There are things like getting the sand ready the day before helper(s) turn up and currently I am not able to do this as it is physically demanding.

Gabor, Thank you for your comment. Yes, I try to follow the great Guru John Campbell although I have many questions some of which relate to how one can and how far one should adapt his work to the small scale moulds that we hobbyists work with. I wish I was young enough and in the right position to do the sort of research work that you are involved in. The foundry industry needs all the help it can get from people like yourself. Have you published any of your work - I am always keen to learn more and read all I can find..... Martin

I am always excited when I see that you have posted a new video. I'm glad that you still have more videos planned even though they will not include actual casting. While I have learned much from your casting videos, I welcome any new videos about the things you have learned about casting. When I was in school we had "Shop" classes to teach hands on skills. I remember one term was metal working, that included sheet metal forming and aluminum casting. I ended up taking taking an electronic technology course in college and was fortunate to have worked for electronic manufacturing companies. The first year was in the testing department of a large telecom factory. The next 12 years was at a tiny electronic shop where I we had our own line of alarm panels, and we also did some custom design and manufacturing for other small companies. I did design, purchasing, assembly, testing, customer support. I learned a lot there. I then moved to a small (but bigger) electronic manufacturer as the senior electronic designer. After 25 years there I finally retired last month. I have always been interested in design and manufacturing processes. Working for small companies, I didn't get paid a lot, but I was involved in all aspects of product creation. I have a small workshop at home (lathe, mill, etc.) and had used it often in project development for work. About fifteen years ago I made myself a small electric furnace to do some metal casting. I decided to start with zinc based metal due to the lower melting temperature and because I could get away with using welded steel pipe (thick walled) as the crucible. The first attempt was pretty spectacular, due to the sand being too wet. The second was a little better but still too wet. The third attempt went pretty good. I had a 125mm injection molded timing gear as a pattern. I knew the draft on the part was insufficient, and the outside perimeter flange was too thin, but I just wanted to cast something. Because of the lack of draft I think I had a problem with one edge contacting the other half of the mold when I was reassembling it after removing the pattern. A little shifting of the sand. There was some shrinkage in the center. I plugged the drive shaft hole in my pattern and I did not provide a riser. There also was some shrinkage on the inside of the rim where I had my gate cut. It had a little rough finish, but I was surprised at the level of detail retained. There was a small circular paper label on the inside surface and it is clearly present in the cast part, along with the molded in raised part numbers. Unfortunately that was the end of my experiments in casting until last year. I did a couple of items and incorporated many of the things I learned watching your videos. Still there were flaws but every flaw was explainable. And a learning experience. With my approaching retirement I decided to purchase a few different size crucibles so that I can cast aluminum. Only the smallest size will fit into my existing electric furnace. (4"x4"x9" inside dimensions, made for my 3.5" o.d. steel pipe) I have made up simple, but proper, lift out tongs and a pouring shank for the new crucible. I hope to give them a try withing the next couple of weeks. As I stated, my current small furnace is electric. I live in Canada in an area where half the year is cold to very cold. This is one of the reasons I prefer an electric furnace. In my basement I have a small welding chamber that I can use in the winter. It has piping and a fan to exhaust welding fumes, with a minimum of heat being pumped out the building. (with -20°C air replacing it) I still have enough insulating firebrick to make a bigger electric furnace but I am concerned that it will take too long to get the aluminum from melting temperature to pouring temperature. Over the years I have been collecting aluminum at work. When we scrapped sheet 3003 aluminum for discontinued parts I would collect it. I also collected a lot of heatsinks, 6063 extrusions, from returned or scrapped production. I had assumed that I would sell off the aluminum and replace it with proper alloys for casting. A couple of months ago I was surprised when I came across some research papers where 6063 was used for casting tests. Investigation of Mechanical Properties of Aluminium Cast Alloy (6063) By Varying Chemical Composition www.irjet.net/archives/V5/i4/IRJET-V5I4689.pdf Effect of casting mould on mechanical properties of 6063 Aluminum alloy jestec.taylors.edu.my/Vol%207%20Issue%201%20February%2012/Vol_7_1_089_096_WASIU%20AJIBOLA%20AYOOLA.pdf Modelling the Mechanical Attributes (Roughness, Strength, and Hardness) of Al-alloy A356 during Sand Casting (one compared alloy was 6063 aluminum) www.ncbi.nlm.nih.gov/pmc/articles/PMC7040807/ Because of these I decided to give the 6063 I have a try before bringing it to a scrap yard. When it comes to casting videos I like they never seem to include putting a hot ingot on a block of ice, or into a bucket of water in a plastic pail. What I want to see is a part being made. I don't care for metal muffins or pouring molten metal into water or ant hills. What I like to see is the pattern of the part. Why it was made the way it was, if there were any casting challenges. Cores for example. How it was gated and risers used. Ramming sand (unless special precautions need to be made) and pouring metal generally I skip. I like to see the cast part and the attached gating and risers. Anything that would explain why the pour went well, and why it didn't. When I look at a part to be cast I think about solidification, where and the path, until solidification. I appreciate the Oldfoundryman videos, and a few other channels that produce quality casting content. I hope that when I ever make my own videos that I would provide good informative content. (sorry about the length)

