The 80 pr muzzle loading cannon was supplied to the colonial government of Victoria on a wooden traversing platform with a 5º slope.
I assumed that the slope was the means of absorbing the recoil.
The later iron platforms (from about 1875) had a 4º slope and hydraulic recoil control.
But, I was recently informed that there was a wooden “compressor”, which acted as a primitive brake, to reduce the distance of the barrel and carriage recoil. And that there was a compressor at the Flagstaff Hill Museum, Warrnambool, Victoria.
In fact I had previously seen the compressor, but neither I, nor I suspect the museum staff, really understood then how the compressor functioned.
Using Victorian Collections photographs published on the web, my own photographs, information from “The Artillerest” Peter Webster, some old drawings of wooden carriages and platforms, and a Google book “British Smooth Bore Artillery” by David McConnell, and a fair bit of deduction, I think that I have finally worked it out.
Firstly, the Victorian Collections photographs…
Now to make one at 1:10 scale.
P.s. reader Jeff sent me some photos of a recoil control system used in 19th century USA, where a large metal screw clamp was utilised in these rifled muzzle loaders
