I wanted to mount my lighthouses up high, without drilling any holes as I would soon be moving this to another room in the house. It was the ~$10 at Home Depot for the parts below
Materials: (for 2 poles)
(Note: I used 1/2″ conduit and as a result had to snip the power plug, but if you use 3/4″ conduit with larger rubber caps, nuts and bolts, you should be able to avoid that.)
2x 1/2″ EMT conduit x 10′
4x 1/2″ EMT conduit strap
2x Wood plate (2 1/2″ x 4 x 1/2″)
2x 5/8″ Rubber leg tips
2x 3/4″ Rubber leg tips
4x 3/8-16 Nut
2x 3/8-16 Bolt
12x 1/2″ wood screws
~10″ 3/32″ Nylon edging (optional)
Picture for one pole:
Tools:
Drill
Drill bit (3/8″)
Hammer
Fish tape
Zip ties
Metal files (round and flat)
Knife/scissors
Build It
Start by cutting the conduit about an inch short of you ceiling height. Then mark a point 3 1/4″ from each end.
Drill a 3/4″ long opening in the conduit at each end, centered on the point you marked, taking care to make sure both holes are in same orientation.
File and smooth the opening, since you’ll be pulling the power cord through.
Attach some tape to the end of the fish tape, feed that into one drilled hole and out the other.
I used some snips to clip off the back side of the power plug to a 45ish* angle, to allow it to fit in the 1/2″ conduit.
Use zip ties to help pull the power cord through the conduit.
Cap the top side with a rubber cap. Then thread two nuts onto the bolt, and put the other rubber boot over the bolt’s head.
Place the top end of the conduit against the wall, and use a hammer to sink the nuts into the conduit.
Attach the wooden plate to the top end of the conduit with the straps. Then attach the lighthouse mount to the wooden plate.
Place the conduit into it’s position, and thread the nut out until its nice and tensioned. I found flexing the conduit would allow me to back the bolt out a little more and create a tighter fit.
