Step 1: Materials Needed
One Gold dollar coin
One toggle bolt ( 3/16'' x 2'')
Gold spray paint
One brass 3/16 nut
Drill bits ( 7/64 , 3/16)
Hand File Set
Step 2: Drill
First mark the center of the coin and then used the drill set to punch an indentation.
Then Clamp it in the vice with a bit of paper and wood so not too mess up the finish.
I started with a 7/64'' hole then went through with the 1/16'' drill bit to give me my final hole size.
Finally remove any burrs with a file if necessary.
Step 3: Grind
You can do this however you want, but I am not good at eyeing things so I used angles to help me out.
The first thing I did was to file the head down till it is flat and no grove can be seen.
Then I made the head square.
After that I filed it down a bit thinner and made it into an octagon.
Then I rounded it off and made it even thinner. Now it sits almost perfectly on the coin.
The final tweaks can be made by setting it on the coin and identifying the high points.
Step 4: Paint It Gold
Let it dry!
Step 5: ATTACH
Step 6: Application
Your want to spin the wings down to the bottom of the threads and then push it into the grate or manhole cover until the wings pop out on the other side. Now you must tighten it. To do this you must pull up while turing to get the wings to catch on the under side of the grate. Then once it's finger tight give it one last lil bit of torque with a pair of pliers. But be careful. If you tighten it too much you will pull the thin head of the bolt through the coin. Remember you just want to make it more than finger tight. Because im assuming that no one will be carrying around a pair of pliers to remove it. You never Know though. =P
Step 7: Location
This would be fun on any street, but would be especially nice in a place where there is allot of foot traffic. I chose to put it out side my house because I have a view of it from my window.
A better location would be out sides ones office where they have a view of a busy street.
Remember any grate or manhole cover works well. ( The hole should be from 1/2'' to 1 1/2'' in diameter)
