How Brass Quoits Are Made:

The Flury Foundry in Lancaster, PA

 

 

                                                         

 

The Flury Foundry in Lancaster, Pennsylvania is one of only a few places in Lancaster county where quoits are still manufactured from scratch.  This small company is family owned and produces castings from several copper based alloys, mainly brass and bronze.  The foundry supplies a large portion of the quoits for the Ephrata East End Mart, an excellent source for purchasing locally-made quoits which I feature on another page of this web site.  I had the great fortune to receive advance notice from Paul Burkholder at the East End Mart that he was placing an order with the foundry for 21 sets of  four-pound quoits, in order to restock the store's inventory of quoits for the holiday shopping season.  He was gracious enough to arrange for me to visit the foundry while the order was being produced, and photograph the entire process from start to finish.  Jerry Flury, the owner of the foundry, notified me the day before the run, and at 5:30 the next morning, I met with him and some of his employees to setup this photo session.  I enjoyed the experience immensely, and am very gracious to Jerry, and to Paul at East End Mart, to make this page possible.  Thanks, guys!

I was able to capture on film all the steps in producing quoits, except for the actual creation of the plastic pattern used for the pour.  The pattern had been fashioned before the beginning of the quoiting season, so our tour begins at the molding machine,  where the pattern, mounted in a 'pattern board', is inserted into a metal frame that is filled with sand to create the mold.  Below is a photographic tour of the Flury Foundry and the detailed process of making Brass Quoits from raw materials.

 

The Pattern

     

Left Photo

A pattern is made by making an identical copy of an actual item which needs to be reproduced, usually out of an inexpensive material such as wood or plastic.  In this case, a hard black plastic is used to create the pattern containing two quoits, one with a raised letter 'A' and one with a raised letter 'B' on the top surface.  The pattern also includes all the paths required for the molten metal to flow through to reach the two quoit forms. You can see the bottom side of both quoits and the two risers and gates between them through which the liquid brass flows. The small white block just above the upper riser is the point where the pouring hole, called a 'sprue', will be made from the top of the mold to the surface of the two halves of the mold.  The quoits are actually orientated upside-down inside the mold, so this side of the board is facing up when the casting is done.

The top side of the pattern board contains a long runner between the two quoits for the brass to reach the gates.  The purpose of the risers and the extended runner is to provide reservoirs of extra metal which can flow back into the quoit cavities to compensate for any shrinkage of the brass during the solidifying process.

The metal frame which holds the sand in place is called a 'flask'. Luis Silva is seen here placing the pattern board upside-down onto the 'cope', which is the top half of the flask.  He will then place the bottom frame, called the 'drag', on top of the pattern board.

 

 

Making the Mold

 

                                                                     

A mixture of compressed air and a mold release agent is sprayed                            The drag is filled with a fine black silica sand.  A small wooden,      

     on both sides of the pattern board when needed to act as a lubricant,                      'press board' is then placed on top. The molding machine vibrates             

        preventing the sand from sticking to the pattern when the flask                                to settle and  pack the sand into the frame. The flask is then               

                            is separated.                                                                                turned over and  the cope is also  filled and settled.  

 

 

                                            

The whole assembly is then packed tightly using a large hydraulic press,                    The press boards are removed and the sprue, the access hole   

which swivels into place on the top of the molding machine.                                   through which the brass is poured,  is created by pressing

                                                                                                                                     a hollow tapered tube into the sand and then removing it.

 

                                           
  The Flask is then separated, and the cope is set aside while                     A small screen made of mica, called a 'strainer', is placed at the bottom

the pattern board is removed.  Here you can see the                                      of the sprue to capture any impurities that may be floating

Furnaces

Pouring Baille

 

                                           

The Pouring Deck contains four sets of tracks leading from the molding area to the left, behind the heavy plastic partition curtain. The crucible is place in a pouring 'baille',  a carrier which allows the operator to move it horizontally in front of the row of skids and tip it over to pour the metal into the sprue of each mold.  A helper places heavy weights on the top of each mold to prevent it from expanding or breaking apart when the pour is made, then removed shortly after.  Ed Smith and Junior Ocasio complete a pour along a row of skids in the two pictures above.

 


When the crucible is close to empty, it is taken off the baille and moved back to the furnace room by the hoist, where it is emptied of any remaining metal and bottom impurities.  It is placed back onto the furnace pedestal, the furnace is lowered down over it, and another shot is loaded for melting.  The second furnace is then lifted and the whole process begins again with a fresh batch of liquid brass.

 

 

Breaking the Molds

 

                                                             
Once the molds are cooled enough that the castings are hardened,                       The dumping platform then lowers backwards and the empty skids
