LR32 temperature sensitivity?

[bob_barthelow]

I have been having problems with cabinet sides that I am making. Although I have been rigorous about crosscutting to appropriate  mod 32mm length I have found that my lr32/holely rail stop rod gap is at times too narrow to fit the panel. This morning I went out to re-engage the struggle and much to my surprise the set up fit all of my side panels perfectly! The only variable I can ascertain is the temperature of the holey rail & stop rod. Usually I'm working in the afternoon when things are warm. It was cold this morning. Has anyone else experienced this phenomenon?

It could also be the wood
Moisture can swell the panels and it doesn't take much
