hot blue part deux
Sunday started with a blast, literally…
(yeah I know, I need a haircut and loose some weight...)
Before blasting, while drinking my coffee I had already removed the previous bluing with "naval jelly" and washed the piece with "simple green". I dried everything with an old hair drier that I have.
To fix the problem with the bluing salts I took and easy approach. An over saturated formula is better than a weak formula. So, I added 1/3 of the original components. Spent around $8 in this.
I was extra careful in handling the slide. Glove marks, water marks, grease marks are a problem…because they will show in the bluing, and they look ugly…ruin the job.
I cleaned the slide using a cotton and alcohol (home denaturalized alcohol), and dried everything using the same hair drier. I worked over a clean (ultra clean) cotton rag on my bench.
"Cooked" the slide for an hour inside the bath at 295 deg. The bath was over saturated and the pan almost filled, this made the whole process a bit complicated…
After I took it out the bath, I submerged in a bucket of clean water with baking soda to neutralize the effects of the salts. Dried it well and the "marinated" it inside a zip lock bag with Mobil 1 oil for 3 hours.
Took is out and dried all the oil with paper towels.
and voila…it is black…
(next to a M915 slide I got recently)
I am really happy how it turn out. It is a very nice flat/sating black.
Almost there...
