Pi Day Penny Project EZ


The above slideshow is one of those freebie Animoto things.  I played the guitar and took the pics from the blog below. 

The following is a simple and very inexpensive project to make for Pi Day.  For those who don't know, Pi day is on March 14, or 3.14, which is the approximate value of Pi.  I've made a few of these and thought I'd do a quick post about it. 

So the first thing to do is trace the penny.

   This is the traced circle.

I just freehanded a crude Pi symbol.

This is the penny next to the drawing.

As is my usual procedure, I applied rubber cement
to the paper and the metal to be cut.

Then I glued the paper to the penny.

I used an awl to make a starter spot for the 
drill bit to start.

A shot of the drill bit making a hole to 
put the saw blade through.

Here you can see blade fitted through the 
starter hole and me sawing the design out

Another shot of me sawing.

This is what it looks like with the design
cut out and the paper still on.  I also
drilled a hole at the top to fit a jump ring through.

Here is the penny with the paper removed.  Next I 
filed the design to clean up the lines a bit.

Her you can see the jump ring fitted and me soldering
the jump ring shut.  You could avoid soldering by using 
a small split ring if necessary.  

Here's the finished item. It's a pretty quick project, 
if your sawing skills are reasonable. It took longer 
to upload the pictures and write the text than to 
actually do the project.


Would you like to buy one? I know, I know....your probably thinking, "I certainly know his materials cost...".   But let's not forget the fine, silk-like cord and the quality, hand made, jump ring.  I'm thinking 3.14 x 3.14 = 9.8596, let's call it, for a limited period of time, $10.00 even.

A little late for this year, maybe, but I'm more of a glass half full kind of guy and thinking I'm way ahead for next year. 

But mostly, I just wanted to try out my new found skills at installing a google checkout button(working, then not working, then working and now not working again) and Pay Pal(no problems, and they have a phone number), make a slideshow, and play guitar. I've got a little more work above and more work coming.
