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.

Dougie,   
               Thank you for the succinct post on your methods to make an interrupted thread.  I had considered the use of my rotary table but the use of an existing bolt and nut would save a lot of time and eliminate the alignment problems I had envisaged.

Now for the stupid question.  Where do you get your rivets?  I have often enquired here in OZ but no such luck for 1/16 rivets from the normal suppliers.

Dougie,
               Further question please.  What do you use for rivets?  I use escutcheon nails they are brass and about 1.6mm in diameter, but so tedious to put in one at a time.  Any ideas or improvements you could recommend, i cannot believe how many rivets you have on the railway gun, i remain in awe of your workmanship and patience.
 
regards

Ian,
      Yes they had a steal back (sorry buy back) in 1996 for semi auto longarms of all kinds, centrefire, rimfire and shotguns.  In 2003 they went for handguns shorter than 5 inches and bigger calibre than 38.  The only good to come from that was they formalized black powder and muzzle loading cannons in the most open category Category A.  That means as long as we keep the barrel under 1200 mm in length and it is in some way a replica of an historical muzzle loader, no issues with the government or police even if it fires a 2 inch shell.  It must be licensed but to my knowledge no one has ever been refused an application.

Taking it further, making a scale model of an artillery piece has no licensing issues whatsoever if we do not drill the fuze hole or if a scale breech loader there is no firing mechanism.  They are just scale models in the eyes of the law.  I and other makers of cannons in OZ have a great time and no legal problems.
 
Back to the making of them though, Dougie please publish a description of the procedure for making an interrupted thread. I remember a series of articles in Model Engineer in May 2005 wherein the author (David Wilcox) made a scale model of a 5.5 inch breech loader that included an interrupted thread.  I got the issue with the last part of the three part article and of course could not get the missing issues for love or money.  If anyone has the copies concerned I would love to get them.

Dougie, truly amazing work on the railway gun. 
I am based in Australia and we do not have the insane laws that England suffers from.  I have built a few muzzle loader cannons as presents for friends and for own amusement and am working on a full scale volley gun with a pintle mount.  Also have an Armstrong 64 pr in 1/10 scale on the backburner.
