Prussian blue just works

try to get a thin even coating on one of the two rubbing parts

prussian blue, when I finally get the link to work, broken word wrappers
ought to be shot, and survivors shot again. Unforch, its probably broken
at gmail, they've not got that right in 20 years and won't fix it. Its
not even open for discussion, BTDT. Repeatedly.
Anyway, I'll see if the local NAPA store has any Monday.
Thanks Ken.

I thought of that, but I don't know where I could src some of
that locally. Is "diechem blue" the right search term to feed
google??
Not really, Dykem is a marking out fluid rather than a contact
testing compound.
You can see what happens with just a marker pen, though. (it will
work just as well as Dykem)
If you can get it clean enough to stick, formerly greased steel is
not a good candidate. Ink with acid etch might work but I've not see
any of that since I was building titan sites around EAFB in 1960-61.
In the UK I would use "Stuarts Micrometer Blue" but I don't know
what the US version is.
But the US version of "marker pen" seems to be "Sharpie'
If you can get it truly lox clean. Or you can find one marked
"permanent" which has solvents that can penetrate the lube film.
This might be a place for candle smoke if it wasn't such a bitch to
re-assemble for testing, I usually smoke rifle actions to get a good
start on bedding them into the wood. It transfers to the wood on
contact, telling you where to carve next. Another possibility on
this side of the pond might be Birchwood-Casey's Cold blue, which
can blacken clean steel. And its un-tough enough to show the
contact pattern pretty easily. That I can get at Wallies. No clue
if they'll be open tom. though as tom. is Independence day on this
side of the pond.
