How to cast pewter into simple Hardboard/MDF moulds. This is a method for simple shaped objects with no undercuts. Its my first instructable so go easy on me!
Stuff needed:
Small sheet of hardboard, any off cuts will do.
A fretsaw (hand or powered)
Leadfree pewter, which you can buy online.
Blowtorch, or small camping stove.
Wood glue.
A clip for the hairslide or a piece of dowel about pencil sized.
Solder and soldering iron or pencil torch.
Polishing wheel or dremmel.

Step 1:

been making an embossing stamp. with lead. how does pewter compare with lead. in terms of detail hardness and melting point. I'm not fussed about alleged toxicity issues because I was born in the 80s so iv built up a resistance.
Very well written instructable with a clear set of instructions. <br><br>As a person who casts as a precious metals fabricator I'd like to add a my 2 cents.<br><br>1) What you also can do is put a layer of carbon on the interior of your mould. You can do this by using any dirty flame (kerosine flame, or a very bright Yellow/ Orange flame on an adjustable oxygen/fuel gas torch, etc...).<br>This will give you a nice and smooth, non-stick surface in which to cast.<br>Obviously you can do without as this instructable proves.<br><br>2) when you are casting into your mould it is best to keep the flame on the molten metal as you pour. This prevents any oxidation and discolouring from forming and also helps reduce rapid heat loss in your molten metal. Also it slows down the cooling and setting of the metal in the actual mould (rapid setting of the metal creates a large crystal structure which can break away from itself as it sets - Cracking forming around the sprue and holes/ pits appearing when you polish)
<p>nice tips </p>
<p>Simple and to the point, thank you. But I'm lucky to have a small Cnc for the mould design.</p>
<p>its allright could be better</p>
<p>very nice, thank you.</p><p>When making your mould several tiny air channels should be cut radiating out from the mould for air to escape through. On a mould this size three per side would work best. This prevents any air pockets or blow back/burping through the pouring hole which could potentially burn someone.</p>
<p>Great advice, but it is not entirely true that modern pewter contains no lead. It depends on where you buy it. To be safe you should only buy pewter from a reliable source. And as the saying goes, if it seems to good to be true, it probably is. Steer clear of suspiciously cheap pewter. One example of this is the &quot;pewter figurines&quot; often sold in dollar stores, which are almost pure lead. </p>
<p>A warning to anyone going to try this: If you're using old pewter mugs, cutlery, etc., be aware that they could well contain lead - and that's not good to handle, ingest, etc. Modern pewter contains no lead.</p>
Excellent instructable, I'm hoping to get into casting by trying pewter casting first. This has given me some wonderful ideas! Thanks for sharing!
Great tutorial. Can you tell me the cheapest place to find Pewter? <br>
Thank you. I'm a rank beginner and your instructions were clear and really made sense. I think I can do it. jal
Thanks, let me know how you get on <br>Cheers
Sorry, didn't even know I was on &quot;cheers.&quot; ?? jal
excellent - I have done this many times at school with children - You are safe with a little care.<br><br>Suggest pouring the hot metal over a small tray filled with dry sand so if any is spilt it isn't going to run off the table and down the front of you.
Thanks for the reply, the sand sounds like a good idea. <br>
I'd suggest doing away with the sand though. Once sand gets into your metal it becomes difficult to get out. Just a bowl/ tray would work fine.
Hi folks, Ive added a couple of pics of soldering, hope that helps.
Very nice. As you learn new skills and techniques, please feel free to create more instructables. I'd be interested to read about some more advanced molding and casting.
It'd be nice to hear a little more detail (with photos) about attaching the clip, or photos of the dowel holder.
this weekend I will take some pics of soldering, the clip &amp; add this. <br>Cheers
Will do, thanks for the comments.
Nice 'Ible! well written.
