Sorry Andrew couldn't resist that one!
The product I'm using is a gun bluing solution from Brownells called Oxpho Blue.
My method was as follows,
1. De rust
2. Wire brush
3. De grease
4. Apply Oxpho
5. Rinse with water
6. Wire wool (fine grade)
7. Re apply Oxpho
8. Submerge part into old engine or wipe over with old engine oil depending on size etc.
The finish seems to vary between parts I guess because of the base metal. But even the worst finish looks acceptable to me.
Cheers
John

Oxpho is one of the better choices.
Hint: for a darker, more even finish, try heating the part before application. Not hot, just very warm. It helps the reaction. Also, if you apply the stuff with a rough finish cloth and really scrub it in, it works faster. Not sure if that helps, but I'm impatient.
Full of ideas, but slow to produce parts

Thanks for that, I'll give it a go next time I'm doing some parts. I'm starting rebuilding the head and there are lots of parts that need to be re blackened on that so I'll try your method and see how it compares.
Thanks

Having tinkered with a Kondia Powermill (a beefier copy of a BP) there are a few things to be cautious with the pulling the head apart.
If you pull the quill lever out the quill will drop out and end up on the floor! I always ensured it was resting on some blocks of wood before I did this.
You will also want to take the skirt off before dropping the quill, as it will shear the little ears off if you dont. The quill spring will probably come off the shaft as well and whilst it can be a PITA to get back on it shouldn't be a problem.
You will need to make a tool (if you don't have a suitable pin wrench) to retension the spring. It engages with the two screw holes in the hub and from memory it is 2.5 turns to set it correctly. It is just there to counteract the weight of the quill, not to return it to its upmost position.
Most of it is intuitive but you need to keep your eyes open for retaining grub screws that are covered over with years of grime and paint jobs by previous owners. Most of the internal parts come out in a specific sequence, so take your time and think each step through.
I made a bench stand for my head, which made it so much easier to work with. You could also use an engine stand but I found the height annoying, so made a bench stand instead.
You may already know this but I just thought I'd share my experiences.

Thanks for the info.
I haven't a clue what I'm doing so any information is much appreciated. I'm taking my time and making copious notes and taking lots of pictures. Should be fun!!!!!
Cheers

I just got an image in my mind of Darren's head on a bench stand :)

No, I was thinking YOUR head, not the Konida's!

I know! Those pics were to help counteract your imagination.
