i've always built cabinets w/a rail between each drawer. I've seen some posts where folks don't do that...rather there's just 2 stiles and 2 railes and all the drawers sit just sit between the rails and you just mount the drawer faces so that there is a mimimum gap between them once all the drawer boxes are hung.
These are going to be shop cabinets so i'm worried a little about dust getting into the drawer boxes...so here's my questions...
1) does this design have an issue w/sawdust getting into them?
2) what's a good gap between drawer faces?