Rudy, I am guessing that you are from the "French" part of Canada - not that it matters of course. I know of the Canadian cold - not first hand but both my parents were Canadian, Mum from Winnipeg, Dad from Agassiz BC and both often spoke of the cold and how glad they were to be in a warmer climate 😊. But I would love to be able to visit Canada as it looks to be a truly picturesque place. Re 6063 those articles seem to give a confusing idea of the hardness with readings from 30 Hb to 80 Hb. At 30 the material would be like chewing gum and thus unmachinable 80 would machine quite well. However 6063 does not have any significant eutectic in its structure and thus you will struggle to get a good sound casting with it - you will be making it hard on yourself by using it. My suggestion is that you sell the 6063 to a scrap dealer and with the proceeds but some 356 ingot - much easier to cast and if you give it a t5 heat treat like I do it will machine very nicely indeed. You should really watch the ramming as it is an important step - assuming of course that you can find someone who does it right (I do of course 😊) This channel does it pretty well too d. lazlo Pouring you should always watch as it is what makes or breaks a good casting I do it right but I am about the only person who does - the ladle (crucible) must be low, the metal must move as closely to horizontally as possible into the mould. You are right though to want to see the casting running system and all . Its nice to see the top of the casting too as that's where the shrinkage will likely be apparent -hence the on the block of ice people rarely show the top😊.... Martin

@@olfoundryman8418 Maybe your Mum and my Mum passed each other on the street one day. At least your Mum was smart enough to leave Winnipeg. Yes that's where I'm from. Lived here all my life. About the 6063 articles. I thought they were pretty odd. My thought was that it might work for decorative castings. Like plaques that some people make. But I have no interest in making plaques. I might do an experiment using the same pattern and do pours with different alloys. While I don't know the alloy, I do have automotive aluminum castings that I have acquired. All labeled as to what they came from. Wheel rim, intake manifold, water pump, etc. As far as watching the ramming and pouring stages. I have carefully watched you videos, many times over. Sadly there are not a lot of other channels that are worthy of repeat viewings. I saw one video this week where the guy took his copper ingot, previously cast from copper pennies, and recast it to a copper sledge hammer head. I have to say that his video productions skills is top notch. Oh, yeah, back to the casting. He cut up the ingot into pieces to melt and it was interesting to see all the porosity revealed. It was worth it watching just for that. You don't know what is inside until you look.

So glad to tap into your wisdom yet again Martin. Was getting worried as so long between posts, now this is superb info which I will take on board. Many thanks

Great to see you back Martin! I've been an occasional caster for over a decade. When I started out I was probably making all of the mistakes you outline here, over the last 5 years or so I've been incorporating the methods you show on KZread into my work, and I can definitely see the improvement. I still have some way to go and I'm sure if you were to see my videos you could point out a number of errors (some admittedly due to my own laziness). Your videos are my (and I'm sure many others) favourite source of casting information, I know you've been suffering with health problems and it may be a while before we see you back at the moulding bench, but more videos in this type of format would be equally welcome.
