Homemade Nest Boxes For Cavity-Nesting Ducks
Attachment Using A Pipe Mount Floor-flange Assembly
Another method for mounting either wood or metal nest boxes is to use a floor flange-pipe assembly. A floor flange is bolted to the bottom piece of the nest box. The bottom piece of the nest box must be sturdy. Four holes are drilled in the center of the bottom piece to match the holes in the pipe flange. The pipe flange is then bolted in place with small bolts and washers of appropriate size. For the metal box, the floor flange should be bolted in place before the components of the nest box are assembled.
Materials needed
- Pipe
- one 7- or 8-foot length of 1 ½-inch inside diameter pipe
- Pipe
- one 2-foot length of 1-inch I.D. pipe which is threaded to screw into the floor flange
- Flange
- one 1-inch floor flange
- Capscrew
- one 3/8-inch x 1-inch N.C.
- Bolts
- four bolts with nuts and washers to attach floor flange
Construction
A 2-foot piece of pipe, threaded at one end, is screwed into the flange (Figure 15). The size of the flange depends upon the pipe available. A satisfactory combination is a 1-inch floor flange into which is screwed a 2-foot length of 1-inch ID pipe. The 1-inch pipe telescopes into a 1 ½-inch ID pipe which is driven into the marsh bottom or ground with a post driver. A 5/16-inch hole is drilled 2 inches from the top end of the 1 ½-inch ID pipe and is threaded with a 3/8-inch N.C. tap and fitted with a 3/8-inch N.C. capscrew. This method of support can be used to place nest boxes either over water or land at many of the same sites previously recommended for wood or metal poles. A simpler method involves screwing the floor flange directly to a threaded pipe driven into the ground.
Figure 15. The pipe flange assembly offers an easy method of attaching nest boxes to supports. This method allows the boxes to be removed for maintenance.
