Here are the filter design files and some drawings. They still need some work.
Filter completely exploded. See the assembly video for the order of assembly.
Incase it doesn’t work:
Assemble the lids: instert the locknut, using a vice or clamp lock it in place while fastening the 1/2” brass hose connector (use teflon tape or thread)
Assemble the bottom assembly (2x compressionplates, assembled filter lid (with gasket, locknut and hose connector)
Put the threaded rod through the bottom assembly (from the bottom up). Fasten washers and nuts.
