Hi Colin,
love the photos, thanks for posting them. What fluid are you using in your Ultra Sonic cleaner? I use tap water with a squirt of washing up liquid in mine.
Cheers, Dave.

For dirt / grime removal just tap water and a bit of dish soap (non-chlorinated). For the bright work, I replace the solution with half a teaspoon of washing soda (baked baking soda) and distilled water. I add a small bit of aluminum sheet to the cleaner so that the harder metals being cleaned have something to steal electrons from and that leaves everything nice a bright. I also use a few grades of wire brush (nylon, brass and steel) to get the extra hard stuff off.
One thing not noted here was when I reinstalled the mixing chamber core, I left it in the freezer for about half an hour to get nice and cold, then I warmed up the entire mixing body (which was bear) with a heat gun, got it nice and warm and then the two pieces slid together without any effort, once they equalized temperature, it was nice and tight and correctly aligned.

Had some more free time today so I decided to fix the clearhooters dipper / horn switch which came with my bike, Sadly, I didn't think to snap a picture of it right before, but there's probably some photo of it on one of the bike pictures, oh well
Anyways, this is what I started with, oil, rust, dirt, and broken baktelite, the outer shell wasn't too bad, and the switches themselves were in good shape
The inner core was a different story
The toggle mechanism on the dipper switch was pretty hard up with a rusty spring, and rusty linkage
So I made this
Pretty, right?
And then I applied my favorite tool, chemistry
Within minutes the rust was gone, leaving only black iron
The rust was deposited on the donor metal:
And the end result after a bit degreasing, brass brushing, and glue

whilst a small part of the overall restoration I bet it was very satisfying restoring that switch - its the little things
-thanks for posting.

Hmmm....... impressive!
What did you use as an electrolyte and what is the polarity?
I can see that one wire is connected to the parts - is the other wire just stripped off and dunked in the tank?

Hi Jim,
I use a washing soda in distilled water solution with a 12v battery supplying the speed up. The anode is a large iron nail (positive) and the parts themselves make up the the cathode (negative)
