Hey Martin. I really enjoyed watching this video. Not so much for a how to guide. But more so an education on how others do this type of work. I can quickly understand your passion for sticking at it for so long. Right back from the start with the use of Skirting Boards. To custom made high quality cast boxes. It,s funny how the obvious has a way of escaping you for so long. Until one day you have that satisfying light Bulb moment when it all comes together for you. Looking forward to watching the next part of this video. Peter.

Peter, You are not wrong about how the obvious escapes sometimes, I find one way to prevent this is to listen to what others suggest - even, and in fact especially, those unfamiliar with the work as they have a completely different view point - at times they come out with utter nonsense but other times some very good ideas. One always has to be open to new methods, products, systems etc. as otherwise you just get stuck in what John Campbell calls the 6000 year old technology of the foundry. The upcoming series on actually making your own moulding boxes will I believe surpass anything so far seen not only for ease of making but also flexibility of use - well, I think so but then I guess I am a little biased😊 .....

Olfoundryman: hi Martin my experience has been that having a similar shape with 10"x14"x21/2" was a great size with junk aluminium one piece with that clearance enabling ease lifts also the pin height is needed to be at least flush with the cope height so you can use your thumb to press down as the for fingers lift this enable an easily controllable lift for the list inch or so. Hand feel is an all important feature i agree… One piece are good too for flatness twist stability till they are dropped to many times when knocking out and inevitably a corner cracks open rendering that box half useless. Hard sand with a step joint is a good option bit it cost you in reclamation equipment. Sometimes the improvement in reject rates easily justifies the increased sand costs. But yes, green sand with sturdy boxes has an awful lot to be said in favour of it simplicity wise and smooth finish! thanks for sharing your experience's.

Hope 2020 sees you in good health! A possible suggestion! I noticed you're not a big fan of sodium silicate cores and only use them when you forced to, due to poor breakdown etc. I use sodium silicate for both cores and molds as its more convenient for me, no mulling etc. as I have no garage or place to work. I mold outdoors or on the kitchen floor. People and quiet a few textbooks say sodium silicate reacts to the Co2 in the air and cures over time. This is not true! The sodium silicate simply dehydrates and hardens to almost full hardness, but if you chuck the sodium silicate bound sand into water it simply rehydrates with the water and the sand falls to the bottom. Simply make the mold or core and leave it outside (hot weather) for a few days, weather and size dependant. I've left them up to a year with no ill effects. The mold develops almost full strength of gassed sodium silicate and is completely dry, but when poured only the first few mm's in contact with the metal cures. When the metal solidifies simply put the complete mold into water and the sand falls to the bottom. In Campbell's books he describes something similar which industry is now using as its easier to reclaim the sand. The Co2 method is the fastest for mass production but hard to reclaim the sand. If you still want full strength after it has dried simply put the mold in the oven for an hour at 200 degrees C. I discovered this as I had no CO2, and left the mold sitting for a month before pouring it.

@olfoundryman8418

4 жыл бұрын

Christopher, I solve the breakdown problem by adding 1/2 a percent of glucose powder to the sand just before adding the sodium silicate. After casting the core will wash out particularly if you use a hose. The glucose slightly weakens the core. The problem I find with air drying the core is that it has such poor green strength that it is very hard to get it out of the core box in one piece so it can be air dried. I prefer shell cores because they are stronger (much, much stronger) store indefinitely are quicker and easier to make and they have good breakdown they also seem to provide a better finish. The finish from 70 AFS sand in a silicate core is very poor - the same base sand as a shell core is a lot better... Martin

I would like a little more of a gentle taper but with the hard pins its very slow to put on (die grinder in a lathe!) so the bevel had to do…. Martin

It's great that you kept all those prototypes and cast-off boxes all these years to show now. I learned a lot and I'll guess others did as well. Are you going to store them on a top shelf in the back of the shop again, or make a gift of them to someone? Please don't let anyone accuse you of being a pack rat and toss them into a bin. 🙂 👍

