Parkerizing my parts on the 1960 FLHF build

[Saddletramp]

So, I have been Parkerizing many parts on my build. Some have turned out very dark and some have turned out a charcoal gray .The process is somewhat labor intensive, but the results are so cool. I'll post pics if anyone is interested.

I'd be interested in seeing your parkerizing labor intensive pictures James.

Generally, this signifies different carbon content in the steels.

a lot of hardware was 1040, it goes charcoal.

treat sat 4140 the same way and it will come out more grey,

this assumes everything is otherwise the same about your prep, bath, and after bath oiling.

a trick is to give those grey bits a good surface roughing with 120 grit oxide in the blast cabinet and reparkerize. I found that usually gave me enough surface area to get enough reaction going to make the parts more uniform.

done right, parkerizing holds up for decades with almost no fuss. See a brown spot, rub a little oil in and you’re golden.
