Spent the better part of the afternoon dealing with "gridlock" (made this return air grill):

very nice, what's the spacing size?

Also, is it dadoed?

Nice 3D effect in the picture as you scroll down.

Thats not easy to do without a thickness sander of some kind. Did you make a new purchase you would like to share with us?

You are going to post the set up pics sooner or later so lets just cut to the chase.

I would do that with a box joint set up with the miter gauge on the table saw. An auxiliary fence on the gauge, cut the half lap dado depth trough the fence, move the fence over the spacing amount and place a stick in the dado on the fence the same dimension as the dado.

Take your wide stock and cut a dado, move it on top of the stick protruding from the fence, cut again and again and again.

Rip and size the sticks to fit the dado.

Something like that?

Why do we have to play this game Bass? You could just post all your pics the first time.

10-Q,

The grill is 6x32" so I went with a 1-1/2" grid (goes in to both 6 and 32 nicely).

It is dadoed.

No special sander... just tight tolerances.

I was in a hurry and took no process pics this time.

You have it pretty well down. I do have some extra parts I cut and can post some pics of those later... that will hint at the process... don't mean to be so cryptic.

Mo later,

Cheers,

Bass

I know you better than that.

You love this game and wish it to live a long life. I'm on to you sir Bass.

Here are a couple more pics... a close up showing the "purlin" ends and one of the 1x2 dadoed and a rip that is a main "joist" and a couple of the purlins.
