I've got 24" metal drawer slides attached to a case made of solid
quarter sawn cherry. Of course, the slides go across the grain. I'm
wondering if I need to be concerned about the case cracking due to
wood movement. The drawer slides (Accuride) have little slots about
1/4" long, but my wood movement calculations suggest that I ought to
plan for 3/4" of wood movement.
Is this OK? Anybody ever seen a case that was cracked by drawer
Oh good lord no, 3/4" movement would be if you submerged it in water and
left it there. I seriously doubt you would ever see more than 1/8" movement
over 24" under normal circumstances. Put the screws in the slotted holes.
If you still have doubts, elongate the slotted holes.
I have never had that problem having installed hundreds of slides.

According to the shrinkulator
(http://www.woodbin.com/calcs/shrinkulator.htm ), assuming a range of 25%
to 60% relative humidity, this will result in moisture content range of
5.4 to 11. Quartersawn means that you want to look at the radial
change, which is 0.18" over 24".
I think you're probably fine.
The shrinkulator is handy. I was doing calculations based on
equations from Hoadley's book. How did I get 3/4"? Well, two
things. I was originally calculating for flat sawn maple and I think
I forgot to switch the numbers for quarter sawn. And I assumed a
broader moisture range, like 75% - 10%.
I guess I won't worry about it. Now if I can just get the drawer
slides adjusted so that the drawers are lined up....
