Its faster with a table saw and a bandsaw. However, it really doesn't matter what the wood is removed with as long as it is removed in the right places. The DVD shows the table saw method and a little bandsaw work to quicken things up a bit. If someone doesn't have power tools it doesn't matter, it only takes a little longer to build the bow.
As for age, the DVD is great for any beginner as it is easy to follow and makes a great simple first bow. Being under 18, I have to recommend having adult supervision though.
