Introduction: Broken Gothic Arches With Electric Candelabras
Welcome to my first instructable! This is a project I was paid to do for a Halloween Party for a bar in Nashville in 2005. I created these broken gothic arches with candelabras out of styrofoam and pvc. This is the only project that I have actually documented, so I thought it would make for a decent first go at creating an 'able. I hope you enjoy it, and can actually have some fun making these neat props. Please feel free to contact me with any questions.
Step 1:
I was able to get quite a bit of these styrofoam sheets from a friend who worked for a local contractor. They were happy to get rid of these old concrete forms. However, if I were to do this again, I would probably use the pink insulation sheets available from one of the bog box home stores. Cutting styrofoam is a huge mess that leaves lots of polystyrene beads EVERYWHERE!
Step 2:
The polystyrene sheets were long enough, and of the right width to get a couple of the shapes I would need to glue together to make the appropriate thickness for the broken arches. I attempted to use one of those heated wire foam cutters, but that took a long time, and stunk up my apartment, so I switched to a hacksaw blade. I traced the shape out with a sharpie marker, cut one, and used it for the template for the others.
Step 3:
This was the original cut shape. I measured them out to be a bit too short initially, since I wanted to have enough room to carve the broken edge, so I changed it to be a little longer
Step 4:
This is the "new" shape that appears in this photo to be glued together, but it is not. I was testing to see how much styrofoam I would lose by making the shapes longer. If you plan out your templates to make the best use out of your styro, you can make a lot more pieces.
Step 5:
These are the styrofoam pieces, glued together. I used four foam pieces, adhered with Gorilla glue. (Note: Gorrila glue seems to expand as it cures, and I had these foam blocks sitting on my carpet. I ended up gluing a few of them to my dining room floor... yeah.) I made 16 of these broken arches. The bar had a sixteen columns throughout it's floorplan, eight of them were in a double row of four on either side of the bar. This made for a really cool look! (see first pic)
Step 6:
Next, I carved the "broken" edges and the stone joints with a hacksaw, and coated the styrofoam with a layer of plain tile grout. This is available in 5 gallon buckets at the home store. If I had been able, I would have colored the tile beforehand by adding the latex paint to the grout.
Step 7:
I painted the broken arches with a grey latex paint.
Step 8:
Then with some black paint, I dry-brushed the details of the joints between the stone and cracks and the like.
Step 9:
This step was kind of a huge pain, because I didn't really think of how much cutting of pvc I would be doing. I used a hacksaw blade and since I didn't have a real workshop, and a way to hold them steady. It was a hassle. When I was down to my last few pieces, a friend of mine came over and said, "Why didn't you use a pvc pipe cutter?" That would have saved me a great deal of time and trouble.
I started by using various lengths of pvc for the candles, with two 90 degree bend joints and one 4 way piece. I used hot glue to simulate the melting wax and painted them with a pale yellow latex paint.
The lighting was pretty simple. I am not an electrician, but it seemed pretty basic. I used flickering candle bulbs, and light bulb sockets and standard lamp wiring, with a little switch that had a fuse inside it.
Step 10:
I had to make 16 of these, and as I mentioned it was a pain. Please save yourself the time and trouble and use a pvc pipe cutter. I used schedule 40 pvc, but you can use the lighter stuff if you like.
Step 11:
The finished candelabra, with a piece of mounting "stone" Note the lamp on the floor behind it that I used so I could wire the candles properly, and not burn my place, or the bar to the ground.
Step 12:
And... again... the finished product. Decorated with those cheapy cobwebs that you stretch over stuff. I used bailing wire to attach the arches to the columns. Thanks for taking a look!

awesome, a shame the pics are so small = ( I've found that the best way to cut styrofoam is with a serrated knife and use straight up and down cuts, this means cutting on an edge of a table and can be tricky with thinner pieces of material, it's not totally beadless but its a lot less than any other method except a hotwire. Thank you for sharing and welcome to the world of ible posters !

Hey Thanks!! Yeah, Sorry about the small pic size... I had to take the pics off of another site I had uploaded them too, after the originals were lost in a hard drive crash, and they had to be reduced in size for that site.
