Members dikman Posted January 13, 2016 Members Report Posted January 13, 2016 The doctor apparently then said that coke was the strongest food grade acid/ solvent there is. Good for the teeth to, no doubt . Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500. Chinese shoe patcher; Singer 201K (old hand crank)
Members Darren Brosowski Posted January 13, 2016 Members Report Posted January 13, 2016 Looking at those pictures all I see is oil residue not rust. yes, Uwe... I really do think it works.... My main concern was keeping the sewing machine in contact with the coke for as long as posible...hence covering it in a cloth. If I could have let it stand in a bowl of the stuff, I am sure, in the morning it would have been clean... I think coke is very cheap your side of the pond, so it is realistic filling a bucket...

Bingo, but why go the Coca-Cola route, you can get aqueous solutions and even gels (for vertical surfaces). It even gets at rust in deep pits and turns them into little parkerized areas. Coke or parkerizing or Phosphoric Acid only works on steel without nickel or chrome. Personally, I use Evapo-Rust which does a good job and can be had at Wally World and Advance Auto among others. On badly rusted things, it may take 12 hours, but hell, I got time. Art Quote For heaven's sakes pilgrim, make yourself a strop!

Art I also use evaporust. I used to use electrolysis, but the evaporust works in most cases just as good if not better, and there is no power needed, and no off-gassing concerns. Chemistry is your friend. Just a side tip, you can dissolve aluminum and not steel with lye and do the opposite with alum salts. The alum salts can eat away steel broken bolts in aluminum, and i use the lye trick to get stuck aluminum seatposts out of a steel bicycle frame. The trick is contact time. Here is a good video posted today on getting out broken bolts this way. The crucial bit is how Ave increases the contact time: He has a really funny channel. I think you may like this canuck, Art. Viewers be forwarned, he uses some minor foul language humerously. Edited January 13, 2016 by TinkerTailor Quote "If nobody shares what they know, we will eventually all know nothing."

Thanks Tinker Tailor.... That guy has a great sense of humour... My girlfriend wondered why I had a stupid grin on my face... well different from the normal one ... ...ALthough I have to listen hard to what he's saying as he has a strange accent... Is it Canadian? Anyway, I have subsribed to his channel.. .It looks fun. Alex Edited January 13, 2016 by alexitbe Quote
Members TinkerTailor Posted January 13, 2016 Members Report Posted January 13, 2016 Exagerated west coast canadian. He makes up alot of words. Silicone con-carne is silicone caulking and if glue chooched, it means it worked. He also throws in some slang quebecois french for good measure. And every video ends with a play on the saying "keep your stick on the ice" Quote "If nobody shares what they know, we will eventually all know nothing."
