the best way to get rid of pitting on a project rifle

[T 20]

Glad you're getting it sorted Mick

What are you gonna wee on now? Cos all us blokes likes to wee on something out of doors!

Hi Phil

The rusting is working that well now I don't have much time for a waz.

With the first gun I fume blued (Rusty 77) I was rusting for 24 hours before boiling --- with the rusting tank inside my heated cabinet I'm having to boil 3 times a day.

The rusting time can be varied by altering the temperature and I'm finding a nice slow low temperature rusting is better than a quick rusting at high temperature --- this ties in better with my working day.

A slow rusting also makes it easier to catch the rust at the right time to boil --- you get a longer period between the rust forming and pitting developing.

A few of the lads who attended the Boinger Bash we're interested in how this process worked but I wasn't able to show them last year due to the hit and miss nature of the rust forming.
Now I'm able to pretty we'll predict the rusting period we can have a bit of a play this year and a quick demo of fume bluing.

I just hope folks don't laugh at my boiling tank for small parts --- it looks just like an electric wok.



All the best Mick

Mick keep us updated with your progress
how do you know when to start boiling and for how long do you boil.
i have taken a few days off from sanding my action i was getting pissed off .

are you taking plenty of pictures of the process with this rifle you are doing now
cheers

Great stuff.. the first thing I did when I moved into this new house was nab the electric fire for my shed!!

Not that it is really suitable in this instance (due to cost), but where the finances makes sense laser welding can be used to fill the pits convincingly. You will still need to file down afterwards of course, but you won't be filing away 'good' metal to try and disguise the pits. The likes of Carr's Welding are also RFDs so can handle firearms repairs http://www.carrswelding.co.uk/firearms.html I'm sure others also exist.

Thanks For the link ash.
The rifle is just an open sight plinker and not worth investing that much into it.
I have replaced the spring and the breech seal that's about all I want to spend.

I have a few of those open sighted plinkers myself... but I wouldn't shell out for pit repairs either on them. Good to know for shotty barrels though, and I may be tempted with getting a hammer gun I recently purchased, which has a couple of 'mild' patches on the outsides, zapped.

Hi David

This gives a good idea of what you need to see before you rust : -

We're creating the rust in a different way to Mr Pottersfield but the rust formation and boiling time is just the same.

The powered wire brush is a bit of a no go for airguns as their actions tend to be a bit more complicated than that of a cartridge rifle or shotgun so I stick with wire wool.


I'm not bluing an action at present, I'm bluing 6" lengths of 12mm hydraulic pipe as a test --- these make excellent test pieces as you can spin them up in a drill to polish them.
Doing a few test pieces is worth trying as it gets you used to the process and also shows up any problems before you move on to a gun --- so far my test pieces have shown that my new heated cabinet is scrap and that I need to build a bigger one.

another small fan heater came into my possession today, Im wondering if a tank within a tank would be better idea - Im thinking insulated box with my big tupperware box inside, fan heater, or electric fire sitting beside the insulated box - and in summer - paint it black!

Hi Mick I watched the video thanks for the link.
The guy made it look easy with all the right tools and equipment.
What's was wrong with your tank that your test pieces never worked out.

Hi David

I made my heated cabinet out of an old bath with a radiator in it like this :-

http://i1138.photobucket.com/albums/...2032012545.jpg

I thought that with the door fitted the area above the radiator would work as a big heated rusting tank, but it didn't, as no rust formed on the test pieces.

So I put a rusting tank inside the heated cabinet above the radiator :-

And inside this are my test pieces rusting away :-

As you can see they're already pretty well on their way to being blued





All the best Mick

Mick it looks like you have cracked it for cold weather rust bluing.
I will keep sanding away till Donald gets set up and I can see how it is done.
I have sourced a small two hob camping gas stove for the boiling I just need to find a suitable
Metal box to boil in ..
I will have to do it outside as my shed Is metal so no good for rusting.

How do you stop the action from rusting on the inside can you stuff it with rags or something like that

Nice bit of improvisation. I guess something like 2714099703 on fleabay would be even more ideal if the price was right.

I could not get the flea bay link to work.
