Free Plans: David Kerzel’s Hit & Miss Engine

David Kerzel has free plans for this beautiful hit & miss engine he designed.  It may look like it’s made from castings but it’s actually made from bar stock.  The cylinder has a .75-inch bore and the flywheels are 3.5-inch in diameter.  The plans also come with some well-written and very helpful construction notes.  You can find the links to download David’s plans and notes near the bottom of this web page.

Why should self-interested companies be permitted to shift the balance of fundamental liberties, risking free expression, free markets, scientific progress, consumer rights, societal stability, and the end of physical and informational want? Because somebody might be able to steal a song?
