How to joint 12/4 boards?

Trial and error is all I know. Make each surface as flat as you can, (a straight edge and winding sticks will help here) then bring them together and look for daylight. When you are getting close, work on only one surface at a time in between test fittings. Otherwise you won't know which is causing what.

The joint has so much surface area I don't think you need to get 100% coplanarity. Just get the show edges tight and you should be ok.

>I recall having to do this and struggling with it. As I recall, I just did the best I could flattening and straightening. When the fit was as good as I could get it, I ran a smoother down the center of each board to create a little hollow. The theory was to force the pressure out to the edge to leave a nice looking fit. It seemed to work out okay.

>I needed to joint boards wider than my joynter for my becnchtop, I'll echo what has been suggested. I used my try plane for the bulk of the job, only turning to my joynter for the last few passes. I also sprung my joints a bit.

Good Luck!

>Clamp the two boards in the vise with a scrapboard behind. Then skew the plane as you would do with a scrubplane. The scrapboard helps you avoid tearout. Go over twice in to different diagonals. The surface will not be much pretty, but one or two fine shavings token with the jointer will remedy this.

Thanks for the suggestions!
