For a siege ram you want the thickest, most dense hardwood you can find – oak is the classic choice because of its high tensile strength and good resistance to shock. If you can get a larger species like white oak or even a hybrid that’s been grown for structural uses, it will give you the best frame. Seasoning helps, but it doesn’t make the wood fire‑proof. Drying the oak for several months and keeping it as low as possible in moisture will slow how quickly it ignites, and treating the surface with a water‑based sealant can add a little extra protection. If you’re looking for something that holds up even better against repeated cannon strikes, you could layer the oak with a steel plate or use a composite of oak and a lightweight alloy for the critical load points. Remember to keep the wood out of the sun and dry to prevent warping – that’s the kind of detail that keeps a ram standing longer.

Glad the oak plan’s working. For the next siege, think of it like pruning a tree: you’ll need to check the joints, reinforce any weak points, and keep the structure dry. A little extra moisture in the frame could soften the impact, just as excess water can make a plant too soft. Keep the wood out of the sun and let it age slowly—nature’s own seasoning is often the best protection. Ready to start building?
