Summary of Shiur #787
This shiur discusses the final klalim of the Chayei Adam regarding
meleches boneh, specifically exploring the application of the
prohibition of building to food items. It analyzes the process of
making cheese whether shaping food into a specific form constitutes a
toldah of boneh or is prohibited only derabbanan. It clarifies the two
core aspects of boneh—combining pieces into a new entity and creating
a structure—to determine how these principles apply to items intended
for consumption on Shabbos.
Summary Shiur #786
This shiur discusses the melachos of Boneh, Soseir, and Makeh Bepatish

classifications. It analyzes the Chayei Adam’s psak, which is
somewhere in the middle of those opinions.

Summary of Shiur #783

which was demolished must occur in the same location (bimkomo) to be
considered constructive or not.
Summary of Shiur #782
This shiur discusses more details regarding the melacha of Boneh,
Soseir, and Makeh B’patish. The primary focus is the machlokes whether
the melacha of boneh and soseir apply to vessels (keilim) or are

soseir.
