    I was a bit surprised to see it, too. Been so long ago I had to open it to see what it was about.

    If you really want that saw top shiny, the first step after having any oxides reduced electrolytically, should be buffing with a a cotton buffing wheel & polishing rouge. When you are done with that you should be able to see your reflection in the top. Then put on a protective layer of a microcrystalline paraffin based wax.
    But as long as you were getting it electrolytically cleaned, I would have checked into how much it would have cost to have it nickel plated as well
    Didn't have it done. Electroysis is a simple process to do at home.

      I'd like to learn more about electrolysis, I've got a lot of rusty stuff from the house fire, is there a place to get plans for a home unit?

      Thanks

        It's pretty easy. I did it on a a couple old Number 7's, and an 8 planes this summer. I first saw the idea in this thread: http://www.bt3central.com/showthread.php?t=47853

        A google search on electrolysis will give you a bunch of links. I ended up using a couple lengths of rebar, a large plastic storage container, and my battery charger. I used some sodium carbonate I got at HD in the pool supplies.

          Guys, not to hijack the thread, but has anyone ever used a cold gun blueing process on their tool tops?

          I have a newer Powermatic table saw and a pretty old Parks band saw that I'd like to keep in nice condition with minimal effort.

          This would permenently render the iron rustproof, and be not nearly as tempermental to moisture. It would make the tops almost black, but so what?

          Just bouncing teh question off you fellers. Heck, I don't even know if it would work on an iron top. I know what it does to steel, and have had very good luck with it.

            From what I understand, bluing is not very rugged. If your tools are going to sit over in the corner & mostly just looked at, you might consider bluing. But you can expect it to be worn off quickly if the they are used often.

            Here's a link: http://en.wikipedia.org/wiki/Bluing_%28steel%29

              Click on the webshots link in my signature line. The plane rehab album explains the process.

                Few more questions for the experienced:

                What solution of sodium carbonate (x cups per gal, teaspns)

                I would think it is an outside job due to the hydrogen/oxygen

                Thanks

                  The gas emmission is minimal. I do smaller parts in a plastic tub inside. Larger parts I are done outside simply to make it easier to empty and clean up the tank. The used water looks nasty but is safe to the environment.

                  Using straight sodium carbonate I mixed about 1/4 cup in a 15 gal tank. If you arfe using Arm & Hammer Washing Soda you would need more.

                    Stopped by HD at lunch, no Na carbonate, only pond supplies. Lowes web site shows AquaChem shock treatment, is that it? Do you have a brand name?
                    I'd like to get this going this weekend and I live 30 miles from town.

                    Thanks
