Modelling A Turkish Bombard- The Pins
There are 16 pins at each end of each section of the cannon.
These were certainly used as leverage points, for very strong men with large levers to rotate the 8-9 tonne segments against each other to engage and tighten the screw.
I cannot see how the pins would have been cast with the breech and barrel. For my model I decided to make separate pins and fit them into the gap between the big rings, then insert a grub screw through both rings and the pin. The holes are then filled.
I wonder if a similar method was used in 1464. I would love to have a close look at the original cannon to figure this out. From the photographs, I can see no evidence of later insertion of pins, but neither can I see how it would have been done any other way.
The holes are now filled with wood filler, and will be sanded flush. They should be invisible after painting.
Next the painting, the stands, and some cannon balls. How to reproduce that aged copper colour…
