The best example of how to rifle a blind hole, like you would have in a muzzle loader, that I know of is contained in a series of articles at Greybeards Outdoors Cannon Forum.  These guys are mostly American and deal a lot in full size cannons, but there is a fair percentage of scale model makers (including one of the moderators) and often a lot of info that just cannot be obtained anywhere else on the subject of building muzzle loading cannon.
 
Please see the following address for info on how to make a rifling machine.

Hi guys,
I came across this in an old(ish) book and thought it might be interesting, from a metallurgical point of view of course.

Thanks, the rifling sounds straight forward then, but I doubt that I'd be making a working weapon.  However, it it does need to look right when one looks down the barrel.

I used to be interested in 1/10 scale rifles. An acquaintance of mine was building a WW1 13 pounder in 1/5th scale and showed it at a local model show. He was nicked and given 6 months by the local beaks. He actually did 9 months in the lockup as he then went to Crown Court where the Judge directed a Not Guilty verdict as the gun was incomplete, could not chamber any known round and the use by the local police of a technicality of being a dismantled weapon was ridiculous. Had he finished the thing before he showed it and had sent it to a proof house and got a certificate of ‘Inability to Prove’ it could not have been a gun. By the way a certificate of ‘Deactivation’ is no good because to give this it means that the thing must at onetime been able to fire.

When he asked, in court, for the thing back, as it was not a gun, he found that the ‘beaks’ had ordered its destruction along with all his books, drawings etc about guns. The Prosecution claimed that the man ‘had an unhealthy interest in guns’.  Her honour the judge nearly ate her own wig in her anger. So be warned. Those who now manage us do not know or care about the law. I got rid of all my books PDQ on guns gun-smithing and any related subject I trashed all my models etc.

I am searching my memory for this one, but I think it was during the 1980s that ME published an article by a reader who had built his own .22 competition pistol. The usual rifling twist for a .22 is one turn in 14 inches, and I seem to remember the rifling was produced by using 14 tpi gearing set up backwards (with the smallest gear wheel at the leadscrew end). The lathe was then driven from the leadscrew - possibly by turning it by hand.
I think the grooves were cut one at a time with a long boring tool of the writer's own design.
Maybe someone with a better memory than mine could dig out the article - if only to prove me wrong on the details!

Hi
 
A quick question re this page, is anyone else getting a phantom picture frame being displayed that covers some of the above posts and stops access to parts of the page under it??
 
Is this yet another quirk/problem/frustration associated with this site.
 
Cheers

Yes Martin ,  it goes from the third line of Speedy's post to just below the header on Dougie Swan's post, saw it there last night, Thought odd, but I'm on a new old computer, and I don't know if it has any bugs and gremlins, but seeing I'm not the only one, I seem to be OK that way,I don't tend to worry too much about little hitches.

Hi Ian
 
Thanks for that as I was wondering whether I had a gremlin lurking in the bowels of my system!! I only really noticed it when I tried to access something within the boundary.
 
Minor gripes over the real thing is that Dougie's rail gun is a triumph of model engineering. I could never aspire to producing something of this complexity and quality. So I will have to sit back and just admire the finished result of his dedication and hard work.
 
Cheers

Kwil have a look at the words 'Eccentric Engineering on this page.  The frame starts just above those words ind it passes between the 'ee' in Engineering.

Dear Mr Dougie Swan,
 
Uploaded a photo album containing some photo's of an 1887 155mm Howitzer manufactured by the De-Bange company. Modeled at 1 3/4" - 1ft for fitment onto a Pechott Well Wagon in 3 1/2" gauge. Completed last year. No where near your masterpiece. You need to look at doing the Pechott wagon mounted naval rail gun next !
 
Regards,
 
 
Steve.

Mr. Swan
 
I joined this sight after seeing your incredible work on you miniature cannons.  Is the coastal defense QF 6" gun based on the J.H.Pollard plans from 1912?
 
I am trying to figure out the handle mounted on the left side of the gun that looks like it is on a shaft that pass to the right side and is connected to a spring. I'm guess this was a manual ejector?
 
BTW Love the rail gun work too.

if you guys ever want to model a pistol can I suggest modelling, even at 1:1 scale, a Very Signalling Pistol. the type used in WW2 to fire recognition colours.
In australia you do not need to licence a Very Pistol at all so it would make a quite interesting model engineering exercise and it would be legal.

While rifling is a seriously kewl project in itself, and not unlike an internal leadscrew thread, if I wanted to build a projectile firing unit I would focus on a smooth bore and a projectile which was self stabilising.
 
Gerard Bull used the same approach...however being too good at ballistics, and being ambitious can get you into a lot of trubble.

Hi Mongo and thanks for the comments.
The coastal gun is based on a picture and drawing in the book "model engineering" by Henry Greenly
The shaft you ask about is part of the ejection system, the shaft acts as a rotary trip to a spring powered ejector, the spring visible on the outside is only there to pull the trip back into the locked position when te ejector is pushed back into the closed position
Regards
Dougie

Mr Swan,
 
Thanks for the reply. I ordered a copy of the book. Is your model able to fire or is like the rail gun? Luckily here in the USA I can generate working versions.
 
What tool are you using to upset the rivet? Are you bucking them or using a squeezer?  BTW thanks for the link to the supplier, for some reason I can not find a supplier in the USA on the net for the 1/16" rivet so I might have to import them from England.
 
Have you ever done a sliding breach style of miniature cannon?
