    I have just zinc plated lots of parts with teh Eastwood zinc plating kit. $69.00 & free shipping.

    Very simple & actually fun to do. You'll be looking for things to plate (seriously!!).

    Have fun!

    Cool, I wonder if it would stand up to a buffer instead of hand polishing? Do they say how many sq. in. it plates for $70.

    But what parts on our Commandos would be good candidates for this?

    Pretty much all the nuts and bolts, as well as any other parts that were cad plated when new. I've used the Eastwood tin-zinc kit to plate a lot of nuts and bolts, as well as some other odds and ends, and the final result looks very much like bright cad. I don't think it is as good as cad for long term corrosion resistance, but it's pretty good, and the price is right. I've also used their copper plating kit, and it's just as simple to use.

    I used the Eastwood system a couple of years ago. No big problems but the system is really not sized to plate the hardware for an entire motorcycle restoration. Last year I purchased a CopyCad system from CASWELL


    Not only are their chemicals and anodes of high quality, they oversee a plating forum where there are many plating professionals and restorers who answer your questions. Their instruction manual is more like a textbook with a wealth of information.

    Based on my experience I would also get their clear chromate solution to preserve the bright zinc plating. Also purchase a good regulated power supply (3 amperes minimum). It is key to calculate the surface area and adjust the current accordingly (0.14 amperes/ square inch). Ebay has many options for power supply, it is hard to regulate the current from a battery.

    I have found the Eastwood kit to be great for small parts. That's really what it is intended for. It will quickly pay for itself.

    Whether the finish will stand buffing on a wheel depends on the time in solution (read: thickness). But, the dull zinc finish will clean to a shine with fine steel wool. I found the rubbing paste to be a bit labour intensive, but compound can bring the finish to a bright shine.

    For example, I plated a set of Yamaha spokes I could not have replaced, heads of rare Yamaha panhead screws: various small sheet metal parts; axle spacers; dust shields; coil brackets. Basically, anything that was zinc or cad plated.
