The hardwood is more expensive than wood, thinking, 2x6 or 2x8 for the frame. This part of the country is in the Douglas fir may be more common yellow pine.
The catapults are very sophisticated machines, even if it seems easy. Many people begin to build, without really knowing how they work. It is not as complex as the implementation of a satellite into orbit, but there is a much more satisfactory.
Factors into account, particularly want to see what you shoot, and to what extent. The gauge has to withstand at least 80 times the weight of missiles, and the axis must be at least 5 times the counterweight in the event of a failure. Treb an excellent level should rise 50 times the length of the longest side of the arm, not expect a first attempt by more than 30 times.
There are many other factors to consider, such as length of the beam, the angle of the publication of "fingers", as if suddenly c0ck weapons, etc.

OFT response is good, I would say that the business environment of yellow pine and oak and ash for the use of leverage and steel if left on the axle.
Oak and Ash both work. The oak is more common.
For his project, I suggest yellow pine. It is very powerful and much cheaper than oak or ash.
