Re: [MBZ] dissimilar metal corrosion
I've had the bike sitting upside-down with amonia down the seat post since Saturday evening. Occasional taps with the hammer and this morning I put the pipe wrench on the seat post and tried some torque. I could see the frame flexing along the top bar and the seat post held firm. Next will be hot/cold treatment, I just need to locate a heat gun at work Luther KB5QHUOak Park, IL '87 300SDL (312,xxx mi) '91 Dodge Ram 150 (290,xxx mi) On 4/15/2011 6:51 AM, Mitch Haley wrote: Benz Hogs wrote: Can anyone offer suggestions for breaking a dissimilar metal bond?

Re: [MBZ] dissimilar metal corrosion
I've had a similar problem; a pipe inside a pipe. After trying all the solvents; WD-40, 50-50 acetone and light oil, Aero kroil, Blaster, Ruster Eater from Autozone, etc.; I bought an Icee from a convenience store, put a cork in one end of the inside tube, filled the inside tube up with Icee, and heated the outer tube all around with a hair dryer set on high while hitting the open end of the inside tube with a heavy plastic mallet (rubber mallet didn't work). Had to refill the inside tube with cold Icee a couple of times since it melted pretty fast. I was prepared to heat the outside tube with a propane torch if necessary but after about 20 minutes of heating the outside tube and hitting the inside tube with the plastic mallet, it finally moved a little and eventually came out.

Re: [MBZ] dissimilar metal corrosion
Ammonia diazo processing is good source - if that process has any suppliers these days. That is the old 'blueprint' developer wherein ammonia vapor turns the compound to blue after exposure. See blueprinting in the yellow pages. Take that fine schwinn to lickton's and see if they can't knock that baby out for you. Who runs the place these days? Is Bob Lickton still there? Nelson Lickton?

Re: [MBZ] dissimilar metal corrosion
Neither. It came via my brother-in-law from Pittsburgh. He looked at it and I failed to mention to check the seat post. We checked everything else. I frequent Licktons for tools and occasional parts. Bought a new bottom bracket tool from them tonight and asked about 1' derailleur cable housing, and they gave me 2 1' sections free. Good people there. I've been to Barnard's once, and they sell more BMX/cruisers than road bikes.
