Hi, all, I have a 1940s Hoosier-style base kitchen cabinet on rollers that I'm restoring. I've rebuilt all the "guts," including the drawers and face frame. The original wood cabinet was built with tenons and channels/grooves, so all the parts fit together like a giant jigsaw puzzle. No problem, but I decided to replace the undermount wooden drawer tracks with Accuride center mount slides. So here's the question: I am using the original fronts on the new drawers. The replacement drawers are boxes with false fronts. The instructions for the Accurides say to align the front of the slides with the front of the drawer cross rails. But since my drawer boxes — they're 1/2" birch plywood — have a false front, should I scab on a 1/2" strip of plywood directly behind the cross rails to account for the 1/2" box front, then mount the slides a 1/2" back from the front of the cross rail? Or is there any reason to do that? Sure hope this makes sense!
