This is probably a silly question but here goes anyway. I have a 1950's sideboard with drawers that have a center slide (with ballbearings) attached to the cabinet. It has been in my basement for a while and I can't get two of the drawers back in. I recall having this same problem some years ago when I had to remove a drawer to retrieve something that was stuck but my Dad was around to put it back in for me. I thought I was paying attention, but apparently not intently enough. Any help would truly be appreciated.
