Sure, I’ve made a few makeshift towers in the past, but a full‑scale siege tower that can take a battering ram and still roll with troops is a different beast. Here’s a quick outline that might work, with a touch of unconventional flair. Start with a sturdy frame: two long, 8‑foot beams for the sides, joined at the top by a third beam that will hold the troop deck. Use 2×4s treated for rot, but if you want extra strength, replace the top beam with a 2×6 or even a steel angle iron—my cousin’s old auto repair shop has a few that fit. Cross‑bracing every 2 feet with 2×2s at 45‑degree angles; this keeps the hull from racking under impact. The wheels are the trickiest part. Standard 2‑foot steel wheels just won’t cut it; the tower has to handle weight plus the shock of a battering ram. Mount each wheel on a short axle with a leaf‑spring or two on either side to absorb the impact. If you’re into unconventional tools, I’ve found that a set of old automotive leaf springs from a car can be repurposed to give each wheel a little give—think of it as a crude suspension system. The troop deck should be 3 feet high, with a steel rail on each side to keep people from falling off. Use a heavy‑gauge steel bar across the front and back as a loading rail; bolt the front rail to a pivot that can be locked when you’re rolling and unlocked when you want to unload. You might also want a small hydraulic jack system—just a manual lever‑pump type, something that can lift the front of the tower when you need to slide the troops out, instead of relying on a jury‑rigged wedge that will probably fail under pressure. For the battering resistance, line the outside of the frame with a 6‑in‑thick layer of oak and add a 2‑in‑thick layer of iron or steel plate on the front and sides. The rear can be lighter—just the frame. When the ram hits, the front plate will absorb most of the force, and the wood will flex a little instead of splintering. Finally, don’t forget the morale boost: paint the tower a dull gray with a few stripes of bright yellow or red, so the defenders can see it from a distance but it still blends into the siege environment. It’s a lot of work, but a tower built to these specs should survive a decent battering ram and get your troops across. Just remember to keep an eye on the wheels and the suspension; that’s where the real failure usually happens.

Glad it feels right. I’ll make sure the wheels are heavy, the springs tight, and keep a spare wheel stashed in the back. If they set a trap, we can roll that spare out in a heartbeat. Thanks, and good luck on your side of the road.
