on the floor outlines in the JB Corn Books it shows the 60 degree angle walls i was wondering how do you connect the panels together when using the 60 degree angle on turn or corners

The short answer is hurricane ties...

and cross brassing across the top of walls.

The simpson strong tie number is A-21, available at Home Depot or Lowes but. gettting pricy. The original Castle Dragon had hand made straps made from sheetmetal, 16 to 18 ga. galvinized and later these ties became available.

One is put on the top face at slightly above head height where side lumber is with screws, another is installed at about ankle height.

If neccessary the wall is rotated or hinged into place and then another 2 clips are installed on the opposite face in similar locations. You end up with 4 hurricane ties per joint. and it forms an inmovable link to some degree even before the bracing is installed.

The A-21's are getting expensive like 84 cents each so I have found I like A-15's at 30 cents each but they need to be bent. Bigger, basically flat sheet with lots of holes bt the far side of a triangular grid wall gap is pretty wide and this spans just right.

An A-21 comes with a 90 degree bend and 4 holes for screws. You usually bend it open a bit more to be the same angle as you need.

There is top bracing lumber as mentioned.

Hmmm, dimensions of the grid on the floor. Hmmm, next question will be.
