Yes, I mean a worm made of metal. Perhaps something completley new, perhaps not. Still, its kind of special. Here are its various stages:
33137
The wax up process is completed, using an electric waxing unit, as well as several non heated carvers. The finished wax up is now sprued and attached to a rubber base to create a mold.(this is a one shot mold, so no I will not be making more) Chill vents are attached to various locations to help the thicker parts cool. At this point, if something goes wrong, it would have to be started from scratch again. (~4hrs)
33138
Thankfully the metal casting went fantastic, and it turned out great. (The metal was forced into the mold using centrifugal force, after being heated to 1600 degrees Celsius) The next step is to remove the sprue and the chill vents. (~2hrs)
33139
The sprue and chill vents are removed using the equivalent of a hand dremel and several cutting discs. It is now ready to be polished. (~30min)
33140
The little guy is all polished up and ready for battle, there is some minor pitting present, but hardly noticeable at life size. (~30min)
33141
I suppose you were wondering what life size is? Well now you know. Now if you'll excuse me, I have a Monopoly game to dominate with my new piece!
Is it sad that my iPhone takes better pictures than my digital camera?

Hehehehe... will you continue doing this? It's awesome! :D

Really good idea, I admire your precision working on a so small figurine ! The iron and the thimble of your Monopoly game have to watch out !

I expected a poorly MSPainted metalhead worm or a poorly MSPainted worm made out of metal but this is actually pretty well made. Good job.

I feel like I have a duty to make a joke about this.

Then joke away my friend. Also I'm glad you guys like it, since, like many pieces of art, it's better in person.

Hey, that's neat! Just one thing though.

*Centripetal force.

I believe either term (centrifugal or centripetal) works. The metal has a centrifugal force relative to the mould, but the mould has a centripetal force relative to the metal.

Haha, that was the very first thing I thought of when I saw it all polished and chromey. That's the coolest. Nice work. Clay ✔

Plasma is correct. If I find more time to do something like this again, I'm thinking of remaking my old Sniper Worm into metal. Do you guys have any suggestions on improvements/ideas on what to do if I do it again?

All I have to say is style related, like the top of the head could be more round.

Every physics teacher I've ever had told me there is no such thing as centrifugal force.

You use a centrifuge to create centripetal force.

Well are you just upset about the fact I didn't include the word "reactive," because I assure you, its quite real: Reactive Centrifugal Force (http://en.wikipedia.org/wiki/Reactive_centrifugal_force)

You use a centrifuge to create centripetal force.
It's a fictitious force (http://en.wikipedia.org/wiki/Fictitious_force), a force that only appears from a non-stationary relation (in this case, the spinning mould), but it still counts as a force and wrecks up certain calculations if you ignore it.

Well are you just upset about the fact I didn't include the word "reactive," because I assure you, its quite real: Reactive Centrifugal Force (http://en.wikipedia.org/wiki/Reactive_centrifugal_force)
Reactive Centrifugal Force is something else entirely. That's the force that the spinning thing experiences due to an equal-opposite reaction.
