It's that easy...

for the manufacturing of rounded parts, only one template is needed (no counter-template necessary)
the template and the attached work piece layers are inserted into the vacuum pouch
the pouch is sealed with a wooden bar and clamps (from the own workshop)
the vacuum pump is turned on and the vacuum pressure inside the pouch evenly shapes the inserted layers along the template
after completion of the pressing cycle, the vacuum pump is turned off, and the finished work piece is taken out of the vacuum pouch
