Meeting 5: Getting the release working

May 18, 2013
Step 17:
we cut three more pieces of wood to use as a release point. One of them will be attached against both of the stands of the fulcrum. It will be placed so that the arm is at a 45 degree angle.
Step 18:
After we marked where it's going to be placed, we drilled holes where the brackets are going to be placed, then screwed them in.
Step 19:
On the large dowel, we marked where the middle of it was in relation to where the ends were. Then we placed the mid-arm in the center and held it there using hairbands and rubber bands placed on the outside of the mid-arm and the edges.
Step 20:
After securing the mid-arm, we pushed the arm down to mark where the middle was on the wood that would be used as a release.
Step 21:
On both sides of the mid point of the wood, we marked where the other two pieces that would hold the arm would go, drilled where the brackets would go, and screwed them in.
Step 22:
After finding and marking where the three intersected, we drilled somewhat large holes where the release would go.

After that, the catapult was finished for the day.
