First, let me thank everybody for the input on the wood type I seem to using for this project. Probably southern yellow pine.

I have the 3 boards (~12x84x1.5)ready for glue up. I am not using breadboard ends. My plan is to either use biscuits or some kind of spline for greater strength and alignment. I'm not quite sure here so any input would be appreciated.

I also plan to put boards across the bottom of the top, about every 2 feet or so. Probably overkill, but I do want this to last a long time.

The final product should look sort of like this:

Yeah, the edges are pretty good. Doing this on my jointer was a challange to say the least. What I ended up doing was, once I got close with the jointer, to but them together with light clamping then find the high spots and hand planing those down. So now I have them all layed out and I put just 2 clamps on them, at the ends, with light pressiure and put a light below. At this point I see nothing coming through so I think they will be nice and tight with 7 clamps, about one each foot. First I'll do two,then add the third.

The loose tenon idea is interesting. I have a beadlock tool that I've been very happy with. I toyed with using it for this application and maybe I'll give it a go. I know the glued joint should hold fine, but I've never worked with anything this big and heavy and it kind of worries me to not have a little something extra to hold it together. The alignment isn't that critical as once I have it all glued up I'm bringing it down to a guy in town that has a giant drum sander and run it through that to get it nice and flat and smooth. For $25, it's worth it.

As for attaching the top I've used these befo

But do you think they will hold up to something this heavy if somebody picks up the table from the top edges? I would use GRK screws to put them on.

I also meant to ask, these type of table top fastners don't offer and lateral binding on the aprons at the ends. I have used pocket screws before and not had seasonal issues. The table will be in Maine. I also considered using lengths of angle iron around the edges. What, given the size and age of this wood, would these methods present as issues?
