Oh but you can! The entire build is right here: ua-cam.com/play/PL2DTpv1ZquENyuUirwEPuYjW4uhPsfQJ7.html. Hope to see your work soon, for some reason I really enjoy pouring videos . . .
yes cool, the one guy asked what was a flow glass or sight glass, we told him what we in the chem processing plant use one for, flow or level of liquids. cool cast too, others have used a large riser so you can pour faster. you make a tube from the green sand with a large hole leading down to your cast. you will need to cut off the lenght of the tube used to pour but it works.
flow sight glass is used to make sure a liquid is flowing and not gelled up or even hardened and blocking the other fluid from flowing. another use is to see the level in a boiler other wise the boiler could run dry (low water level) and blow or ( high water level) and blow. hope this helped
Thanks Doug, after having a short pour with a 20lb crucible, I didn't want to screw around. Final weight (sprew and all) was 29.5 lbs. :^) The ingot was 3 lbs. and we probably spilled another pound or so there at the end when the crucible bobbled out of the shank . . . I need to fix that.
The sand is bonded using sodium silicate, which I can make a lot cheaper than buying. It's a lot easier to use too. I added a link in the description for how I make it. I plan on posting how I build a mold with it soon. You can check out SV Seeker where they have this sort of thing posted.
In this case we will be pulling an alum based sludge through an 8" pipe for a dewatering centrifuge. Due to small scale testing we are concerned that we might pull clear water through channeling in the sludge. This will let us know if/when we need to stir or sparge the sludge.
Good job however I would recommend pouring just a tad faster. Best bet is to gag the pouring cup. That mould looked a lot like resin bonded sand. What brand?
So I think I get it. Since you are not pouring with too much frequency, making the sodium silicate yourself is easier/cheaper than greensand? It obviously paid off, your big pour here worked like a charm. Is there anything else in your sand? Just dry sand?
+Jim Jones you got it. I haven't poured anything in quite some time, although I do have plans to. If I poured a lot then I would have to rely more on green sand, as it is I don't have to keep it stored anywhere. All I used was dry, sifted play sand, sodium silicate and a bit of carbon dioxide. Another benefit I might mention is once the mold is set up you don't have to pour right away - no worry of the sand drying out, I'm sure a mold would be good for months after setting up.
Awwww, man!! I wanted to see it milled up and polished! That is freaking AWESOME dude!! Well done. Time to start making sodium silicate. :)

Well done Rod. That was a lot of aluminum.

What is a flow sight glass?
Great idea having the cradle under the sand and just lifting up.
marvelous!
thanks!
