Well, I melted and created my first ingots today! While I'm happy my propane furnace was actually able to melt metal, I'm a little concerned with it's...
... Don t know if this helps? From what I can tell your Burner is operating correctly, or it wouldnt melt ally in the 20 min timeframe from cold.My monster...
Edyn The fineness of your sand is pushing the limits for green sand but it might work. You do have a lot of bentonite in it though and that would reduce the...
This is something that I wanted to do for a long time... I think I got everything I need to get started... I'm going to cast a gas engine block... Wish me...
Hello all, I am new to this hobby and am having trouble getting aluminum to melt in my charcoal furnace. The furnace is made from a large soup pot lined with a...
Hi Greg, ... Usually people send the air blast in through the hole at the bottom of the furnace... I suppose it would work to blow on the coals from further...
Thanks for the replies. From what everyone is telling me Ive got far too much Bentonite in my mix and 200 grit sand may be too fine also, Ill try and add some...
Greetings Guys, I've been working with Al for a while and have been approached by a few folks who are interested in having some small things cast in brass....

At 2000 the steel is pretty weak and dangerous as a crucible....use clay or graphite crucibles made for the high temp.....Fitz ... From: Ed Paradis...
Ray, what? Though individual grains of sand, no matter what grade, have basically the same porosity. The mixture of a fine-grade sand with a coarse-grade sand...
Jeff, Lets take the terms separately, first with porosity. If you think of a bowl full of marbles, each exactly the same size, the pore space is fairly easy to...
Permeability is everthing. Porosity is going to have more effect on the finish of the piece than venting of gases. Unless it's a critical suface, I cast a lot...
Jeff, I was able to access the file by doing a cut operation on the lecture6.pdf, then clicking on that lecture from the list. That may be because of a...
This really isn't a casting question but I hope there is someone with the answer. Is there a strength difference between 6061 T6 seamless aluminum tubing and...
Try heavier pieces of aluminum. I just melted down an aluminum propane barbecue lid, and it went much faster than cans. Cans have a lot of surface to oxidize,...
Can any Hobbicasters give some advise? Back in the early years of brass and bronze casting 200 years ago and more there were fluxes added to the melt to get...
... with ... In answer to your strength question, you did not say if you actually have the tubing and pipe in your possession or if you are looking at catalog...
Just curious, is it the alloy of the cans that makes them hard to melt or the ratio of exterior surface to mass? In other words do they melt better flattened? ...
If I have my notes straight, Borax is used for brass/bronze while chlorine is used for alum. I know that we used to use special tablets made for aluminum back...
I believe the cans are almost pure aluminum. They are definately an extruded aluminum product and none of them melt nearly as nice as castable aluminum. Yes,...
... Crushed cans definitely do melt better than their intact brethren, but there is still a lot of material lost to dross. I tried melting cans for myself...
I found a reference. Aluminum beverage cans are 75% alloy 3004 (bodies) and 22 % alloy 5182 (lids), plus some lacer and paint. Basically,mostly aluminum,with...
Yes. I had zip luck trying to melt them unsquashed. Even dropping them into a pool of molten aluminum. The flatter you make them, the better they melt. A lot...
Hi guys, What do you all like to do when melting down scrap aluminum that isn't clean (ie, paint, bits of other metals or plastic attached, etc.)? Do you just...
Why would you ever want to melt aluminum cans to make castings? The melted cans make an alloy that is not very fluid and has a high shrinkage rate. You will be...
From what ive been told cans and other aluminium like window framing etc are not very good for casting, The main alli used for casting purposes is 356 it has...
