack.
I expect someone on here has found a good way to do it.

The trouble with heating stuff like that is you'll lose any previous heat treatments it may have had. try the kit from Frost.
