A bad HDPE weld looks exactly like a good one. That's the whole problem — and it's why most people ruin expensive sheet before they ever finish a boat.
We're Legacy HDPE, out of Rozet, Wyoming. We extrude our own sheet, cut boat kits on our CNC, and we've built around 70 HDPE boats. Everything we've learned doing it is in here.
Inside: the complete Legacy HDPE Fabrication Manual — prep, tacking, and a written procedure for every joint on a boat — plus troubleshooting, build logs from other members, and straight answers from our shop floor.
You can get certified too. You weld five coupons we cut and ship you, send them back, and we break them ourselves. Pass, and you go on the public registry.
Whether you're building your first boat or welding HDPE for a living — this is where you learn to do it right.
