    I'm considering home nickelplating for the odd nuts and bolts I want
    refurbished because hard to find. OK, buying a DIY-kit would be the main
    option, but can somebody point me in the direction of a good one? Otherwise,
    what could be the home-setup to give it a go without the kit?

    Some years ago I got the "Dynic Sales" Ni plating kit to do various
    bits for my old Panther. The process can work but it demands absolute
    attention to detail to produce a good and durable coating. I had many
    failures before realising that surface finish and cleanliness, plating
    temp and control of the pure dc current were critical. If you're going
    to try it without a kit you'll need an aquarium heater and themostat,
    accurate mercury thermometer, air suplly and bubbler; a big rheostat
    to control the current and an accurate amp-meter. Use a 12v car
    battery rather than a charger. You'll also need a choice piece of pure
    nickel for the anode (not cast nickel). Then you'll need the nickel
    plating salts (nickel ammonium sulphate) and some pH papers to help
    you control the inevitable acidity in the plating bath. The whole
    set-up needs suspending in a plastic bath of appropriate size.
    Degrease the bit to be plated by boiling in hot dish-washer powder
    solution and then don't touch it. For say a petrol tank filler cap
    it'll take at least a couple of hours of constant attention.

    If all this sounds like a massive load of buggeration - it is !

    Nevertheless, it can work and the finished pieces for the bike looked
    magnificent. There was no deterioration in them for the 10 years I had
    the bike.
    I've got the original Dynic Sales instruction sheet if you want a pdf
    copy. 'don't know what the new kits are like though.

    Using the patented Mavis Beacon "Hunt&Peck" Technique, PePe
    I'm *fairly* sure this has been discussed recently in
    uk.rec.models.engineering. You might want to have a Google, or ask the
    question over there.

    Look into the business of electrolitic degreasing too. It's the same
    set-up as for plating but you use a different fluid.

    It's a lot more thorough.

    Did I hear that Cola is a good medium for this?

    Many years ago we plated most of the small parts on the Enfield using an
    electroless nickel plating set, basically bung some powder into an enamel
    bowl of demin water and maintain 90 degrees centigrade, then hang the parts
    to be plated in the solution. It plated at the rate of a thou an hour, but
    you could only plate for one hour, then had to let the parts 'rest'

    It worked very nicely and gave a good finish that lasted well, and took a
    good polish as well.

    The only problem is I have never seen the kits since

    Cola contains phosphoric acid (that's why it rots your teeth). This is
    one of the 2 acids in proprietory rust removers. the other is usually
    hydrochloric. To get rid of oil & grease you need a strong alkali, not
    acid. Organic solvents [like trichlorethylene] will only work properly
    in an industrial degreasing bath - wiping them over the article only
    redistributes the crap when they evaporate.
    I agree about the superior degreasing via electrolytic processes, but
    dishwasher solution is a lot easier. The crystals are markedly
    alkaline and will get rid of deeply ingrained grease if boiled.
    I don't advise using one of 'her' best aluminium saucepans do it in

    I picked up 5L of Swarfega metal restorer. It has had a dramatic effect
    on the Yamaha's silencers. Certainly worth the £6 I paid for it,
    especially as it needs diluting.
