Counterpressure bottle filler plans – a start

A fellow in Australia wrote looking for plans for the counterpressure filler.  So I’ve started with the one “special” part in the core filler itself, and made a link in the sidebar with an engineering print.  It’s the machined plastic part that allows CO2 and cider to enter the bottom of the bottle through a long thin tube, and allows CO2 to escape slowly from the headspace of the bottle while the cider is flowing in. This one requires the use of a metal lathe; I have a notion to do another version that could be done with care in a basement using nothing more than a drill press, a good drill index, and a pipe tap.
