It is a simple board, but the boy loves it. I mean c'mon, give them a box and there are activities for days! I'll give you a quick rundown on the build, but you make the final as to how complex or simple you want to go.
3/4 inch high grade plyboard (Cabinet grade)
1/4 inch panel board
Drill bit (I used 1 inch hole saw bit)
1. Cut board to size to fit the top of the toy box. Then round the edges with your jigsaw.
2. For ease of flipping and holding, I drilled and jigsawed hand openings at each end. First I drilled two holes about 6 inches apart using my hole bit. Then using the jigsaw, I cut the remainder of the hole for the handle.
3. Using a straight bit for my router, I first cut the deeper part of the lake. Take your time and make sure you go against the rotation of your router. Then shorten your bit and finish the rest of your lake.
4. I then cut a few a few shapes to make hills. Start with the larger base and then start adding to the nest levels. You can get crazy or go simple, your choice.
5. Glue everything in place with wood glue.
6. One side will was requested to be white. I left this side to be flat so it could also be a Lego work table.
7. I used spray paint, but any paint will work. I also taped the edges to give that wood look to the edges. It was a nice pop.
8. I went with a normal green for the landscape, and two blues for the water. I went simple, but you could really get detailed here. I had to talk myself out of it. I really love to make more work for myself.
Overall, it was a fairly quick project that has already gotten tons of use. There has been many Lego battles and projects on the board. Though for some reason, I really want to drill a small hole and make a mini-golf course.
