    I was shocked that the tape showed up in the final casting. It's crazy how much detail can be captured with Petrobond. I'm guessing it looks much coarser on video than it actually is.

    Man when I got started, I stayed the heck away from zinc alloys like they were Cobalt 60. I was so worried about fumes, but also you know, growing up with industrial zinc castings being a sign of "this is cheap junk that they didn't bother to make out of brass"...
    And then you started on the ZA-12 journey, and I bought a bunch from rotometals when they started offering the small hobbyist ingots that fit in the graphite crucibles, just to see...
    Hoo boy. casting with ZA-12 is like having super powers, or a magic wand. Suddenly all the weird thin walls that were not at all possible can be right there in my finished work! The surface finish is great right out of the mold, even with *green sand!* (actually I get better finer finish with green than I do with PB, but that's down to particulate grain size and stuff - diatomaceous earth is extremely fine amorphous silica. You know, sand. SiO2. Just not crystalline, so very very very fine texture.)
    I don't Discord at all anymore - having fewer scattered socials accounts has been a good thing - but I ougtta make an exception and show you some pictures. Anyway, thanks for spreading the good word on the ZA-12. I have some thoughts about PID controller calibration on those electric furnaces, also, to get the temperature reading to be more accurate, but I haven't tried, so it's just speculation right now.

    Hurrah! It's that most wonderful time of year, when the Gingery gets a drop of progress! xD
    For your drain/air holes, you can just use a scrap of randomnes on the floor to dip in the wet resin, an drop it on the hole, then blast with a UV torch add another drop, and voila, hole magically gone forever! :)
    Love the results, that's done really well, quite impressive results with that alloy, and your much improved sand casting skillz xD
    I wanna agressively push the idea of adding complex engravings onto non-important surfaces, with few button clicks, for free, so the pieces are super personalised, and easy enough to sand cast (or lost resin cast even) :)

    So... aluminum *can* be vibration damping, but it requires adding enough silicon to make it hypereutectic (>12.5% Si). The excess silicon forms a granular precipitated phase, similar to carbon nodules in cast iron, and has a similar damping effect. But you need a lot of it. Silicon also helps with fluidity and shrinkage, since it expands on freezing like water. Though it does also require higher pouring temperatures (700C or higher).
    For shrinkage, you have 3 main options: Reducing thickness in problem areas (which you did here),adding big risers over the problem areas to act as feeders, or adding chills by the large sections to drive directional solidification. Or, mix and match for greater benefit!

    Paul,
    Thanks for another great video.
    I think there's a lot to be said for a casting that's rough but good enough. The new casting is pretty nice though. I do want to put in a plug for using pure zinc as a substitute for cast iron.
    Zinc has a density of around 7.14 g/cm³ while Zamak 12 has a density of approximately 6.0 g/cm³. And zinc is very, very close to cast iron. The density of zinc is around 7.14 g/cm³ while the density of cast iron is typically around 7.20 g/cm³.
    Keep up the good work.!
    Cheers from Alaska

    I have a natural distrust of zinc alloys, on paper zamac has great properties, better than your typical 356 aluminium, but in practice every piece if cast zinc alloy I've worked with has been a mess. It corrodes like that's its job, you'll have to think about galvanic corosion where it contacts those ways, maybe include a sacrificial annode.
    I hope you have a better experience with Zamac than the zinc alloys i've had to deal with, I'll stick with brass for now.

I also have the first 4 books first editions. Pretty sure gingery just updated those books. On most things anyway. But good job.

    So a trick they used to do on cast iron parts and i suppose modern cast steal parts today is anything that matters, like mating surface, they will cast oversized and then machine down to size. That reduces rejects and reduced machining. I suppose you don't have a mill but you do have Sanders.

    • @tobhomott
      @tobhomott วันที่ผ่านมา +1

      Yes, to this day foundry patterns for all cast parts (nonferrous as well) that will need to be machined still have machining allowance built into them. If they didn't, and machined castings still reliably fit their designated locations and performed their functions properly? Why now THAT would be a trick! 😁
      The old man did include machining allowances where necessary in the plans for the all of the patterns for the machines in his books, rest assured. The Gingery milling machine isn't until book 4 though. First Paul has to finish the lathe from book 2 in order to machine cast parts for the shaper (book 3)... Maybe we'll see it happen one day. I'm the last person in the world to doubt it - I built the charcoal furnace from book 1 in 2013 and I *still* believe I'll build the lathe one day!

    • @PaulsGarage
      @PaulsGarage  วันที่ผ่านมา +1

      even with the wrong aluminum alloy I would be able to do it with a HUGE improvement. 95% of the issue is the mold making. the "mystery" aluminum is actually scrap A380, not the right alloy but not horrible. The extra shrinkage from aluminum (and then even more for a380) could be fixed with a feeder like I describe in the video. Actually i cut out the detailed explanation because the video was too long, but it wouldn't be hard to do.

But I also know how well theory translates to the real world the first few times you try something, even if you spend the time to really do the math first there is always little bit of artform/experience in making the perfectly calculated actually happen in the real world. So the question really is do you have the knowledge/feel for that harder material to cast?

    I don't retain much information when watching a video, but did you mention what sort of sand you used all those years ago on the first casting? I remember a time when you switched from Petrobond to green sand and then back again. Nice casting by the way (pun?)

    Should go watch the precision casting they do with inconel jet turbine blades. Coating the stuff with thin coat of plaster and using something like lost foam or lost wax pattern can end up a with almost flawless part. Zinc alloy people used to call pot metal and considered almost garbage. The aluminum alloy they use for casting isnt complicated, its like Aluminum plus some amount of silicon.

    looks good enough to me , if you where to have (a friend with) a milling machine you could machine it to perfect size , then again you could cast a solid block and just machine it intoo the shape you need
    thats actually a pretty large piece you casted using that small melter makes me wonder if my home grid would be able to take 3 of those running at the same time ..... and enough time to cast all three intoo one mould one after the other
    sumting i allso wonder about and might be usefull when the lathe is done : i seen people cast aluminum rods using a metal seamless pipe , after cooling the alimunum schrinks enough to fall out , problen is that you can only cast this long a piece with the amound of aluminum per melt and or the length of the pipe used and there inclusion or porious bits in there that show up when machining the part
    wat i was thinking was to plug the bottom of the pipe for the first pour and while the aluminum is still somewat malluable put it under an hydraulic press and press it partway out of the pipe , this should compact it some and should make the aluminum a little stronger with less inclusions , after that keep pooring more amuminum in and press it out a little further after each poor
    probably need to experiment alittle for the amount of time needed to cool the metal enough to compress it without making the claylike aluminum shoot past the press toward the top and still have it hot enough so it doesnt stick intoo the pipe once cooled , might allso experiance problems with inclusions or even the different poors not welding together intoo a single long bar
    might be interesting to try out for a video

      The slicers all include an estimate of filament consumption and even print time, but with multicolour prints depending on the exact method it can start to get really quite wasteful in filament. So if you want a huge number of colours might I suggest just printing in white and investing in some acrylic pen markers so you daughter can get any colour they like relatively quick and cleanly even if she isn't really ready or interested to handle paintbrush. I've not tried them myself but the Speedpaint markers seem to be well enough liked by the folks that have tried them.
