I put necessary laminate on a table, just glued slightly with spry together. Then peel-ply with a reserve. Then lay net only on the bottom. Another strip on top of tube later. All this I lay to one part of mold. From one end I connected resin inflow hose just 10cm inside on the bottom where is a net. Then I put hard smaller tube covered by vacuum film agglutinated with sealing tape along the mold. Then I lay another net strip on the top and folded all ends of laminate correctly around the hard tube, before connected vacuum hose on the other end of mold at the top between peel-ply and net. After I extracted the hard tube from the inside and slightly folded inside all laminate to cover with a top side of mold. Before covering I lay seal around a perimeter and covered with a top mold. Sealed up both ends and tautened all sides of mold together every 50cm. The I vacuumed it and everything looks great for 15 minutes.
