Air dried and kilne dried in same project question

[Kevin Villas]

I picked up the lumber for my project last week, some cherry. It is a small clock, the case of it is all 5/8th inch thick with a top of 1 1/2 inch thich. The top is 6 1/2 inches x 12 inches long and it calls for it to just be glued to the base of the case which is the 5/8th cherry.

My question is, all of the stock for the 5/8th cherry was kilne dried and the guy at the lumber place told me the 1 1/2 thick lumber was air dried. Will this cause a problem if I just glue it ontop of the kilne dried stock?

Would it be better to screw it from the bottom with holes in the thinner stock big enough it could move a bit if it had to?

Thank you

The drying method doesn't matter one bit...but the MC of the material you are using should be relatively the same throughout for best results. Building to accomodate wood movement is also important. KD and AD material, properly dried will generally reach the same MC after aclimating to their environment over a reasonable period of time.
