Just a note to anyone contemplating the passthrough proof grade materials - shipping has some kinks to work out. If you must order some, you might want to consider ordering many of the same size items so that when they shrink wrap them together, they don’t bend and split the larger pieces along the grain. Not sure why the box was so gigantic on the other axis to allow so much rattle and bounce.
Anyone who lives in a humid state like Florida has likely learned by now how hard it is to deal with the minor warping the PG hardwoods can acquire over a month or two even with a ton of desiccant stored with the PG and air conditioning. I need to tell the unit to run over cuts 2-3 times depending on the level of warp to get through, even then the cut might not make it through the paper in all spots. Without figuring out how to press this passthrough piece flat it probably won’t cut at all. May need to order more powerful magnets than those I have on hand.
