Hi fellow countryman.. I am down near Edinburgh.. always ready to assist!

An alternate is to nitre blue using molten potassium nitrate salts.. I do this for small stuff like screws, sights and triggers.. Use a strong seamless or welded can and melt the salts in it. Be careful to put a lid on the can when reheating a solid batch as the salt will foam up and...

A "bit of string" question to be honest.. It depends on how many applications you choose to put on a barrel based on depth of colour and the character of the base metal. You don't need much and I have done about a half dozen guns from my current bottle which is about half empty.. (of which some...

Amen to that!

Diolch yn fawr...! They certainly were! QEII was "My Boss" for most of my life.. very strange not having her still here! God Save the King!

Renaissance wax is manufactured in UK by Picreator ltd.. https://www.picreator.co.uk They only sell in bulk to the trade. It is however available from a number of craft and art suppliers for about £15 (about $20) for a 200ml tub. It is very popular amongst wood turners, gemmologists and knife...

Renaissance wax was developed by the British Museum conservation department who were looking for a medium to give long term protection, but that would not chemically react with anything it was applied to and could be removed completely using a solvent. The problem with any protective medium is...

I suspect that some toilet cleaners would remove the barrel from the fouling.. ... unless of course you are using a ceramic barrel!

both...!

... look up "British Humour" when you have a moment!

Never heard of rodents attacking Black Powder, but they will eat nitro cannon powder as it is basically cellulose. We had an issue with this in Germany the 70s when several cannon charges that were stored in a forward storage bunker got damaged by rats. They had to be written off and a report...

The hole for the breech screw is made directly into the barrel. It is not on a separate breech piece. There is a breech plug, but it is part of the breech tang. The breech screw arrives ready threaded, but I suspect is an investment casting. My guess is the tapered thread in the barrel is made...

I have built one of these... The thread is V form, 11 start and tapered! The plug is 2" long and goes from .878 at the base to .830 at the top. I have no idea how TRS machines these, but I suspect is it using something like a Fuzee engine which was developed for clock making. Be aware the...

Although no doubt someone has, I would advise against it.. flashpaper is a propellent in its own right and would add to the chamber pressure beyond that which the gun was designed for. Using a whole wrap of flashpaper in addition to the normal charge of GP might just be a bit excessive. It is...

Nitration of cellulose is achieved by reacting it with concentrated nitric acid. The reaction creates a series of nitrate esters mainly mononitrocellulose, dinitrocellulose and trinitrocellulose. The percentage of each depends on the purity of the original cellulose and the concentration of the...

Nitration of cellulose is achieved by treatment with nitric and sulphuric acids. Dipping paper in Potassium Nitrate simply coats it. It does not change the cellulose in any way.. .. just sayin!

Sorry for the slow reply.. I was disagreeing with you. I don't think using toy caps and ground down match heads for priming firearms "will be ok". Primary explosives are unpredictable and liable to do the unexpected, Hence my enquiry about your level of tolerance for dangerous practices and how...

Do you also use the phrase "I didn't expect that to happen! as well..?

The dynamics of propellent burns are interesting. There are two distinct phases.. I will call them "flash through" and "grain burn". Flash through is the progress of the ignition flame through the mass of the propellent grains. Once the flash has passed through the grains, igniting the surface...

An interesting thread.. My tuppence worth.. Hardened lead was very much in vogue at the end of the muzzle loading era in UK. The .451 Rigby, Henry and Metford barrels had very shallow rifling and were designed to be used with long, flat based, paper patched antimony alloy bullets. In...
