Torsion Catapult

We encountered a problem today. We had not taken into account the fact that twisting the torsion bundle will exert crushing forces on our catapult. We must now add crossbars for increased support. Also we added the torsion bundle itself. It is very hard to twist. We must address these new problems promptly.

Today was a super testing day so we could not work on anything.

Today we messed around a little bit with the torsion bundle. It ended up snapping. We will put more effort into creating an effective bundle when we have more time.

We finished installing the arm stop and its supports. Now we will work on installing the actual arm. We have created a few-inch hole on either side of the body that the rope bundle will feed through.

We are finally actually mounting the winch. We are using the lag bolt to screw into the wood with no exit point and the bolts to secure the winch to the rest of the board. Also, we are setting up the angle supports.

Jayce was absent and, while Joe has some experience with this kind of thing, Jayce is a bit better and Joe wanted to make sure that both team members agreed on what should happen. Joe has found suitable bolts.

The bolts needed for mounting the winch are proving to be very elusive. We have found a suitable lag bolt but none of the other bolts have appropriate lengths/diameters.
