I'm still in the process of building the base cabinets for my shop, along pretty much the entire 30' length of one wall. It's been an ongoing project that I have been doing in my spare time, mostly on weekends, for what seems to be forever now. I am new to cabinet construction, so its taking a lot of extra time.

The carcasses are complete, all of the drawers are built and installed sans the fronts, and I have almost half of the doors made and installed. The doors are shaker style, with plywood panels, the rails and stiles are made of Poplar. My rail and stile bit set set leaves a square corner on the inside corners. On the doors that I have built so far, I've glued them up and then slightly rounded these corners over by hand with sandpaper, but man is it getting tedious! Especially along the rails, where it is easy to slip and sand across the grain of the plywood. Any advice on speeding things up, or maybe changing my process?

Thanx! Matt
