Well, after dadoing enough pieces for 3 beehives (96 pieces, dadoed both ends), I discovered my jig (which had to be set for each batch) was out ~1/64”. After 5 dados on each piece that makes the measurement out 5/64”, over 1/16”! Needless to say they didn’t fit together very well. I managed to make short pieces out of the long ones but over all, 3/4 of ~$150 worth of wood is now on the burn pile.
So I thought it was about time I made something that I didn’t have to set every time and take the chance of the measurements being out. So, behold, my new dado sled. It will accommodate up to 7 pieces up to 10 1/2” wide. It’s not adjustable, although the plate with the red and blue marks on it could be replaced for a different measurement. Since this is a dedicated unit I never have to change the measurements, thus never making the previous mistake again (I hope ;)).
There’s a little tear out on the last piece but that can be put inside the hive and be out of sight. Having so many pieces stacked together prevents tear out on the vast majority.
It’s all made from material I had laying around. The sled runners (I know there’s a proper name, I don’t know what it is) are red oak, the rest is 3/4 ply. The plates are 1/8” aluminum. I drilled the marked plate on my milling machine so the measurements are dead accurate. Placing the pin (on the front box) in the holes with the red marks will make the side pieces and the blue marks will make the end pieces.
I plan on ordering a couple of suitable jig clamps to mount on the front and side to hold the wood in place, but a bar clamp and wedge will have to do for now.

Forgive me, it might be that I just woke up, but how does this sled work to make dadoes? Looks like you are cutting end grain, and I thought a dado was a wide cut cross grain….

Well this certainly shows my vast expertise doesn’t it?!? I guess I’m not cutting dados, I’m using a dado blade to cut finger joints.
Thanks for the correction. I’ll get this wood working lingo down yet ;).

Well your ingenuity is showing. You had a problem and you sloved it. A rose is still a rose no matter what you call it.

Michael,
I’m still confused; I don’t see how that jig helps you make box (finger) joints.
When making said joint, there’s got to be a way to move the board an exact fixed distance sideways
repeatedly to make the sequential cuts. Google “Lynn’s Box Joint Jig” and you’ll see what I mean.
The one place I could see the jig you’re showing as being useful is for the inner cover as seen in this PDF file:

Hope that’s useful,

Gary,
There are pre-drilled holes in the metal plate that is attached to the sled, the box that holds the wood to be cut also has a metal plate with pins. That is how the box gets moved over at a set distance.
Mike, great idea making a jig to fill your specific needs.

Michael
It looks to me like you lift the whole box containing the pieces being cut and move it over, using the aluminum as your guide is that correct.
Either way great idea!

Pat,
I get it now; the first picture is loaded with boards but not loaded as it’s used. That’s partly
what was confusing me.
Good idea Michael—Mass production at its finest.

Ok, to help explain how this contraption works…
Video
My camera stopped recording after 2:45 but it shows enough to get the general idea.

After seeing the video, it cleared things up for me.
