Drawer pieces are now thicknessed and Blum slides arrived but now I'm a little worried about how to assemble the drawer with my design. 
I want half-blind dovetails set into the visible face panel; not a false drawer front. And it should fit flush inside the case with just a very small gap around. But now that I'm looking at these slides, I feel like it's going to need a much larger gap at the bottom than I expected.
I've never done this before and I can't afford any more time or money messing up the drawer so, I'm constructing a practice box and drawer (sigh). I probably just need to leave space below the first dovetail but how much space? Soon I'll know.