I'll be watching this a dozen times to absorb everything. But you presented a coherent way of thinking it through. Basic principals. Much better than drawings. Looking at all you have shown. A drill press with a proper table support so it doesn't flex. Yes most drill presses are not really rigid. And a nominal 12" disc sander will do most of you machining. A file and some simple flat filing tricks similar to filing buttons but to keep you on a plane will keep you flat on the mating surfaces. Disc sander for the edges and squaring up. You can also cut aluminium with normal saw blades. Just rub parafin wax on the blade sides whilst it is not turning and you will have a bit of lubrication. Repeat as necessary. My 0.5 cents Awesome video. More information in this than in a few of the casting books that I have. Must have taken some time to make. I appreciate it! And good to see you back in action. My best wishes for the new year.

Mark, In the planed part 2 of this video the approach we have taken is much as you suggest ,we have planned it so it uses a minimum of tools and any tools in the "not usual" category (a 12mm hand reamer and a 3mm tap for example ) are readily and cheaply available via sites like eBay. We have assumed that most people have access to a drill press and a 3d printer. We are hopeful that there will be very little machining or even disc sanding necessary - some parting line filing but little else. The box we will come up with is a combination of the good features of the preceding 55 years worth. I think you will like the design.... Martin

Usually when it gets anywhere near this bad the humidity is below 10% and a screamingly hot north wind blows hence the fires. Our eucalypt forests just explode.

I was surprised by the slop fit of those bolts. It’s probably caused by the fast and cheap method of rolling the threads on. But I wonder if you would have had better success with studs. I can see how they would create their own problems, but I’ve used and run into enough studs to know that they do go in straight. Perhaps the thread count has something to do with it. I’ve noticed that all studs have a finer thread pitch at the base.

@olfoundryman8418

Sheminger, Studs may well have worked better, some of those bolts were a bit cheap and nasty! One thing I have noticed is that the pins work better (much less tendency to grab or to corrode) if they are hard. Hence my preference for induction hardened shafting to make the pins from - the shaft I use is meant as the inners for linear bearings. It is hard straight and very smooth. - Ideal... Martin

Phil, I am glad that you enjoy the videos and thank you for saying so. Quite a few people have suggested the book idea. And I have been tempted sometimes as many of the books out there are so full of errors as to make me cringe. Many have useful information too but the real difficulty is that any book I have seen contains a mixture of good and bad! - the trick is to know the difference, but if you do you do not need to read the book. 😏 I might add the same goes for just about every YT video I have seen some are absolutely appalling even from very popular channels (sigh) Unfortunately I am not a long project person and a book is very definitely a long project also I am a terrible typist and a book would take forever but I have not completely abandoned the idea - maybe one day!....

I faced the same problem with the unbalanced boxes. I dont have a circular saw. I had to use my router to make the wood the same size. I think in 99% of cases its just the missing tools which obstruct the making process.

@olfoundryman8418

4 жыл бұрын

Greg, I guess that I just started with green sand - it was what everyone used back then (1960s). I don't even know if petrobond had been invented. I have many times considered trying petrobond as it is very useful for plaque work, but it has some problems;- Many people do not like the oily feel it has, The smell and smoke on pouring, That it supposedly needs proper mulling to keep it in good condition, That it is expensive ($4.00 per Kg out here) - I use about 400 Kg of sand so that would be a big investment, That it slows solidification down so mechanical properties of the casting tend to be lower, That you have to try and get rid of any sand that was against the metal. It has its advantages of course, the main one seems to be better surface finish but my green sand will give a better finish than petrobond any day.....Martin

@olfoundryman8418

Жыл бұрын

Bobby, Because the pins and the holes they had to go into were so ordinary I had to leave the pins loose so they could move a little to accommodate the inaccuracies as the two box halves went together. I could indeed have used Loctite but I fear the pins would not have gone into the other holes unless I took great care to align the pin with the holes - and that was the problem - I had not done proper alignment up front. The idea of threaded pins seemed so easy so clever etc but it turned out to be a disaster. The pins are the hardest part of any moulding box. I speak from bitter experience... Martin
