Cold Air Return Grate

I needed to build a new cold air return grate for my foyer remodel since the old one was made of pine. I wanted the grate to match the hardwood floors. I started out by making a box joint jig to make the slotted cuts in each strip of wood. The strips of wood all have dado cuts half way through so they can all be joined together to make the intersecting crosses. I started all of the cuts in the center and worked my way to the edges that way the spacing really was not critical along the outer perimeter. Then the top and bottom are laminated with 1/4” oak to hide all of the joints and overlap the opening in the floor. I ended up with about $25 worth of materials but lots of hours. It fit the opening perfet and works great.

Nice job, very neat. Now you’re actually going to walk on it? No shoes, just socks.

It is strong enough to jump and down on it. Even with shoes on.

I like the look a lot, and I need to do this for my gratings. I’m curious though about what you mean by laminating the top and bottom. Not sure how you are hiding all the joints.

JohnVV, on the outer frame of the grate I cut the dado cuts full depth. The strips of wood intersect the outer edge pieces approx. 1”. The 1/4” oak laminated on the top and bottom of the outer edges not only hide the joints but also give a little extra support. I wish I could send you a picture of what I am talking about.

Ok, that makes sense. I see what you did. A lot easier than 100 mortises!
