Making Aluminum Sand Rammers for Metal Casting

In this video I will be using sand casting to make aluminum sand rammers. Sand rammers are foundry tools used to tightly compact the sand in a mold. I designed these sand rammers to be more ergonomic than the design I was using previously.

I wouldn't have done it that way either, and I wouldn't of had to screw the board on either. I wouldn't have used the half pattern at all, and did it with a false cope with the full pattern, which I've done before. A lot less work, but he did a very good job.

It would be fairly easy to mill out a square void within the mallet head of the tool and pour in molten lead or bismuth, followed by a flat recessed aluminum cover plate hold in with flush machine screws. That lead or bismuth core in the head would make the blows way more substantial. You could also fill it with lead or bismuth shotgun shell shot to make it a "dead blow" type hammer. #7.5 shot would probably be good. :)

@@robinson-foundry for the first pour actually yes. The way I count my ammount that is needed for my 3d printed casts is to slice the part in slicer with 100% infill. Then the slicer gives you information about the volume of filament that would be used for the print. I just add to it about 20% for the sprue, runners and feeders/risers and I am ready to go 👌. Try it with your next project maybe it will help a bit. Either way I must say this project of yours was still a success! Good job and keep it up 💪

@lemguins7031 2 жыл бұрын

He needs the two halves of the sand mold to press together with a perfectly flat and even surface at the center of the mold where they close together (or else you get a sharp seam where they closed together). The easiest way to do that, would be to just put a flat bottomed half model in the bottom of the sand container and pack the sand over it, so it becomes the right shape when it's flipped over and you don't need to worry about extra steps packing the sand specially for it. You can't do that with a fully printed model, and you shouldn't put a full model on the top and pack around it because it would not pack well without shifting and no amount of careful packing will leave the top smooth.

Why not make two halves and use pins to hold both halves together when ramming up the other side? You had holes in the halves that could have been used for pins. Looks like a lot of work the way you did it, even if you did use a split pattern.

If you have a 3D printer you should be making 2 piece split patterns. I work in a Foundry. If you want the "best sand rammer" get a air compressor and a pneumatic rammer, but you do not need anything that hard unless you are making cores. 😁😆 I understand this is your hobby but you are overdoing and overthinking many of the processes here. The sand does not need to be extremely compacted, it can cause surface defects due to the gas not being able to permeate the sand grains. I could definitely give you some tips from my 10 years in the foundry business from pattern making, molding,coremaking,melting and pouring if you are interested shoot me a message if anyone has any questions.

Why did you take care in ramming up the first one, when it was going to be thrown away? Also, why not just ram a flat flask, and carve out the space for the pattern, if you’re going to redo it?
