Been a bit of slow day... No jobs and no call backs...
So after my job search.. I went out and fired up ye ol' forge...
I have been meaning to make a bottle opener for a good buddy of mine.. He really liked the first one I made....
So I made him one... Learned a few things from the first... and now I went with that on a few other thoughts... This is what I came up with....

Originally I was going to use a piece of rebar.. but I would need to make a new set of tong to accommodate the stock size(not a problem, just not a whole lot of propane left and wanted a known doable project)..

Instead I just went with what I already had been using, 1"X 3/16-4.5" long...

very cool. I have always been in a foundry environment have always wanted to build one from old refractory brick and wool just to play small scale.

Thanks guys... This one really turned out much better....

I could use this as a furnace to melt aluminum and lead, if I turn it on its side, block it up with some bricks...

Maybe even melt brass/bronze/copper...But for the higher melting metals... Id be better going with a forced induction burner... then itll be really hot..

Overall, if you get the right brick or Kaowool and a good set up burner... it wont be that much at all....Could even scrounge up all the plumbing bits if your good at it...For me the frame was bed frame rail I found... I had a few of the other bits, had to buy the regulator...

Probably spent about $100 including a roll of Kaowool that I haven't used yet..

Or is it just another tool you want to mess with and getting a power hammer is actually on your list?

just wondering

My dad is a black smith he has 2 power hammers and knows how to make a knife really well.

I'd really love a power hammer.. either a belt drive or a hydraulic... Those I could figure to build myself...
Ultimately I'd like a Anyang 50kg... That only requires high voltage... And that's the shiz when it comes to powerhammers...

I worked in a ferrous metal foundry for a while doing mostly small production and prototyping work. We ran a pair of 1MW induction furnaces.

I've built several melting furnaces including rather large waste oil burner that would easily do bronze and iron. The hot facing was made of the refractory we used to line the ductile iron ladles at work. The leftovers got discarded, as it was highly hydroscopic once opened.

I never ended up actually casting any of my own iron at home, (why bother when I was allowed to at work) but that thing would melt down aluminum as fast as you could feed it in at about half power. I used the bottom halves of 20# steel co2 cylinders for crucibles. Downright hazardous trying to handle that much weight alone, but I had 10# ingots of aluminum master alloy (engine blocks and such) stacked up like cordwood and ready for casting for a while. Other things began to occupy my time... Took a couple big loads of aluminum ingots to the scrapyard when prices spiked, and ended up selling the furnace to an artist.

I sure wouldn't mind getting back into it now though, as I have far more suitable space to work with.

Glad to see more smiths around! I still do a fair amount of smithing, especially in winter, and we make the burners commercially.

My regular forge is made from the small propane bottle and lined with Kaowool, 3 layers. Until recently the paint on the outside was still intact after hears of use because the kaowool works so well.

When you get ready to build your hammer, take a look at the various "tire hammer" pictures and plans. Mine is a guided helve hammer with the "tire drive", 100 pound hammer and a 1300 pound sow block that is the tractor weight from an ancient Allis Chalmers front end loader. Enjoy your smithing, and if I can be of any help, just holler.....Joe

That's a nice set-up I would love something like that to play with. Maybe play is the wrong word, to practice with.

Thanks... the setup is easy... just a few bricks... The key is getting the right bricks, or they melt cause theyre not meant to handle the heat....
I did get Kaowool but didnt get the refractory clay stuff for it.. Im told its required in order to use it... So I just stuck with the bricks...

Burner was just some plumbing bits... really easy to setup....

I have been dabbling with alum scrap, easier to store and make ready for some upcoming sand castings this fall.

Bought this to try and now will build a bigger one since its fun need to be able to melt 5/7 lbs.

Nice setup...
I've been really thinking to get into a bit of aluminum...
I've got the forge, can put it on its side and just need a crucible...
I can get one relatively cheap off of the Amazon...

I remember alot of doing casting in high-school back in the day...
Green sand and lost foam... good times..

For all our typical need in the minibike realm... That's more than enough...

@mkutzy , @bansil ,
I was reading on another forum where a machinist makes chain/gear cases and other parts out of damaged deisel engine pistons.

Impressive stuff. A forge is on my project bucket list now...

Here you go... out on MBN http://www.minibuggy.net/forum/showthread.php?p=313442

Posts 16-18 show the chain case. It uses innards from a Toyota Hilux Truck transfer case.
