Recommended Posts

evening all sorry if this has been covered before but I could not find the info. I am reworking my rizzini o/u I have got the woodwork how I want it but now I am on to the barrel . I have removed the old blueing with wet and dry question is how clean and shiny does it need to be before I take it to the local gunsmiths to be done ( 40 pound if it's prepped 150 if he needs to do it )I have tryed the DIY kits but it was not as dark as I would like it to be :hmm: Any advise gratefully received m1

You want to get to almost a "chrome finish", so whatever wet and dry you have used, gradually use finer and finer paper so you can't see any scouring marks!

For future reference, you could have used cement cleaner (5% acid)which you can get from any builders merchants, and simply wipe off the blue from your barrels instead of using wet and dry. I stripped my barrels in under 5 minutes, and didn't have the scratches from the wet and dry to worry about afterwards. I simply finished of my prep work using 00 grade wool and ended with almost a mirror finish; Obviously any deeper scratches need rubbing down with appropriate sand paper.

Remember, though any marks or scratches in your barrels will be filled with colour by the blueing, it won't hide them. My advice would be to give it your best shot, then run it down to the gunsmith and ask his/her opinion, their experience will know when the barrels are ready for blue.

 

Take some pictures of the stages and post them on here, always good to see some DIY on here :yes:

Thanks for that :good: Looks like I have a lot more rubbing back to do then as there is some light scratches showing through where I have had to use heavier grit to try to clean the pitting marks .. Could I use one of those scotchbrite mops on a drill has any one tryed that :hmm:

Here's some pictures when I did mine.

 

I couldn't resist puting the gun back together when the barrels were stripped

And another in the stand I made so I could work on the barrels without handling them

As smooth and shine as you can possible get it. The better polish them the better the Finnish

Its all in the prep and thats the big cost labour wise,as above the smoother/chrome looking the better and keep your strokes in same direction :good:

To get the right job at the end assuming you want the mirror shine you need the metal absolutely gleaming with no pits, marks, scratches whatsover before it goes near the tanks

 

Once blacked the finish will highlight every little mark like neon.

 

If you want a matt finish then less polishing and an acid etch looks very professional.

 

Either way you must remove every last scratch and pit from the steel first.

I would disagree with that you need to rotate your strokes to keep things straight, if you polish in only one direction you will leave flats which can look dreadful, particularly if you have had to draw file first to remove pitting.

 

Be certain to remove every mark from the previous grade of paper/wheel every single time!

 

Each to their own though
