Cold Shop

About the Cold Shop

PGC has one of most well equipped cold shops in the country.  The studio is flooded with natural light and has plenty of table space for work. There is no project that is too ambitious for our Czech lathes and the arsenal of sintered diamond wheels available. PGC has been fortunate to host a number of world-class cold working instructors, like František Janák, Jiyong Lee, and Kathy Elliott.
