Part #11 (side of one of the drawers) was not drilled for the cam locks. If it was a simple hole, I'd just drill it, but you must come in from two sides at 90 degrees with two of the holes large for the cam lock and I'm not willing to risk trying this. The drawer wood is very lightweight (like Balsa wood) and some of the boards arrived split, so as I tightened the cams, the splits opened up. One of the frame boards was not drilled with a large enough drill to fit the cam pin into. I opened that one up myself. What's funny is the instructions state "Customer First, Questions, Issues, contact us", but there is no phone number, email address or website. There is no way to contact the manufacuturer to request a replacement for part #11. I ordered two of these chests, so hoping the second one can be fully assembled. So far disappointed.
