Yeah, fire it up like a hot‑rod. Snap the heads into a quick‑release collar, use a small ball‑bearing cam to lock the head in place, and keep the shank just a little off‑center so you can twist it straight out. Add a spring‑loaded latch on the opposite side so when you spin the whole thing it snaps into the next head in under a second. Don’t worry about perfect fit right now – get the mechanism moving, then polish the tolerances. That’s how you keep the build moving faster than a squirrel on espresso.
