We are a cabinet and counter shop.
We had a walnut desk top made since we do not make custom woodwork.
They glued 1 x 6 walnut together then they glue or screw a 3/4" MDF on the underside will stacking the perimeter to appear 1.5" top.
It was brought to the office set in place with the heat of the room was very hot.
After a few weeks the center plank crack about 1/8" and traveled down the plank 24".
Should of the walnut been glue or screw to the substrate?
Thank you

You will get a lot more help if you post this question somewhere besides the dust collection, safety, and plant operation section. That top breaks all rules of solid wood construction. Wood expands and contracts, MDF does not. Cracks and warpage are certain when built like they did. Definitely no glue, but screws could be used if the holes are slotted and allow enough movement of the solid wood. The banding around the top will also cause trouble since the grain is opposite the solid wood top on the ends. I suggest you get your money back and find a cabinetmaker that knows what he is doing.

The people you hired to make the top know little about working wood. Get your money back and give them the top.
Rich's explanation is valid.
Solid wood moves: it must be allowed to move or there will be problems. There are several ways to make the top successfully, but one should know what they are doing before doing it for hire.

If they want a 1.5" thick top it is either solid with end grain showing or use veneered MDF core and put a solid edge on it for thickness.

It's too bad that people with no knowledge of their materials make things that go totally against good practice. Get your $ back. They have no clue. Rich is correct.

Same conclusion
