1982 Shimano 4000 build.
Avro:
...so on to the anodising itself. The new tank's aeration works a treat although I had to add a series of lead rings to the tubes so they stayed put. Here are the cranks, in their jig, in the anodising tank with the aeration system in place:

Switch it all on and wait!

I am using amperages and times from previous work. It is handy having a number of previous successes to draw on in this regard. The parts do not look a lot different coming out of the tank, they just have a dull lustre to them. Anyway on to the dying phase. I mix up my dyes with tap water as I live in a very soft water area. At this stage you don't really know how good the results will be, it could completely fail meaning you have to start all over again "nono"
The cranks were dunked in the dye for around 20 minutes, this is what I fished out:

Not looking too bad. A quick rinse in cold water and then dunked in near boiling water for another 20 minutes and hey presto blue cranks. I am really pleased although the chainwheel is a bit too dark, I had to do the chainwheel twice already so it will have to do. The Shimano 4000 is nearly done.

MrD:
Avro, you my man have made my day. That Sir is a brilliant video with enough detail to keep me watching. nothing better than putting spare time to a creative use. I'd love to know what polishing/sanding tools you use or is it totally by hand? Ive experimented with the dremmel sanding tubes/cylinders but maybe I need a linisher?
Again great work - I also know how long those video's take to put together ;)
Cheers
MrD
