Well, this is my first instructables because i never bothered to upload anything else i ever made. I made this is my wood shop class so i can give it my mom for her birthday. My current other projects are: T95 American Super Heavy Tank Wood Model, Wooden Headphones, and the best portable spearks anyone can ever get. I''ll actually try to make those instructables step by step, but this one is just pictures. However, i do have full, extensive instructions!!
1) Choose 3 differnt types of wood, distingly different colors (I used Maple (white), Poplar (Green), and Mahogany... i think (Red/Brown).
2) cut planks that are about 3" wide and whatever length you want. (remembr, the more wood, the taller the spiral can be!)
3) Plane down each plank to 1/2"
4) Cut planks in halfish so you get 2 planks of each wood type
5) Glue planks together in alternating wood type, so you get this layer of changing color and awesomeness. Total 6 layers, 2 of each
6) After gluing is finally finished, use a bandsaw to cut the block into a near perfect rectangular prism that is around 2.5" x 2.5" x however long.
7) Now, you should have a long striped block. Cut this into around 3 or 4 pieces depending on how long your block is.
8) Find the center of each block, and use a 1/4" drill bit to drill a hole down the middle of each block.
9) Now, proceed to any machine, and "slice" the blocks into tiles around 3/8" thick (you can do any thick ness but i found 3/8" attractive). You should be left with a bunch of 2.5" x 2.5" x 3/8" wooden tiles that are striped and and have a 1/4" hole down the middle.
OPTIONAL) I used a router table to round out the edges, but it is unncecessary. I just though round edges would be cleaner, AND safer.
10) Sand the top/bottoms of each tile with 110 grit sandpaper, lightly so it doesnt cut too much away at the wood, but only so the tiles will glue well to one another. The use 220 grit sandpaper to sand out the edges, so it is smooth (want it nice cause it the visible part)
11) Get a 3/16" wooden dowel, and but it through one of the tiles. Try to get a surface where there is a hole in it, so the dowel can go throught the bottom, but not fall all the way through
12) apply wood glue to the top of tile 1, and put the the second tile through the dowel and unto the top of tile 1. Slightly twist the 2nd tile so it somewehre around 5~10 degrees twisted from tile 1. Allow the glue to set for about 1 minute. (remeber, use only small amount of glue, and apply it close to the center since it spread when stacked and helps to keep the dowel in place also)
13) Repeat step 12 with ALL your tiles so you have a gradual twist, allowing each level to set so it doesnt shift when adding the next layer. (REMEMBER NOT TO PUT GLUE ON THE TOP TILE!!!!)
14) After all layers are on, clip off the excess dowel at the tp and bottom. Get a giant metal vice to keep it clamped, or if you dont have the luxury of a vice, place books several books on top of it and leave it overnight to cure and harden.
15) After the glue is dried, proceed to sanding. (the sides shouldn't need any sanding if you used the right amount of glue, and if not, the glue probably leaked out and you need to HAND sand it away). Sand the very top and bottom of youre spiral block so the dowel is flush with the tile.
16) Now get a 2" fostner bit and drill about 3/4~1' from the top of your block, so the candle can go in there. Try to keep the bit as centered as you can.
17) Hand sande the inside of the hole your drilled.
18) All we have to do now is finish it: I used a clear gloss polyurethane coating to get that nice shiny gloss. This is a must, since it portects, shines, and intensifies the contrast of the colors between the different wood types.
19) after about 3 coats, making sure every nook and cranny is coated, let it dry fully (1 day after last coat)
20) Now put your candle in there and light away!!
