In this case a simple recycled brick can become a light or a river rock can become a candle holder!!!
Lots of possibilities from found materials...
Step 1: You will need..
Tool wise you will need a diamond cutter. I used a 10 inch wet saw with a continuous blade since it was only a brick.
Cutting concrete or stone you will need a segmented blade.
RotoZip tools have a dry diamond blade which could work for your material.
A hammer drill with the correct bit will be needed for the lamp column.
Step 2: Core the brick...
Coring the stone or brick in will create a chimney for the heat if using candle or a light path if using a bulb. Drill almost to the base using a depth gauge if possible. I recommend using a smaller than desired size bit first then following with the desired size afterward. The drilling will be faster and less likely to crack.
Step 3: Cut the brick.
Cut the brick in equal segments allowing for a thick base. I cut 5 segments off of the top and left the rest intact.
Step 4: Cut the spacers
One brick segment will yield at least 6 spacer segments.
A 1/2 inch hole will be drilled in the lower brick base if this an electrical lamp...
Step 5: Test the light.
Step 6: Fix the brick.
The cut brick now needs to be reassembled withe spacers that were cut in the previous step.
I used 5 minute epoxy for attachment. Place a spacer using epoxy between of the one inch segments until all 5 are attached...
There will be one set of spacers on the last segment that will not be physically attached to the next set...
