    Is there plans for big gun cannons that can only be made by hand tools only?

    You can piece together a non-rotating Big Gun cannon using a few Clippard air parts. a MAT-2 accumulator, an MJV-2 main valve, an MPA-3 actuator, and a MAV-3 firing button. You'd also need an appropriately sized brass T-fitting for your desired caliber. For 7/32" balls you'd want 5/16 compression fittings on the top and side, and for 1/4" balls you'd want 3/8 compression fittings on the top and side. Either way, you'd need 1/8NPT on the bottom to screw into the MJV-2 valve.

    Keep in mind, that would produce a single-barrel, non-rotating Big Gun cannon. Multiple barrels can be achieved by daisy-chaining several of these together. If you want a rotating multi-barrel cannon like most battleships use, you'll need access to either a 3d printer or a drill press, band saw, and lathe.

    Thanks, have band saw out of that list and scroll saw. I’m thinking about the a 3d printer it’s just cost. I’m a father of 4 on a pension after having to give up work due to very sick kids. So every time I almost save up the pennies, something else take priority.
    My son who’s 13 already built his Dorsetshire is awaiting cannons and he’s already started on his Montana

    Sooo. I've done a good deal of reading on cannon designs for big gun warships. I am curious if there is a new design that people are moving towards or are the Indians style guns still used more often. I've got a design I created based on old plans from strike models but just trying to see what's new that will be better on space. Any thoughts or plans appreciated

    If you are considering a 3d printer, I would say go Prusa.

    Prusa machines are extraordinarily high quality, but very expensive(compared to low-cost, Chinese alternative.). The curret recommended budget machine is currently the Ender 3, the kit retails for about 180 USD, and often has big sales.

    Okay yeah Prusa isn't that cheap but is great. I go a Prusa I3MK3S kit for 300 less than the ready one.

    We are talking about 3D printers. They are really useful
