Wannigan/Cooler Build

take the thing apart and put a good end back into the jig then see what changed ? you could have flipped the front side with the back side , I all ways mark front and back top and bottom?

That is true. I had forgot about that and it is in the instructions.

I think that the only problem with the wrong alignment is that the fingers don't align for the edges to line up. I amy be wrong, but that is what I remember.

I agree with Hobbyman

I think you accidently flipped a piece front to back. Always mark them so your marks always face each other.

I do not understand how the front/back flip will affect runout(?) on a single joint.

Now getting the opposite end to line up is understandable.

I would be suspicious of technique regarding direction of pressure of the workpiece against the fingers.

Yes it is possible I mixed something up.

Correct me if I am wrong, but my understanding is that the marked edge of board #1 should face left (from the operator's perspective). After cutting all the joints on one end of a board #1, board #1 needs to be to be flipped to do the joints on the other end of board #1 while keeping the marked edge orientation of board #1 to the operator's left.

I also understand that to cut the joints on board #2 to match, board #1 must be rotated so the marked edge of board #1 abuts the marked edge of board #2. And so on.

I have never used an I box, but have made box joints up to 12 inches long.
It is a trial and error thing and requires a homemade box joint jig. If your joints are too tight you just tap the jig one direction with a small hammer. If the joints are too loose tap in the other direction.

There are internet directions on making such jig and adjustments.
s I describe a tap - it is just that and depends a lot on how tight the jig is bolted to the miter guage.

Best wishes! I know you can do it.

That is correct. I like to do each corner as I go (usually CCW), but each to his own. I just like to see it come together corner by corner.

Not sure why the cuts are off,,,, but like I was saying if you mark top and bottom as well as the corners you should be good to go as long as nothing moves , I cant tell you how many times I flipped and spun the stupid board instead of just spinning it and had to make another .

One thing that may help ,,,is once you have them laid out ,,, set them next to each other in order and see if they line up.

very nice work!

Well, it looks like I did indeed flip or rotate a piece when I shouldn't have. A little flipping a little rotating and a little mallet and the joints all game together. I will say, however, that something must have moved because the first joint I did was a bit looser than all the others. Still, should work for this project. Thanks for the advice everyone!

So, this was the best corner on the wannigan. It is 16" long and the fingers are 1/4”wide.

I think that's a pretty good result for the iBox. There was some tear out in the cheap big box store ply (which is .192 thick), and the other corners were worse. But it doesn't matter because these joints are not structural. They are just there to hold the box together while I reinforce the inside corners with thickened epoxy fillets. The outside corners will get slightly rounded over and the whole thing will get a fiberglass/epoxy covering to make it totally water proof and strong.
