#4869 — [OT] Melting aluminum

http://ericlippert.com/2014/09/12/melting-aluminum/

   Today another in my ongoing, seldom-updated series of posts about
   building my own backyard foundry. Today I'll describe how the final step
   works: actually melting and pouring the metal. First, see my previous
   post on how to make a green sand mold.

   Start by assembling all the equipment you'll need in one place, on a day
   with no chance of rain. (Click on any photo for a larger version.)

Thanks for the link. One of my student holiday jobs was working in an iron
foundry (they made brake blocks for trains) so I got very familiar with
moulding sand.

Nice to see another hot-metal head [1] on c.m.  The term "hacker", in its
best sense, isn't limited to digital bits.


[1] Google my name and "blacksmith".

But you don't use aluminum do you?

The closest I got to any of this wsa making a screwdriver in metal shop in 
high school forty years ago.  Used a lathe to make the handle, and 
actually heated up the piece of metal for the blade and hammered away, 
then ground some.  A big screwdriver, I still have it, probably becasue 
it's only useful when I need a big screwdriver.

I always liked the notion of making a knife, folding it over again and 
again, then hammering, just like making croissants.

Don't think that butter and yeast are often used in knife-making.

But in both cases, you want slivers of both layers, so you flatten out, 
and then fold, then faltten again.

Only cold. You can do some nice repousse in Al but it's hard (where I
am) to  find pure Al sheet. The stuff they use for dump trucks and
boat hulls obviously doesn't work for that.

It's incredibly cool.  In the last 30 years, numerous guys have made
careers specializing in that.  I've made a nice little paring knife,
just to prove I could do it.

Almost but not exactly like making croissants, just to be technically
picky.  :-)  Cut and stack, not fold.
