My customer was growing herbs and making alcohol-extracted tinctures from them. He needed a press to squeeze the fluid from the herb-alcohol infusion. He later customized the press himself by wraping the wheel spokes in leather and fastening a silver dollar to the wheel hub. It is the smallest press I've made.
This type of press, while more costly than other hydraulic presses online, is very heavy duty, develops a lot of pressure and can be customized to the size you need.
Not making these anymore
