The burner is finished, I got the plans from http://www.backyardmetalcasting.com/index.html

It's a pretty simple propane burner, built from steel pipe for gas lines....cost a few bucks to make (the regulator with gauge cost about $40)

I hope to be melting some aluminum and brass sometime this week....not as loud as I thougt it would be, but it does make some noise <!-- emo&:D -->(IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)<!-- endemo -->

So far my "donor" aluminum scrap will come from some old used 2.0 pistons, a 914 steering rack, possibly an old 15x7 Phonedial that had a run in with a curb...of course I still don't know what the heck I am going to attept to make...

The neighbors are nervous

Looks like a bigass crack pipe. You better be careful.

Make some outside door handle flappers. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I can't wait to have a house some day so I can make my neighbors nervous with my smelting, welding, cooking bio diesel, etc.

Lead the way, Mike (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I think I'll start off with parts that are a "little" less detailed (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

those would be a PITA to sandcast, and building a mold for a diecast would be out of my abilities (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

I need to remove mine or find a set or rear trailing arms to get powdercoated...got all the front parts ready, just too lazy to drop the rear suspension (and still trying to figure out what color(s) I'll be using..........

I hear Jake needs a foundry to cast some badass heads. JK
I'd be a little concerned about the aluminum you are using. There are so many alloys designed for so many properties. I don't know if what you are planning to use is the best for your casting process. Anyway, you can make some parts but I'd guess that at the start they should be mostly decorative parts.

Maybe start by pouring some ingots for later use. Try machining / cutting a few and checking the quality of the casting.

And hey, go for it. We are rooting for you! We need a Mueller Fan Club smilie.

trust me, new heads are on the wish list.....chances are they'll stay on the wish list, but hey, it's a dream (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

for learning and testing the patterns and such, mixing of the alloys should be fine (as long as no zinc or magnesium gets thrown into the mix)

356 ingots are available for when I get serious and need good clean aluminum.....

I already have material for sandcasting (petrobond) and have read a few books on investment casting as well as lost foam and other methods....got to try 'em all....

The old 356's are mostly steel, and the aluminum ones are really valuable. Hate to see you melt then down. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

I wonder if they used 356 alloy on any 356 chassis???

Mueller, I did alot of casting in HS, aluminum, silver, bronze etc.
For the fog lite grills make a mold and then make a wax foglite grill and then make a pouring mold around than. Lost wax casting is really easy! Using the proper sand or other medium will take alittle work.
Are you sure thats going to be hot enough? We used a blower off a kirby vacuum along with the propane to blast the crucible toget it hot enough.

Get some gloves, tongs, masks etc. The metal will spit sometimes and hit you and that shit is HOT!!! burns right thru anything and HURTS.

I have a perfect first project for you.
A box
basically 2.25 inch by 2.25 inch

it would have a 2 inch hole in the box, leaving an 1/8 ich bottom...

And then a cool looking airfinned top...

I can explain and send the pictures I promised log ago...

It would be a good simple, yet precise enough project that you may have some fun with it.

The type of aluminum is not that critical...

In middle school we had a forge. For our projects, we just used to bring in aluminum cans and melt them down. Not a high strength alloy, but for learning, its an cheap and easy way to get your hands on a bunch of aluminum. Just think - after you finish pouring a mold, you will now be obligated to sit back and knock back a few cool ones to replenish your supply of aluminum.

I don't think Sherryl would like me "stealing" from her recycling bins (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (am I the only cheap SOB that'll pick up a can I find in the parking lot and throw it in my trunk???)

my goal is to "recycle" the aluminum from a 914 as much as I can......I'll have to get desperate for aluminum before I throw that spare GA 2.0 case into the fire (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

cool. how many #s will your crucible hold? i wonder what will happen when you mix a few different alloys? (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) are you going to try making your molds with Green Sand? you have to wear boots mike! don't burn yourself and have fun!
