I've warned you all before that what Semroc is doing is impossible using normal production techniques, and that "Carl" is likely an alien churning out products with some kind of nanotech-based matter assembler.

Proof that this is indeed the case is right on his website. Simply search for "kit" and carefully search the first page.

Yes, this "Carl" (which I'm guessing is short for "Carluskulon 653") is using his nano-assembler to replace damaged household fixtures.
