As I promised, I send you some better pictures of my portable press.
All the press is made of aluminium anticorodal, an aeronautical league, the cylinders are cm. 52 wide and have a diameter of mm. 140.
If I need to move the press I take off the bed (cm. 130x52) that weights nearly 18 Kg. and I deplace everything by myself. The press itself weights around 30 kg. So I thing the total weight is less than 50 kg. (less than lb 111).
