in the ultrasonic cleaner in between each
grit. Once you’ve worked up to about
2,500 grit, you’re moving into phase 2.
PHASE 2:
This is less about removing metal and
more about making the sanding marks on
the coils smaller and smaller, which will
slowly increase that mirror shine. Keep
repeating the process all the way to 7,000
grit where you do the 7,000 twice — once
with the paper dry and once with it damp.
NOTE: You should never take more than
about 30% of your surface wire off as it
will make the coil brittle.
Now you need to sort out your legs.
Do this on your core. One side is easy as
there is a nice long bit to get hold of. Just
unwrap the four extra wraps you added
that side and snip to give you your leg.
The other side is a bit tougher. Work that
end up without warping the coil until you
can get a grip on it. Again, take off those
extra wraps to form your leg.
THE FINAL CLEAN
Scrub those shiny little devils as hard
as you dare with a soft brush and some
dish soap and water. Give them a good
rinse and then pop them back into the
ultrasonic cleaner for another 10 minutes.
That’s all, folks! In the next issue,
I’ll be looking at alien coils....
