Space Cannon Rebuild

Prior to going to Brick Fest Live in Sacramento, the Space Gun needed some maintenance.  Wasn't quite sure which motor connector was connected to what motor.  Both of the small guns would not turn.  And it appeared that the main gun would not turn.  From this picture it is hard to see, but when the cliff is finished there, the power canisters on the back are going to have to move.  There will not be enough room for all of that to and still maintain the walkway.

 I took it partially apart.  The main gun gun was not sitting on the turntable correctly and kept coming off.  There needs to be a better connection system than what there is now.

On one of the small guns, the horizontal axle had some how pulled back (to the left here) and was no longer engaging the gear.  Thus the axle would turn, but the gear would not.  This caused the mating gear not to turn and in the end the small gun.  You could hear the motor turning, but nothing was happening.

The other small gun had a different issue.  The horizontal axle was in enough to engage the gear, but it went just far enough to cause the vertical axle to be pushed to an angle.  This picture is an exaggeration, but it shows the problem.  The vertical axle was being pushed down by the small gun when it was attached.  Then the vertical axle would slip off the end of the horizontal axle and cause the box to grind.  Sometimes the axle would pass through the 2 x 2 round plate with axle hole and not be connected to this round plate.  That also would cause the small gun not to turn, as this round plate was connected to the vertical axle and then this round plate was connected to the turntable that made the small gun move.

This module is still using an old Brick Controller and needs to change to one of the new ones.  When this is done, some of the gearing can go away since I will be able to PWM the motor for speed control.  At that point there will be some major modifications for the Space Gun.
