i  purchased my foundry from foundry 101 as well . the standard kit will give you the basics for casting TG 's and butt plates .
 you will have to make your own patterns though .
 With TG I cast them  on their sides . Your  form will be  two pieces  a right and left side .
 The two sides must match  when placed together .
   One side is set in  the cope the other side  is set  in the drag .
 Once the sand is packed , the forms get removed . Your reservoir is  cut into the sand  in the cope . The vent and pour hole is set to match  the location  of the reservoir in the drag .
as to  the lugs you see on the TG's you purchase . These aren&#;t pour spurs. They are flow spru&#;s .
 They are connected to the reservoir .
As such once you have your reservoir set in the sand , you  connect that to  your actual part     by flow spru&#;s   . until you get things down  its best to have more flow spru&#;s . this insures that the part gets completely  filled . You also can add more vents  which also helps tell you that the part has completely filled .
 What the reservoir does is  keep the  melt liquid for a longer time  and thus helps  ensure you get a completely filled part .

  Ill have to look around and  see if I still have all the photos of my casting  set up .
 But at one time Foundry 101 had a tutorial on  sand casting .

As to your brass . Yes you need to remove the spent primers .
As to using a torch to do your melt.
 Trying to do it that way  can result in you burning out the zink in the brass rather quickly  especially if your holding the  torch right to the brass. &#;YOU DON&#;T WANT TO BREATH THOSE GAS&#;S IN &#;
 This can also happen with a foundry . It takes time to learn to read the  brass . As such  you can add more zink by simply adding a few pennies to the  melt  so as to keep your zink content up .

 Remember also  that you need more brass then you think  as  you have to fill the reservoir and the vents .
 This brass doesn&#;t get wasted . You simply melt it back down and pour it into ingots  or just save it for your next  castings .

Lost Foam casting is alittle different . For that you don&#;t need  a cope and drag .
 In simple terms , you make you part from  blue foam . The foam is then settled into the lose  dry sand  by either poring the sand around the part  and settling the form  OR  by means of settling the part in  aerated sand ..  From there you add your  pour hole and vent down to the parts .
A type of reservoir is still used on top of the sand . Again this helps keep the pour hot as well as apply pressure .
When the melt hit&#;s the foam , the foam is vaporized  and replaced by the  melt . Once cooled , you have your part

Brass Casting Basics- Everything You Need To Know About Brass Casting

--

Did you know that many people believe that brass is probably one of the oldest materials still in use today and that it may have been around since pre-historic times? That question may not yet have been resolved but one thing that&#;s for sure is that most people find brass to be one of the best metals to cast with. This is because of its unique properties which over the years have seen it used to make everything from coins to all manner of musical instruments.

Brass is, at its very basic, an alloy of copper and zinc. This means that it draws its intrinsic properties from the two metals and that someone, say a sand casting foundry, could vary its properties by varying the proportions of the individual metal elements contained within it. One of the main qualities that make brass casting so attractive is because brass has a generally low melting point. That means that the furnaces do not necessarily have to be too hot and it can be used even with the smaller homemade furnaces. In addition, you can easily graduate from brass to bronze sand casting since you simply need to add or subtract a few alloys from what you already have. Another reason why brass is still so popular today is because of its unique gleam and yellow shine. Many artists find this attractive and they use brass to make sculptures and jewellery, as well as many other decorative items. Of course these guys do not really need industrial grade brass for their purposes and scrap brass, which is much easier to find, should serve them just as well. But if the quality of the material has to be superb then they will be better off talking to a sand casting company that can present them with cheap manufacturing options.

Brass Casting Methods

There are generally three main methods that can be used for brass casting, although it is worth noting that most experienced metal casters will usually tend to experiment more with brass and may sometimes use a hybrid of the methods mentioned here. That said, the three most commonly used brass casting methods include;

· Sand casting- this is definitely the oldest way to cast brass and it is still very popular. It is a great option if you want a cost efficient solution and the final products do not have to look incredibly attractive.

· Die casting- this method uses a specially designed, reusable mold made of stainless steel to cast and recreate tons of identical products making it the most preferred option for large foundries that engage in large scale production of prototypes

· Lost wax casting- although it is more commonly associated with bronze sand casting, lost wax casting can also be used for brass casting as well as in casting of many other metals too. As the name suggests, it uses a wax model of the final product covered with a ceramic shell which is then injected with the metal to replace the wax and the shell finally chipped away to reveal the brass product.
