simple Hi-Tek coating

[marky123]

Righto thanks

[Petander]

Marky, what is your alloy exactly?

I had similar results with contaminated (Nb) alloy.

Now I'm good. This thread is full of HCL wash.

Hi Petander

This is a mixture of range scrap and wheelweights.

Could be anything in there!

So why are you doing this? Wasting everybody else's time.

still trying to make it work,thanks.
Could you scrape your failed coating off with a fingernail too?

[dikman]

I could with mine. It would be worth putting a few cast into Hydrochloric Acid just to see if there is any reaction.

I'll try that.Does the acid indicate and neutralize the contaminant?

The acid will etch the surface contaminants if present, I have found that the acid does not always show a real reaction right away, but left for several hours or overnight the cast will turn dark and have a slightly rough etched surface. You must wash cast well after, and I actually do so in a bucket with some Bicarbonate Soda to kill acid. I use a 2 to 1 mix of water to acid myself if I must do the acid etch. I use a lot of wheel weights and sort by hand, I have found at least 5 different types of metal in the weights, not including zinc and steel and only 3 are usable. I find range scrap better at my range as many shoot commercial made cast. Regards Stephen

But you coated the cast successfully after the acid wash?

[Tazza]

But you coated the cast successfully after the acid wash?

He sure did, it makes for a very good surface to bind with for him. Make sure all traces of acid are gone and are dry before coating.

[Stephen Cohen]

But you coated the cast successfully after the acid wash?

Like Tazza Said, make sure to remove all traces of acid by washing well and dry cast well before coating. This method will make most questionable alloy usable but you still must make that first coat very light, in fact it should look as if it barely has any on it. Follow this grasshopper and the stares will align for you. Regards Stephen.

All that information about mystery alloys and Acid Wash is right here in this thread,many times. Why does it have to be posted over and over again?

Says the man in reply #13,952... ;^].

You know, I just found the "search thread" function that's fairly good at winnowing down the results. Before I used the "advanced search" general search function in the main tool bar, that wouldn't get me any closer than the whole thread. The "search thread" function doesn't appear until you're in the thread proper.

[Petander]

Says the man in reply #13,952... ;^].

Yes. I read the whole thread before I started.

[kevin c]

As did I, twice, and uphill both ways!

I actually did read it twice, and, before finding the search thread function, conscientiously wrote down post numbers so I could find my way back to the good stuff.

If it only takes a half second to scan a post, it'd still take nearly two hours to go through the whole thread. Actually reading each post would take more than a day straight.

How is Mr. Joe doing? Out of the hospital yet?

How is Mr. Joe doing? Out of the hospital yet?

Not yet... Was talking to him on friday.

[Warhead]

I found a bottle of dark blue that was mixxed about a year or a little more ago. Put some acetone in the bottle shook it a lot and everything seemed to mix back up o.k.ish
3 coats on some reject h&g34s. Mold had a bur making it not close all the way so these are headed to the remelt pot, but passes wipe and smash test. Very dark green color. Baked at 393f (200c for those living upside down ) for 10 minutes.

[Ausglock]

Joe has sent 2 new colours.
A new Blue and a new Purple.
Will be caoting with them over the next few days.
Watch this space...

[kevin c]

Barely a week out of hospital.

The man must have passion...
