This is the press I made this year.
The uprights are a handily placed, multi-stemmed Blakely's Red Gum.
The cross beam I made with my chainsaw from yellow box hardwood.
The racks are sealed plywood.
The cloths are nylon mossie net.
The jack is 6 ton.
The collecting tray is made from concrete.
I measured a load, 24kg apples gave 15.5kg juice so a yield about 65% by weight.
It takes 30min for a load including milling fruit, so I can do about 30L/hr.
I could take bigger loads but it does quite well for me the way it is.
The idea was to make a press with a minimum expenditure. The total spent was a bit over $100. I have pressed about 250L so far with another 400L to come.
