Adjustable circle cutter

how to use an adjustable hole saw to make the perfect Avian Aqua Miser holder

An alternative to hanging the
Avian Aqua
Miser
is the above wood mounting.




I don’t think chickens care
much if it’s hanging or shelf mounted, but I think it’s a tiny bit
easier to access when you don’t have to find the hook in point.




The tool needed to make such
a precise big hole is called an adjustable circle cutter.




We used a drill press to make
ours, but I imagine it could be done with just a regular drill.




Set the depth to drill a
little past half way. Once the pilot bit makes a hole in the other side
flip the piece over and start the circle on the opposite side. The
circle size should be set on 2 and 3/16th’s which is the radius of the
hole.




I chose an 8 inch wide 1 inch
thick appearance board that can be found at most lumber stores. Add
some small shelf brackets and it’s ready to install. You might want to
add a layer of paint if it’s going to be exposed to the elements.
