Which one do you like better?1st thing to do is make a jig...
*Take your paper template and trace its shape onto the wood that you will use for your jig. I used 1/2" MDF but you can use 1/4"
MDF, Masonite or plywood.
*Use your jigsaw now to cut out that shape from the MDF. Once cut out, I took a belt sander and cleaned up and smoothed all the edges around the jig. This will be your main jig now. This jig is what the router bit follows to cut out your perfect ellipse.
*Select your wood to make your table from. I chose pre-finished birch.
*Put the wood template onto the wood you've selected and clamp it down.
*Route around the jig with the router bit riding against the jig. I used a 1" pattern bit with a ball bearing. This is what rides against the edges that I smoothed out earlier on the jig.
*Once the main shape was routed out, I switched to a 22.5 router bit and routed around the edges once again. This gives me the 22.5 bevel on the edges just like the Eames table has. (actually its a 20 bevel - but who can tell;~)
*Now the table top is ready for your design.
*I masked off the edges and painted the top white. I left the edges exposed to show the different plywood layers similar to the
Herman Miller/Eames surfboard table.
*Lay out the location of the stripes with painters tape.
*Now start adding your pennies!
*I used white glue and Q-Tips. Type of glue doesn't really matter because the whole table will be getting covered with epoxy resin later.
*When you are done, remove the painters tape and now you can lay out your copper/chrome maple leaf decals or whichever
design you prefer.
I made it at TechShop
TechShop is awesome - if there's one in your area, you should check it out.
Aluminium Sulfate, Shortly known as Alum, when added to raw water reacts with the bicarbonate alkalinities present in water and forms a gelatinous precipitate. This floc attracts other fine particles and suspended material in raw water, and settles down at the bottom of the container. The water over this sediment is almost clean other than some fine particles dissolved in it.
Alum is in a crystallized form which you can powder and store in a clean glass container.
Bleaching Powder Solution
Bleaching powder or chlorinated lime is used to disinfect the water from bacteria. The chlorine present in the bleaching powder solution kills almost 90% of the bacteria present in water.
Bleaching powder also known as Calcium hypochlorite is in a powdered form. Add one or two teaspoons of the powder in a glass bottle, add water and mix well. Use a metal cap for the container as it may corrode plastic cap.
Both Alum and Bleaching powder are commonly available in most of the grocery stores.
