reframe under kitchen sink

So under the sink it was totally collapsing.  All there was was the thin and very old laminate to hold up whatever was in there.  Worse yet, I discovered once I start to demo that it was one continous piece that went to both sides and the adjacent cabinets.  So you had two cabinets plus under the sink, all unsupported and held by 'wood' that was about 3mm thick.

So I smashed it all out under the sink and then used a sawzall to cut it as flush as possible.  I cut three sets of 2x6 and screwed them together.  I banged them half way underneath on both sides, so you had one 2x6 under the adjacent cabinet, and the other exposed under the sink to mount my plywood to.  I then added cross supports and used the Kreg (really my only option here) to hold it all together.

Later I cut my plywood and used a holesaw to cut the holes for the hot/cold water supply pipes.  Then I used the sawzall again to cut straight down through the holes so I had two halves.  I used nails instead of screws to attach the plywood to the supports.  I even built a small trap door in the front right 'compartment' with two tiny hinges so secret things can be stored there.
