Hey Jocks,

Here is another question from our of our site users. His name is Dick.

"I need to saw out the floor plate in a cold air return.

Normally, the entire space is cut out for the cold air to flow. However, my contractor only drilled a series of holes and now I need to saw out the wood between the holes. The drywall is installed on both sides so I must reach through the cold ir register.

What type of saw would you suggest?

I was thinking a keyhole saw. Is there a power or air saw that is small enough to get within the 3.5 inch wall and cut out the wood?"

Thanks for your help. :)

Adam

You may have to go the old fashion way, by using a hammer, & chisel.

I got some more info from Dick. He also sent some images.

"Attached is a picture of what the plate looks like. I held the camera in the wall cold air return looking down between the wall studs. The space that I have to work in is the 3.5 inches by the 13 inches between the studs. There is not enough space to get a sawsall inside the wall to saw between the holes. Also the ceiling below has drywall so I cannot saw from below. I have also attached a picture of the hole in the wall for the vent.

I appreciate the suggestions. In order to saw the plate, the saw would have to fit between the walls and reach down to the plan which is about 10-12 inches below the opening for the vent"

Thanks for your help!

I don't suppose there's enough room to get a small drill in there and drill a series of holes?
You could use a small powered screw driver wth a drill bit on it maybe.

I agree, leave it. I'm sure you will get reasonable air-flow through the large holes he's drilled. I very much doubt that he expected anyone to enlarge the opening after the drywall was installed.

Here is the final word from Dick on your feedback.

"I wanted to let you know that Frank Chaffee's (from familywoodworking.net) suggestion is probably going to work. He suggested a Fein MultiMaster. I tried one over the weekend and it seems to do the job,

Thanks for all your help and suggestions.

Dick"

Thanks for all your help guys.
