One issue I have been dealing with is tight threads. All of
the plated screws and nuts go together very hard or will not go together at all.
Taps and dies have been purchased for all the threads I have encountered on the
bike; BSW, BSF, BSC and a number of odd ball threads such as 13/16 -20 &
9/16-20. These taps and dies have mostly been found on ebay. I have gotten into
the habit of running a tap and die into every nut and on each bolt before
putting things together. This takes off the new cad plating but leaves the
original cad film in most cases. Threads work great. I have been holding all
bolts and studs in a lathe and then hand tapping them while nuts go in a small
aluminum jawed machinist vice.
My “plan B” for parts that missed the plating process was to
paint them with a finish similar to cad. A “high temperature ceramic aluminum
header paint” was found at my local “Autozone” that fits the bill. While I
would much rather have cad this will work for now. When I send parts out for my
next restoration they will go too if the paint does not hold up.
