I know. I did save a few of the better ones and looking back I should probably have delayed action on a few more but they all came to me as scrap and were always destined to be repurposed. Call you later.

No mirror finish but it does buff up shinny pretty. I've many a video changed direction mid stream. Got a craft show this weekend, hope the weather behaves.

Thats for sure. We can do a scratch test. Also the aluminum alloy is usually very grainy looking. Thanks

@@CastawayMetals-BGr84u I have an aluminum alloy scuba tank that was given to me for melting. 3 hours after I began cutting it open, I had the top section off. This took several cutting discs (4") and 3 Sawzall Diablo blades. Needless to say, it remains in that exact condition to this day.

Yep, that would work also.

Here's a link to all my videos. youtube.com/@castawaymetals-bgr84u?si=n9jTdMhr9dz8uIJP But here's the one you are looking for. ua-cam.com/video/ZBYmN6oztec/v-deo.htmlsi=CaUUGXH-3nymO5Ol

Thanks for the comment. The lettering I used on the advertising side were little tiny stick on letters that had very little mass to them and were just inadequate for the job. Someday I might invest in a 3D printer or an CNC engraver.

@@CastawayMetals-BGr84u I'll be happy to see what you can do with these new toys when you're able to get your hands on them. Cheers!

Pewter has it's limitations as tableware due to its low melting point. That's why you only see it as serving dishes. Also it dents quite easily so the aluminum alloy was developed for casting many of the modern serving dishes, plates, cups and bowls.

I make programs to run on my pewter.

You can make just about anything that you can make a mold of. Check this video, then watch the rest of my channel. ua-cam.com/video/wqjofJcae_Q/v-deo.htmlsi=7Ka1voTlRXi0xlj9

Sand casting has it's place as in high temp non-ferous metals like copper, brass and aluminum. But for low temp casting you just can't beat silicone for replication of detail and ease of procedure.

To answer that all you need to do is watch through my playlist of videos. ua-cam.com/play/PLfaDdUxiOZ74S9BzbxSp8_S5-zztOqKY8.html&si=0gx2GruTpLeJzjxT

Yes, the melting point of pewter is about 450f, lead is 621f, zinc is 787f. Check out my other vids for sources.

Thank you for the kind hearted comments, they are very appreciated. Much of what I've learned is from watching others before me, taking advantage of their successes and learning from their mistakes as well as my own. I hope you sub'd because I've got plans for more videos.

I'd be happy to help out. And look at any pictures you have.

It sounds like the air in the mold is blocking the flow. You must give it a way out. That is why I always build the mold with an air channel. If you did make the air channel and strategic off cuts then it could also be that the zinc is not hot enough. I pour at about 800 degrees. It also flows better the second attempt because the mold is warmed up.

@@CastawayMetals-BGr84u Thank you

The only benifit I saw was improved flow and filling to detail in molds. I didn't really keep track of the percentages. This was just a low level experiment.

@@CastawayMetals-BGr84u Can you tell what effect bismuth had on the melting point of the alloy? Can you estimate what the melting point of the alloy was?

@@Cieniostworrrek I don't think I did a very good job on keeping track of some details on this experiment. The end results did not really impress me enough to delve any deeper into the project. If it had I would have revisited the mix in more detail, but No, sorry. At the time I considered 9 dollars a pound for bismuth very high compared to my zinc and lead which is practically free. Now days I'm working a lot with pewter which I'm routinely paying 9 dollars a pound so go figure. What is your interest in the matter?

@@CastawayMetals-BGr84u I want to make castings using the centrifugal method. I have just finished the first tests of the DIY machine. My test castings from tin and lead are OK, but I have a problem with zinc. Tin is expensive and lead is prohibited by the European Union because it is harmful. In Poland, I have a problem with buying the right rubber for zinc casting, the one I have does not withstand the temperature. I am looking for an alloy that does not contain lead and melts at a temperature below 350 C. Bismuth is used in low-melting alloys, so I thought that it might lower the melting temperature of zinc or ZnAl noticeably.

@@Cieniostworrrek I have found that zinc works in certain types of molds but not so much in others. That's why I tried the bismuth experiment. Zinc is rather gassy and doesn't do as well in a closed mold. I have much better luck with it in an open type mold. I've always wanted to try a spin casting system but haven't gotten that far. I think you should try pewter which you should be able to get a supply of where you are. The spin casting videos I've seen all use pewter. Pewter melts at about 450 f. Check my videos on MOLD MAX 60 .

That was actually wheel weight lead for this one. Signs like this will get clear coated with epoxy but I figure no one will be eating off of it in any case.
