advice asked for my press

[Fredistiller]

Hi,

I'm currently working on my SS press. I'll use it for elderberries, grapes and apples. Any advices from experienced people would be much appreciated.
For apples I read that it's better to make "cakes" and and using slats instead of using a basket That's why, in addition to win storage space, I make a bolted system for the vertical pipes.

Here are some specs:
Rectangle pipe of 50mm x 50mm x 2mm.
The basket (green) will be a reinforced stainless steel perforated sheet. I'll use a bag inside.

My questions are:
I hesitate which bottle jack (yellow and fully extended on the drawing) I should buy: 5-8-10 Tons? Does a more powerful jack works faster?
I would like to keep the dimensions as they are for storage versus volume purposes. But I'm then wondering how smaller the basket has to be compared to the tray. Does the juice spit out of the basket? If yes how much space is needed not to spill on the floor? Now I have 1 cm left and right between the basket and the tray.
