need help with my cannon build

[mtt849]

Can anyone give my advice on trunnion install idea's? This barrel is 20" long. Machine out of 1018 steel 5" round blank. The barrel is 75% machined in these pics and i still have some detailing to do. The cascable will be threaded in to rear of cannon, Obviously it's only partly machined in this pic. I still need to come up with Carriage design. 1.73" bore 14"deep/ 1-5/32 x
3 1/4" Deep powder pocket. 4 7/8" O.D

Followed your links. The pictures there are literally not as large as a postage stamp, can you enlarge them?

If you have a mill and a boring head you can use the boring head set at the diameter of the barrel to cut the radius into the trunnion and then weld them into place

Hawkeye, Ctrl&+ will enlarge pictures on your screen. Ctrl & - will reduce them again. The trick is to remember how many times you clicked to enlarge, so you know how many times to click for reduce to where you were in the first place.

Well i dont own a mill, but i do have access to waterjet and i think i can set it up to cut radius off trunnion. Also the more I read, people are press fitting them and then welding. That would also help locating them on the barrel. Sounds like i need to do more research. Here are some updated pics of the finished cascable.If anyone has detailed plans for installation that would be great.

For the browsers that use control or command + and - to change size usually doing control or command and 0 will go back to the default size.

why don't you just scale up or down a prototype you like that is suitable for your tube?

I have 1:12 scale Model 1841 42 pounder USS Cairo naval carriage plans if you want them, or you can probably find those with a google search.
