How It's Made S25 E7
Handcrafted Skis, Septic Tanks, Hydroformed Chassis Parts, Aquarium Windows

Wooden cores are layered with reinforcing materials, bases and edges before being pressed and shaped into handcrafted skis. Tank bodies are moulded or cast and fitted with access openings and internal partitions; high-pressure fluid forces metal blanks into dies to create lightweight chassis parts; and thick transparent panels are cast, machined and polished into aquarium windows.
