Abstract
A hole punching machine for use on wet or damp drywall improves ventilation behind the drywall for drying purposes. The machine includes a base position on the floor and against the wall. A pneumatic ram in the base can be extended and retracted to cut a hole in drywall, after any baseboard is removed. The hole can then be covered when the baseboard is reinstalled. The operator can activate the ram using a switch, while standing.
