Megalodon resculpt over museum cast

Recommended Posts

Ok, trying this again as I mistakenly hijacked @BellamyBlake excellent thread by bad tab shuffling! Sorry!

 

anyway....

 

heres is what I started with. Managed to get five coats of white spray paint stripped off. As you can see this is a pretty poor cast.

Next, root sculpt and pit and void correction:

Next, bourlette and enamel work, plus a bit more root:

More details and another layer. Yes it’s thick and exaggerated, but this is to ensure there’s extra Apoxy to sand and polish away and still have enough to do physical weathering!

Now wait at least six hours to do lingual side, then a few more to do initial sanding. Then physical weathering, prime and paint. Was given two weeks to do this project, bet I can finish it in four or five more days! The warm temps are helping cure times significantly.

So thanks to a sunny day I was able to save a few hours cureing time and get the pre-sanding primer and reference detail washes done. This darkens the incised areas and highlights the high points. I used one two very light coats of gray universal bonding primer. About an hour later I spayed on a thick coat of black primer, then immediately wiped it down. I do this to ensure I don’t accidentally sand off details. Now however a few hours is needed for the next step, as one never wants to overwork epoxies with solvent based primers.

A bit of wetsanding and a black wash or two later and it is starting to look like a tooth. You can see a few low spots that will require a bit more putty and sanding, but I think a full paint is much sooner than expected.

Well, as you have probably noticed there are no serrations. Last night I got some more weathering and buffing and painting done. I just now figured out how to make the serratia museum accurate, but I will have to make the proper tool to do it first, so, later today I will post details on that. PVC pipe and enameled inductor wire from my HAM radio days should do the trick!

Phase1 of the serration sculpt. Again overly thick and exaggerated but gotta leave extra to sand away and bring into scale. Used a few feet of induction wire wrapped over a few inches of 1 inc PVC pipe with one half sawed off to make a comb to get the spacing on the serrations correct. It’s cool here today so curing times are longer, but this makes the Apoxy easier to work with.

And here we are. Final paint and weathering complete. Nothing left to do but clear coat and placement on a custom base. I’ll post all that when complete.

It does look quite realistic! I'm not a big fan of replicas and reproductions, but that is one you can certainly be proud to display! Especially since it's your own craftsmanship!:meg:

I prefer the real deal too, but I know better than to let students handle the real thing. had an oreodont skull "disappear" that way...

These are strictly for education.

The base models are all museum casts that were donated to us here at the Uni.

I hadn't realised this was for education. Makes sense, sorry to hear about the oreodont skull. That cast will certainly serve well for it's purposes, excellent work! :)

Yeah, somewhere on here is another thread about this entire fiasco, as of right now there is 90ish pieces that all have to be given the treatment. Already started what is most likely a partial american lion (zero provenance or ID on that cast...and it was a victim of what I would call an unacceptable mold alignment) and will likely start work on about half a dozen various mandibles that thankfully only need paint, so can be done simultaneously. I won't even start to think about the hundreds of actual fossils that need proper work just to be stable for storage, let alone display and education.

 

A big problem I have is many of them were either painted with spray enamel (like this one), or are raw plaster which takes a week of stabilizing work just to get it ready for sculpt and paint. I learned the hard way that due to differences in expansion rates and hidden bubbles in the casts, I can't use my resin oven to speed the process along. I have a Castroides skull cast that "popped" while installing proper looking enamel on the incisors...was huge voids in the cast.

Anyone want to suggest a display stand style? I started with an oak plaque...hated it...tried a yellow orange sandstone slab...hated it.

 

Free floating was my vote but the boss shot it down as students won’t be able to handle it in the future for lab practicals.

FINISHED

What you can't see is the embedded neodymium magnets in the back of the tooth and the display frame....keeps it in plce for display, but is easily removable so students can handle it and such.
