Armstrong Breech Block Rest
In the above photograph, taken I think of a 110pr Armstrong breech loader in Canada, of a Garrison mounted gun, there are several very interesting features. The Smith’s elevating screw for instance, and the remnants of the left hand breech tangent sight. But I am particularly looking at the flat surfaced item which is attached to the top of the breech. It took me some time to work out the function of the rather complex shaped item.
The breech block, which weighed 130lbs, had to be lifted out of the breech by two strong gunners to permit swabbing of the bore from the breech aperture (also visible in the photo), then loading of the next projectile and gunpowder bag, after which the breech block was lifted back into position and screwed tightly closed prior to the next firing.
Ah….. the flat topped attachment is where the breech block was placed while the swabbing and loading took place!
So I set about making the breech block rest (as I called it) for my model.
The rest looked complex and difficult to model. The inner surface had to fit the external surface of the breech, including two convex fillets. The external surface has to fit the breech block, without denting or otherwise damaging it despite its considerable weight and frequent manhandling. And there are holes for 6 attaching screws.
Now, dear readers, I must inform you that I have only enough WordPress memory for another one or two posts and a few photographs.
The Armstrong 110pr breech loader cannon model project is almost finished.
The remaining parts, including the Smith’s elevating screw, carriage wheels, rope eye bolts and capstain were all described in the build of the Armstrong 80pr rifled muzzle loading model cannon, so I will not repeat those details for the 110 pr.
I will leave the remaining small memory for the assembled model of the 110 breech loader, in a few weeks time.
And since I will not delete any more old posts, that will be my final post. (unless WordPress changes their policy of not increasing memory limits. And I do not expect that to happen.)
In the final post I will notify you, my readers, of the site where I will post photos of future projects. Not quite yet decided, but it will NOT be WordPress.
Looking forward t your move. Great work as always and will continue to follow you where ever you end up at.
John Hows it going down there is everything ok? I hope you’re still fit and well and getting out into the workshop. I haven’t had any updates from you for quite a while, Ive checked the junk folder and can’t find anything maybe I’m not on your mailing list anymore. Regards Rich
Hi Rich, I am almost out of storage space at WordPress, and saving the little bit remaining for a final post on the Amstrong breech loader. WordPress say that the only way to get more storage is to buy a business plan which is x3 the current price. Ridiculous attitude, considering how cheap storage is these days. But there it is. I don’t even have enough space for a post on the lathe which made the Bismarck 15″ guns, which I have located in a factory in Victoria!
John Well I’m glad your ok and I’m looking forward to seeing the piece finished. I hope you find some way to resolve this problem as I’d like to see what future projects you do. Regards Rich
