I have some long wide plain sawn boards that have cupped.

I plan to split the board along the maximum line of the cup.

Then I should have much flatter two pieces that I can join back together.

But the max line where the board is cupped the worse run in a diagonal sort of.

So I drew the line and will spilt on my BS when I get the new tires installed.

Then I will joint that BS edge and then see where we are.

Hopefully after rejoining I can glue them back together along that jointed line and will that result is a flater board?

Sounds like a good plan.

That will (should) work well. I've done that a few times.

Thanks all and my band saw tires are due this afternoon.

Pictures

The bottom board high spot is 6 -5/8 one end and 6-3/8 from the opposite side on the opposite end.

Top board is closer but still high spot on ends is offset by 2"

Total wrap in the board 1/2" bottom and 3/8" top.  

If these were 2x boards I may just joint and TP them.

But as they  are 1x boards I need to be conscience but my Jointer is only 8"  Where my TP is 15"

So even when flat I split them then joint the back together.
