Thanks for the photos. I am not a metal worker and recently built a naval carriage for my half scale 1841 six pounder. The wood parts of the carriage, while not a piece of cake, I could make. When it came to the trunnion caps I took some flat stock and after hours of heating and pounding, using a vice and a piece of pipe as as the guide, I got my trunnions hammered out. With a little grinding they look fine. I would have loved to buy them though and saved the time. Does anyone manufacture these things like this? It seems they would be fairly cheap for someone with the right equipment to make and sell to people like me who had trouble shelling out $100 or more for a set of cast iron trunnion caps. THanks againg for the great forum. I don't post often but I read it all the time. I am working on the base for my Hern Iron Works mortar now and use this sight to gather all the info I need.
