Try rusty bluing.

Ingredients? - Process?

The final major components for a project.

Ingredients? - Process?

For example

1. classic, with steam box (tested personally)

The main reagent is iron nitrate. You can do it yourself, but I don't recommend it. It's easier to buy ready-made.


FeO + 4HNO3 → Fe(NO3)3 + NO2 + 2H2O,

Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O,

Fe3O4 + 10HNO3 → 3Fe(NO3)3 + NO2 + 5H2O.

2. recipe with zinc chloride and ammonium + Alcohol + hydrogen peroxide.

An article I was reading in the Guardian today....

They have discovered that the Christmas period is associated with a significantly increased risk of penile fractures – a medical emergency in which the erection-producing regions of the penis snap, usually as a result of forceful bending during over-enthusiastic sexual intercourse.

“This injury tends to occur during wild sex – particularly in positions where you’re not in direct eye contact [with your partner], such as the reverse cowgirl,” said Dr Nikolaos Pyrgides, a urologist at the Ludwig Maximilian University of Munich, who led the research.

The fractures are often heralded by an audible crack, followed by severe pain, rapid loss of erection and severe swelling and bruising. “When [patients] present to their doctor their penis often looks like an eggplant,” Pyrgides said.

It's an interesting read.

Risk of penile fractures rises at Christmas, doctors find

Researchers suspect euphoria and intimacy of season may be behind spike in cases

Doctor, take away the pain but leave the swelling

In terms of durability, rust bluing is approximately equal to bluing in molten alkali or gray parkerization.

In any case, oil impregnation is necessary and requires regular renewal.

And cold bluing is selenium salts that are weak to abrasive and water (several microns thick). Roughly speaking, commercialized hocus pocus, nothing more.

Rust bluing is black magnetite, it is this that generates a sheaf of sparks if you polish a thick layer of black rust. Hard and black.

re: fume bluing…..There was a post on the airgunbbs about rust or fume bluing.

here’s a post from there, hope it’s okay to post. It’s not my post, the only other thing I read elsewhere was to boil it in deionised water

Ok Folks now for the fun bit.

After reading everything I could on Cold Rust Bluing, and having spoken to someone who used to do it, here's what I've found out and been up to.

There are two ways of cold rust bluing I've gone for the easiest and safest way -- which involves rusting the gun in acid fumes.

This method was posted on another gun forum by a chap called Owain Glyndwr (respect to you sir

)

First off you need to bung the barrel to stop rust forming in it, then you need a tank to boil water in here's mine with the action at boil.

I cleaned the action with cellulose thiners then boiled it in water to clean off any remaining oil before putting in the sweat box.

Here's my very expensive sweat box with the action in it.

http://i1138.photobucket.com/albums/...3012006281.jpg

The container in the sweat box contains Mortar cleaning acid (Hydrochloric Acid 16%).
Then I just put a lid on it and left it.

http://i1138.photobucket.com/albums/...3012006283.jpg

After fourteen hours I took the lid off and found this.

Which was just what I wanted to see.

Next I boiled the action in the tank until all the rust had turned black and then I cooled it off in cold water for a while to harden the black rust off.

Then I wire wooled the action to remove all the loose black rust until it looked like this.

Then I wiped it all over with a damp cloth to remove any dirt and put it back in the sweat box for 23 hours after which it looked like this.

After boiling and wire wooling it looked like this.

Then I put it back into the sweat box to rust again, I'll carry on rusting until it stops forming rust.
Then I'll soak it in oil for a few days to cure it.

I've been wearing rubber gloves when handling the action, this is recommended to stop oil from your skin getting onto the steel.

My one balls up was putting the acid directly under the action as the fumes condensed on the steel and stoped the underside rusting -- sorted now.


I'll post some more pictures when finished.

The post would make a lot more sense, and be easier to follow, if you uploaded the photos.

Spares for the 2511, I wanted a spare chain but found this lot on ebay for £35, from a shop this lot might be £200 Noted that the chains are 1.1mm and bars are 1.3mm gauge so cant be used together.
They sent it fast and appears to be from a shop not too far from me so will try them next time I need to buy stuff.

Such a shame that's all gone altogether I think Tangye are still going.
Property developers and town planners have done far more damage than Hitler ever did.

We used to to use their manual pumps for pressure testing pipe work ( retired 11 years ago) very good gear.

Nothing else.


I presume the smaller boxes had all been used up and the bubble pack had all been popped.

Another Anglepoise light from the local free stuff group on Facebook, from a nice old chap who'd sold his house and presumably wanted to get rid of broken stuff. "I hope you can get it working", he said, and I smugly figured that as it's only a plug, wire, switch, bulb holder and bulb, I'd probably be able to.

Turns out it was the fuse in the plug, so it was an easier fix than I expected. I just need to get a plastic "nut" to hold the switch in place as that is missing. The switch does feel a bit weird but while it's not held in place, I can't tell whether it really is or not.

Today i never acquired, went to my local scrapyard this week and put my name on a brand new Sealey engine hoist. Today i went to pick it up and found it at the top of the heap all bent from the yard grab my man finished work early for Christmas and his mate never knew i wanted it.

Oh, this is what the new air tax looks like!?

A few good friends have arrived, this is what they left me with.

Yes, that's right. I have no idea what is there.


But I have a friend for a few days.

 

[The_Yellow_Ardvark]

Plus it is not true.

I have not lost them, unlike some I could mention.

I have found them
