Moving Tank birthday cake

FeaturedContest Winner
Super great timing on this cake contest! It's my sons birthday again. Obviously his cake had to be something out of the ordinary. See past cakes -
volcano
helicopter

we were just on vacation at Disney so I didn't want to get too elaborate due to time constraints. My son asked for a tank cake. I'm sure he would have been happy with a cake with a picture of a tank on it or a model tank. But I would not have been happy. First I decided that the turret would rotate. That is pretty easy. I toyed with the idea of having it shoot something (what says happy birthday more than getting shot in the face with whipped cream) That idea got shelved as soon as I imagined the look on my wifes face. To up the difficulty level I decided to make the gun go up and down as the turret rotated.

-Imagine wife smiling-


It is a little difficult to see the gun raising and lowering due to a bad camera angle. Look at the camo icing and the gun shield and you can see what is happening.

Please check out my other instructables and I also have a diy podcast called mechanicalmashup.tv

if you wanted to make it shoot stuff, you could fill some sort of squeeze pump (balloon possibly) with whipped cream, then run a tube up through the gun down under the table, then squeeze it at just the right time.

Why do so many people gripe about stuff like this. It looks cool and that's what counts. Good job.
There's no mention of the motor, could you give us some info?

it was a 6v 3rpm motor and gearbox I bought from allelectronics.com a while back. It was the second of a pair I bought. The first one was used for the pneumatic firing system on my volcano cake last year.

I'd feel bad eating this, its looks so awesome!

That. Is. AWESOME! Beat's my articulated cake out of the water (it used hard moulded icing to create a just-about-working ball bearing so the top could rotate). Thank you, sir- you may have just let me top that! Again, let me say that this is an awesome cake and your kid is lucky to have you!
....half the thing aint even edible
but i dont think it would be easy to cut and eat it because its hard not to make a cut into the cake about 1 inch without hitting metal
dave spencer (author)  MakerBreaker6 years ago
I told my wife to cut it because I didn't want to be the one to wreck it. She had no problems and she did not even see it prior to the cake being placed on it. We ate the entire top at the party less one small piece. The next day my wife took it to her work and everyone was cutting their own pieces. No one complained about hitting metal. every last bite was gone, top and bottom.
but ill stick with the triditional cake....this one looks cool but looks complicated
dave spencer (author)  MakerBreaker6 years ago
You go ahead and stick with uncomplicated stuff. Just know that you may be in the wrong place right now. BTW it took longer to ice the cake with fondant than to design and build the mechanism. If thats what you want to call complicated, you go ahead.
dave spencer (author)  MakerBreaker6 years ago
sorry you are mistaken. Have a look at the pictures attached. That is all the steel in the cake. everything else is cake. Thats got to be 90% cake.

just a question, with all the metal in it, is the actual cake still edible? and if it is, good on ya!
dave spencer (author)  samando6 years ago
Yeah dude, when you look at the cake, there are two levels of pan, one for the turret and one for the base. The only thing you could not bite in the picture is the barrel. It's all stainless steel or tinfoil so its all food-safe. By the way, the cake was delicious!
Genius!
