I don't know much about presses but depending on cost, I'd probabally try to built one too. It shouldn't be that hard. Considering presses can cost close to $1000, I'd consider converting a harbor freight shop press to press the cider.
I don't use a press though, I just use the cheese cloth in the primary that way I dont have to rack as many times to get the sediment out.
Years back, when grandma and grandpa used to make cider, they had a very old, probabally antique, cider press. It looked like a H-frame hydraulic press but had the screw instead. It pressed a large plate down into a wooded barrel that had a slight gap inbetween the boards that let the juices flow into into a trough and then into a bucket.
It was lagged to the concrete floor so only one person was needed.
Wow ... mine came & went about a month ago. Season over & done.
Where are you located at??
I still had about 50% red ones still on the vine when I picked these, so they will be ripening here through out the next week or so.
Are you sure you are talking blackberries or black rasberries??? I know I cant tell the difference at first glance. The only way I tell 'em appart is that the black rasberries are ripe about a month ahead of the blackberries.
I'd have put them in a pie myself.
Duff,
Are you using plans from the internet or playing it by ear? There are lots of plans out there. Some folks sell them, others give 'em away. There's a u-tube of a guy who modified a Harbor Freight arbor press to use as a cider press. In fact, he just made some parts that can be set on the press for the cider and removed so the press can still be used for its primary function. He went with the "cheese" method, where he used pressing cloths to make cheeses of the pulp and doesn't then have to make a barrel to hold the pulp....the cloth takes care of the sideways pressure. That looked pretty neat, but he bought the plastic tray and some pressing plates from a place that sells complete presses, and I think those parts might be kind of expensive.
