can I trust the 1/2" clearance for drawer slides?
I'm using drawer slides to attach a premade box inside a bookcase I am making. (I want to play w/ my pocket-hole jig! Not Kreg's, unfort--a cheapie.)
Because the bookcase will sit on top of a mini fridge, I am going to make the base come out all the way and have the side supports rest on the base. That way the weight of the unit will be born by the sides; if I nested the base inside,
My box is 17.5" exactly; add the slides, and that's 18.5" Then add .75" for each side of the bookcase. So that would be a base that's 20" wide.
I need things to fit exactly. I'm a little worried I might make things too tight if I don't get my sides lined up perfectly with my base. (I'm having all the lumber cut at the yard, or perhaps by my FIL, because I don't own my own saw.
Should I have my base cut at 20-1/8", to give myself a safety margin? (I can shim if it's a bit too big)
Or should I simply plan on planing or sanding down the box to fit the slides?
