Round Table for School Room #3: Is there a way to joint wide panels on the jointer?

I’m thinking I could fasten a batten on the bottom of the panel with screws then hook my thumb over that to put down pressure on the outfeed. Because of the weight of the panel, I would have to push down pretty hard, but it might work.

I had a similar problem recently. I made a plywood sled 8’ x 12”, placed the board on top of that, then ran the assembly through my planer. Once the one side was true, I removed the sled, turned the board over, and planed the other side.

Sorry, ignore my response – I misunderstood the question.

Put the two half panel against each other and make one or more saw passes between them (with a finer saw if a second time).
see here to see what I mean:

The joint will not necessarily be straight but the two edges will mate perfectly.

Mmmm? Hand plane?

Sylvain,

I have heard of that technique, and find it attractive in general, but I don’t want to risk such an experiment on this project. The joint needs to be very tight. It’s pretty much impossible to bend 17” panels edgewise so clamping pressure can only close the joint by compressing the wood.

I would like to try that on some small unimportant thing first.

Mark Wilson, I’ve got a bunch of handplanes, but my planing skills are not up to this task. Just to keep the edge square to the face would be a challenge beyond me and I always end up with curved edges when I hand plane too.

Thanks to both of you for posting suggestions.

I’m going to do it on the table saw, but I’m interested to see if there’s a way to do it on the jointer.

the edges don’t need to be perfectly perpendicular to the faces as long as they match:

of course if it is too much askew it will tend to slip under clamp pressure while glueing.
So if one has a plane wide enough, the trick is to plane the two edges together.

I don’t know if it is possible but, what about clamping the two half panel together and using your jointer?

Paul, yeah Live and Learn. at this point work it any way you can. An other day another project, rip and joint those boards and dry clamp those edges for the best look. like a cutting board. I hope to see the end product. Remember sawdust and wood glue is a good filler that matches.
