The second door is up!  Why all the holes?  The 2 on the right are for access 2 tracks, which will be on the other side of the door, but behind the styrene curving on the other side.  The larger hole, is for the F&M branch to come through.  The track is curving as it goes through the hole, that's why it is so big.  This view is from the Kingfield side of the backdrop.

The goal of the next session was to get all of the doors (which support the backdrop) up.  However, Paul and Don were not able to attend, so the limited crew was only able to get one door up.  Tom and Jim cut the holes in the door, while Phil cut the gusset plates used to hold up the backdrop.  The gusset plates were a challenge, as they had to hold the door 6" from the wall (tracks go between the door and wall) and at a 61 degree angle.   Adding to the challenge the gusset plates could not interfere with the tracks and backdrop.  It took a while, but Phil came through with a sound design and craftsmanship.  The door is in place!  Besides getting the 48" door section up, we spliced an 80" door to a 23" section, to make a 103" backdrop core.

This view shows the Phillips/Madrid side of the door.  The two gussets which Phil made are seen connecting the door at top and bottom.  Two tracks (from Strong) will come around the left side of the door (over the lower gusset).   The inside track is the F&M branch, it climbs a grade and goes through the larger hole, to get to Kingfield.  The other track is the continuous run which goes to Phillips.
