So far we installed four wall cabinets. Boy - was that much harder than we expected! The corner took us a while to get leveled, but wasn't too bad, especially considering it was the first one. Attaching the two small 12" cabinets next to it - that was pretty much horrible! First of all, they're so narrow, you can't fit the drill in to screw it to the face frame of the corner cabinet. This means we had to HAND-DRILL the holes 3 times each: once with the small drill bit that goes all the way, then with 2 subsequently larger drill bits that only go through the first cabinet's face frame. Hand-drilling is not easy! Second, the corner cabinet's diagonal face frame made it very difficult to align the cabinets to each other, and also made it impossible to use the cabinet claws (see picture below), so we had to use regular C-clamps. Because of the hardships of alignment and leveling, the toggle bolts were hard to align as well (with toggle bolts, the anchor needs to go inside the wall before the cabinet is up, and the screw then should go through the cabinet and into the anchor). And yes, the 12" cabinet to the right had to be attached to the wall with toggle bolts, because it completely misses the studs.
By comparison, the last cabinet we attached so far, the one over the sink, was very easy. Although we had to use toggle bolts for it too, because there's only one stud behind it, it aligned perfectly almost without adjustments. It was also finally possible to use the cabinet claws, and to drill with a machine. Much better!
We work at night - hence the glare...
Even though we could use the cabinet claws as clamps and guides to drilling, we nonetheless could not use them for screwing through, because our screws' heads are too big. Figures! Still, it wasn't too bad. Now we'll need to see if the 36" cabinet can fit in the remaining space!
