Welcome back aboard Spiffy, our 44ft hurricane-damaged Antares catamaran. This week I’m trying to answer two big questions: can I actually thermoform 10mm (3/8") acrylic with compound curves for our new windows, and is Spiffy’s cabin top warped from the hurricane? I’ve been called insane for attempting DIY windows this thick, but when a full set of six is around $20,000, I’m willing to build an overengineered solution and find out the hard way. Before the oven madness, I chased down the eyebrow-mystery from last week. A quick template test at Marine Craft (surrounded by other Antares boats) confirmed the cabin top isn’t warped—huge relief, because it means our shapes are still “factory-ish” and I’m not fighting a bent boat. Then it was straight into building a ginormous top-loading electric oven: aluminum construction, rockwool insulation, fin heaters controlled by PID controllers, high-temp wiring, and plans for fans to prevent hot spots. I also CNC-cut a perforated heat deflector—over a thousand holes—because I’m not drilling that by hand. We didn’t get to the actual acrylic forming yet (weather and missing parts had opinions), but the oven is real, it opens and closes, and next week we’ll see if this whole “giant DIY acrylic window oven” idea is genius… or just chaos with rivets.
