Another Model Cannon Builder
One of my US readers has made a model rifled cannon, an Armstrong 110lb breech loader, 1:9 scale. And it looks superb! Best of all, he has made 2 videos of firing it. I definitely recommend checking out the build and the firing in the link below.
I will substantially copy the rifling setup which Jeff used. My sincere thanks to him for the information. (ps. although Jeff’s setup was tempting, eventually I used a CNC rotary table and CNC mill to do the rifling. See later posts.)
John I agree the videos are quite impressive, I like the rifling process that he used and a beautiful job. Was very interesting in the increase in accuracy after the change to the projectile.
HI John, was looking at a couple of other YouTube videos and found this one with an interesting way of getting the cutter, reminded me of Nevil’s use of a circular saw blade to make a parting tool. https://www.youtube.com/watch?v=IvwOcrC6cdU
Thanks Brendan. Cold saw steel would be better. I have a couple of broken cold saw blades, and I think that they would be about the right thickness.(2.5-3mm). I like his use of threaded rod and drill to power the process. Still thinking about Rudi’s suggestion of pushing through a piloted cutter. Made 2 barrels so far. Not entirely happy with either of them, but they can be used to test the rifling methods.
