I am building a 13” deep by 43” wide solid walnut media cabinet. I like using veneered tops but have extra boards and have a question.

I have 2 board that would equal 14 or so inches wide for the top. I like the grain match as is. I am worried about a crack down the middle. Should I cut them into narrower boards, say about 4 and glue up alternating grain? or just glue up the two boards alternating grain or same direction??

Thanks

Do you mean a crack where the edges are glued together or is there a crack in one of the boards?
If the boards are jointed properly and clamped so they are flat that joint will be stronger than hell.
If a board has a crack in it I would put a butterfly(s) of contrasting wood in it so it does not progress.
Butterflies, to me, add a lot to pieces in many situations.

?

I have two boards 8”x43 and 6”x43 that I want to make a final 13”x43 top out of. I have never used two pieces for a top where the seam is right down the middle. I am concerned about using 2 pieces vs resawing the boards say into 4 pieces and then arranging them alternating grain.

I would like to keep as is with the 2 boards to keep the grain orientation but don’t want an issue down the line with a crack or other movement issues using the 2 wide boards vs the 4 smaller ones.

Thanks

Spring jointing would prevent end cracks. Four small boards will move also. I assume the boards will not be in a frame. That is where wood movement would cause a problem. It will expand in its width due to humidity and temp. I have made tops with two or three wide boards and kept the grain running in the same direction.
Grains running opposite of each other make for unpleasant planning.
I have seen various opinions on putting the grain patterns on the end with on arch up on one down to prevent warping but I have never been in that camp.
I know it is easy for me to say because it is not my top, but I would glue the wide ones up and I would use cauls to keep them flat.
If anything happens remember I live in Iceland in a remote village.:)

Appreciate the help. What is spring jointing?

I think I have read too much as every book gives you different info. I am going for the 2 as I love the way they match up.

I’ve had to glue up 3 to 4 panel tops and they’re still going strong.

Fridge, that is the point I am unsure about using 2 panels vs 3 or 4.

I went to glue it up and realized the sides are made out of the cut offs of the boards I was using for the top. The seam would line up all across 3 sides. I think now I am going to add a 3rd board to the top just to have an offset in the glue up line vs 1 straight line all across.

I am laughing as if I wanted to line up carcus sides to top up it would have never worked out.

Youtube spring jointing. That is the best way to learn how it is done.
