Thanks for posting that info Stewart.
I was talking to a guy today who has used the soda solution very successfully on old Lambretta scooters and swears by it. He did say though that there may be a a chance of hydrogen impregnation (causes hydrogen embrittlement - not a big deal on hinges but stressed components and the like - it might be worth checking out) but that can be fixed by baking in a hot oven so he says? He is going to send me a link to an article and when I get it I will whack it on here.
From a blasters perspective I also reckon its great as it means for a lot of moving parts such as the hinges they don't need an injection of abrasive grinding paste into there innards. The more passive electrolysis is a much better idea for that sort of thing and something every punter can do at home.
RB - I reckon you would want to check on doing chrome before you kick off and maybe do some shitty samples first. I used another electrolysis method very successfully to strip nickel of some stuff although the solution was weak sulphuric acid and the plating came off very quickly.
Another option for the chrome might be tried and true molasses and water 4 parts water to one of molasses as it only eats rust?
Just a note to you Stewie.
Spring is on it's way and that means SPRAY PAINTING TIME. Is old Jack going to look down and see some lilac hitting the metal this year?
Cheers.
