Companion site for the book by Thomas Jackson
Weigh it right,
every batch.
Sixteen calculators that turn any batch size into exact weights, a bench mode for the workshop, printable batch sheets, and supplier and regulatory notes that stay current after the book is printed.
Each code creates one account and works once. It is printed on the companion page inside the back of the book.
