Without knowing anything about wood working, I jumped into a "weekend project" in the middle of the book. The pirate treasure chest/toy box looked easy enough, so I copied the shopping list and went to Home Depot. $70 later I had the materials. After 9 hours of work, I had a finished toy box that looks very much like the one in the pics. It's a quality piece, built by an idiot. (attaching pic above)
Handy Dad has tons of helpful pics, and the directions are thorough. The projects vary in complexity, but everyone should be able to do at least half of them. Material costs will vary, but a cost estimate on each project would have been nice. Still, great book.
Edit: I built the skateboard project (pic above), also a "weekend project." It looks great and rides even better. It only took 5 hours, some of which was selecting parts. There's a ton of variety in skateboard stuff, so I talked to the people at a local Zumiez shop. I selected good quality beginner stuff, and spent around $170 after tax including the wood. Keep in mind, a nice longboard starts at $200. Just semi-pro trucks start $100 each. This could be a $600 skateboard, or I priced it as low as $60 if you use all cheap stuff. I guess this is why there are no price estimates; costs will vary depending on the builder. Also, the author likes Ipe wood for some of these projects, but my local WoodCraft didn't have any. They suggested Brazilian Cherry could do the same thing. Finally, I tried to use one smaller size drill bit than what the instructions said. I figured the hardware wouldn't be loose in the deck that way, but then they wouldn't even go in the holes. Turns out the directions are spot on.
