A for Ambiguous!

After making a concrete light bulb, ideas for small scale concrete projects were constantly popping into my head. So when I was invited to join this project, I knew what I'd be doing. For the mold, I printed out a large letter "A" and formed it, like bumpus, out of cardboard, with hot glue to seal the edges. For the inner triangle, I just did it free hand with a long strip...much easier than cutting three thin strips. I also made sure to make the mold on top of a large piece of card board, so that I could easily transport it, and vibrate the bubbles out of the concrete.

Time to pour! Mix up your concrete and pour into the mold. Once you've poured it all in, fill in all the cracks and smooth it out with the tool (shown in fourth photo). Then shake the cardboard base, to get as many air bubbles out as possible. Now we play the waiting game!

I've read that spraying concrete with water as it sets will make it stronger...I figured it couldn't hurt, so I sprayed it a few times a day, for about two days until it seemed fully hardened. After removing it from the mold, I waited another day or two, giving it maximum surface area exposure (stood up) before working on it any more.

Next, I pulled out a metal file and leveled out the feet until it stood sturdy, and got rid of a few imperfections. It's decoration time!

First, I sketched out a picture of the Robot onto the bottom right corner, and then used my Dremel to carve his likeness. This didn't turn out so well, as you could barely see him. A Sharpie came next, I used it to fill in the grooves. Voila! You can spot him from a mile away! After It was truly an Instructables A, I used the same method on the back to carve and fill in in my name. I also wrote on another drawing/message.

At this point, the A was a bit wobbly, so I found an L bracket and used mighty putty to attach it to the back. Lastly, I added some felt to the bottom (I don't want it to scratch anything in it's new home!), and with that, my letter was complete!
