hey just bought a humidex. the cut needed in the joist is 6 1/4''. no where around here has that hole saw available, what can i use to make it larger, i used a 6' hole saw already, pls help, a snow storm is coming...lol
Not sure what a Humidex is, but I can assure you that there is rarely a circumstance that you can cut a 6"+ hole in a joist! 1/3 the total depth of the joist is the max, with no less than 2" of wood remaining top and bottom.
