Having never tried my hand at metal casting I thought I would have a go.

I decided to try first on a small project to minimise expense.

Most of the "ingredients" I had lying around the place, the end result, while not perfect is, I think, a good start and I will use it as a learning experience -- ie watch this space for something more ambitious

Step 1: The Moulds (or Molds If You Are American!)

I used some modelling clay that (allegedly) sets in air without baking

I pressed in a small model of a dolphin to leave an impression, I then cleaned the impression up as needed with a small craft knife. (I also made a shark shaped one but more of that later)

You know I said that the clay air dries, well it doesn't so I baked it for an hour at 100C

Step 2: The Bookmarky Bit (OK I Don't Know What You Call It!!)

So I cut a few pieces of scrap stainless steel into triangles and bopped (technical term that!) a few holes in it for purely aesthetic reasons, and polished them up a bit

Step 3: Casting A.k.a What Could Possibly Go Wrong!

So I gathered the bits I needed.

The moulds

the bookmarky bit (still don't know what to call it)

some lead free plumbers solder

a Butane torch and a lighter

I melted it on a ceramic tile to protect the table surface

Step 4: Popped Them Out of the Mould

They look a bit rough (and tbh the shark looks nothing like a shark!) but we can fix that

"Igor - fetch the Dremel"

Step 5: A Little Bit of Dremelizing

So attacked with the dremel to shape and polish a bit

The shark has become a cod, or a pirahna or something but the dolphin is still dolphiny

Time to try something bigger and put the lessons I have learnt to good use

Vote for me 'cos I'm lovely!! ;-)

<p>Thes look neat! So, you melted the solder into the molds and stuck the bookmarky bits on top of them?</p>
<p>Yup - that about sums it up! I will make some nicer ones now I have figured out how it works (I'm thinking a semi submerged hippo)</p>
<p>Sorry,...major safety tip!! I forgot to mention the tin can gets EXTREMELY HOT &amp; my Dad used pliers to hold the can &amp; then pour the lead with it for the soldier mold.</p>
<p>As I said in the text &quot;what could possibly go wrong&quot; ;-)</p>
<p>This brings back old memories. My Dad used to cast lead soldiers for us to paint (w/oil-based Testor's enamels back in the 1950's). He used a metal 2 part mold, melted the lead on top of the stove in an empty can &amp; then slowly poured it into the mold. I'm not sure, but he may have pre-heated the mold in the oven so the &quot;pour&quot; reached all parts of the mold well.</p><p>Your clay mold idea is brilliant, but I was wondering if, instead of needing a propane torch, it would be easier &amp; cheaper to use your stove. Although, I'd put the tin can in an old baking pan in case there are any &quot;leaks&quot;.</p>
<p>I guess I could probably do it on the stove, but was in the shed for this as it was a bit of an experiment, now I know it works (without me setting fire to the kitchen) the old ball and chain may let me in the house!</p>
So the cast portion of actually made of solder? Very clever! (You might want to add a warning for folks with young kids to use a lead-free solder?) Thanks for posting. :-)
Thanks , I did put that in the text but maybe I should highlight it
