I have the ebook, and my only major complaint is that it doesn’t mention lathes. At all. 
Another equivalent book, The Knowledge, barely mentions lathes. 
Sometimes I’m tempted to design simple machines using the principles in the books and then release it as “practical engineering for the colonial time traveller”
