Re: winniewino & others comments
The photos that were taken of casting his and other barrels [including Golf Ball Mortars] are now included on the
www.ncagb.com website. If winniewino would like additional information etc I can be contacted through Roger at Shooting Supplies in Bromsgrove UK.
I’m not sure if he had a Bloomfield or Monk barrel, however pictures of both are in the photo & video gallery together with one showing a 2 mm fuse [supplied by wireless fireworks in the UK] in a 1/8” hole ~ it shows my cannon (20 mm bore] which I never seem to get round to finishing the polishing.
Other photos shows the vent working, the videos especially in slow motion create loads of laughs.
I admit they do need cleaning which is usually done by putting a suitably marked pricker in the vent to show the cannon is clear.
Interesting comments on why the vent is drilled at an angle, we figured it was to keep some ‘meat’ at the end of the bore. Ours are circa 20 deg off the vertical; ignore the red dots on the photos they were for illustrative purposes & they never got cleaned off !.
We did not consider that the cannon barrels we had cast were really suitable for anything else than fuse as the barrel and carriage are true to scale.
Fuse diameter. Some members use 1/8” fuse, they work, but a bit incongruous in this application.
FYI we had some aluminium carriage wheels cast that enabled the same barrel to be fitted on a carriage ~~ photos of these will be under the ¼ scale wheels thread.
