Method of securing each section of the frame (nylon cable ties through 1/4 inch drilled holes)
(recommended if you plan on using the frame in the field or underwater)
You will need to file off the sharp edges of the ties after you have snipped them to length (a bit of tape also helps)
You could use 1/4 nylon nuts and bolts if you wish
