(solved) Weak suction on Exposure Vacuum lid
I have been wanting to create an exposure unit and tried this one. However I am unable to get the lid to work. I have sealed the all air pockets ( i hope) with duct tape on the wooded frame. I have a 6cfm vacuum pump. I see the blanket being sucked to the glass but not fully flat . Do I need a bigger pump? Thanks for your input.
