1. Cut your long PVC pipe to your desired lengths. I used a chop saw (Pic) but if you don't have that then you can use a hacksaw. I went in 2 inch increments (12", 10", 8"...etc.). I also tried to cut them a little taller or shorter than each one of the those increments so each candle looked to be a unique size.
2. Place the pipes upright on a hard surface. Make sure you cover the surface with some type of material since the foam insulation will come in contact with it. I just put down some painter's paper on my garage floor and set the pipe on top of that.
3. Fill the pipes with Great Stuff Insulation Foam. I usually filled mine about 1/2" from the top since it expands.
4. Let the foam dry completely. I filled mine up at night and then worked on them the next day.
5. Cut off the foam so it is even with the pipe. I came back with chop saw to trim it off or I found you can just slice it off with a hacksaw as well.
6. Use you forstner bit to trim down the foam inside the pipe to the desired height you want the tealight to sit. I found that putting the drill in high speed mode rather than high torque works best. Drill slowly so the bit cleanly slices away the foam. If you go to fast the bit just rips out chunks.
7. Once you have the pipes drilled out it's time to apply the hot glue. I found that using a high temp hot glue gun works the best. Since the gun is high temp the glue becomes very runny and creates nice drips. Just work around the pipe and going in multiple layers seems to give a nice effect. Another thing I found out through the whole process is try to make a nice long drip right over the printing on the pipe. When you paint it it will help in covering up the printing.
8. After the glue is dry you are ready for paint. If the printing on the pipe is showing you can try to remove it by sanding it off or using nail polish remover to take it off. Spray the candles in nice smooth strokes making sure you get all the nooks and crannies around the drips. It took me 2-3 coats to get the printing on the pipe to not show through.
