416WSM on Siamese Mauser & 416/348Ackley Improved on Martini

When I rust blued my 9.3X64B and 222Rimmed on a Martini Cadet I left the solution on overnight. This created a deep matt blue that is very durable.
I did a bit more reading of the Neidner Cold Bluing process. They only left the solution on for 3hrs and completed 2 cycles per day. They repeated up to 12 cycles.
The Omark 44 barreled action (top) had 4 cycles over the weekend. Below it is the raw 416WSM in white as a comparison. The short cycles is producing a gloss/satin finish, as it does not etch the base metal as deeply.

I also did the cross bolt screws for the 416WSM at the same time.

The longer the solution is on the more it reacts, causing the rusting, which in turn is etching or pitting the surface, giving a deep Matt finish, I do two rust /boil cycles a day for as many days as I need to get an even deep blue over the entire firearm. This may take longer but gives a glossier colour, it also helps to even out the colour as different steels with react at different rates. I don’t do much hot bluing anymore as I like the control rust bluing gives me

The chemicals used in hot bluing are much nastier. I would not be doing hot bluing in our kitchen.
I was working on a 5hr cycle over the weekend, which means the chemical was actively on the metal for about 4hrs.

I’ve got burners and tanks on a stand, the vapour from hot bluing will rust metal so not the sort of thing to do inside unless you have a very understanding partner

Now I know it was a stupid idea but I gave it a shot!
Currently I am in Thaland for work. I travelled up to Bangkok for the weekend and decided to see if the local gun trade knew anything about Siamese Mausers and if there were any spare parts floating around.
All the gun shops are located South of the centre of Bangkok and clustered in one small area. Most guns for sale are automatic handguns with a few rifles and shotguns. All focused on target shooting as I don't think hunting is legal, and appart from the far north there is very little wilderness for game animals.
None of the gun shops had any idea what a Siamese Mauser was but they did eventually point me to a gun repair shop down a dark alley that was also fragrent. Found it, and there were a couple of old Thai guys running the show. Short answer was nothing in Thailand all was sold to the trade. Thank god for smart phones as at least they could understand exactly what I was after.
 
For those who are not familiar with the rust blue method. Heres what it looks like after 4 hours of the solution on, just before boiling in water. This was the 6th time it had been rusted.

Hey bloke that is now a rusted piece of junk, how much are going to pay me to take it off your hands. :ROFLMAO: :ROFLMAO:


On a serious note, how come you didn't take the front sights off so all the barrel would be blued?

The barrel is .600 diameter at the muzzle. That leaves 0.092" (2.3mm) to drill and tap, or more seriously 1.8mm to be safe = bugger all threads when you consider drill and tap points. The sights are soft soldered on like most express sights are, alot easier to solder in the white.

Here is that "rusty piece of junk" after boiling and carding with steel wool for the 6th time.

That is one sweet looking rifle. Love the depth of that bluing.
Thanks for explaining about the sights. Knew there would be a reason for it.

Everyone always thinks about the worst thing that can happen, maybe ask yourself what's the best outcome that could happen?
