Rabbi Assaf Bednarsh-Hilchot Shabbat-Gruss Kollel-Continuation

Hilchot Shabbat shiur 43 (Rechitzah BeShabbat part 1)

Gzeirat habalanim (no use of hot water on Shabbat even if heated prior to Shabbat) applications including bathing, showering, mikveh and swimming. Note some of these applications involve issues other than heated water.,-boneh-part-1)/

Hilchot Shabbat shiur 44 (Rechitzah part 2, Boneh part 1)

Continues analysis of heated water: tvila, shower and dude shemesh applications. Begins discussion of binyan – anything temporarily built is not binyan duraita.

Hilchot Shabbat shiur 45 (Boneh part 2)

Door and window technology has changed – how do the gemara’s cases apply today? Reattaching (or fixing) items can be a boneh issue – what about unclogging a toilet? Even though the gemara says ein binyan bkeilim, there are a number of situations where we do say binyan bkeilim (various authorities have differing approaches on this question).

Hilchot Shabbat shiur 46 (Boneh part 3)

The closet/chest (not part of the building) technology was different in talmudic times (wood pegs could be banged in). When you bang it in (tkia) it’s a Shabbat problem but what if it’s not tight (rafui) or stuck in (mehudak)? How do these rules apply to made to be assembled items (one time v ongoing) such as brooms, glasses, salt shakers, lids, pack and plays? TBC

Hilchot Shabbat shiur 47 (Boneh part 4)

Continuing binyan/stira bkeilim. What defines a rafui (weak) connection? What’s the deal with legos? Do adjustable chairs/shtenders involve boneh? What about temporary supports? Then on to opening food packages. If making a petach yafeh (nice opening) is tantamount to making a kli, then how is the exception of mustikai defined?

Hilchot Shabbat shiur 48 (Boneh part 5)

Continuation of mustikai/binyan and stira bkeililm with practical applications such as soda cans, disposable containers, reusable containers, bottle caps, milk containers, widening an already existing hole and making a petach yafeh v a plain petach.

Hilchot Shabbat shiur 49 (Bonah part 6)

Is expanding a hole a problem on Shabbat? Is intent to reuse a package an issue? Is korea an issue with tearing letters/bags/container covers? Can you break apart yogurt containers? Is derech hashchata a matir by all wrapping or only by food wrapping?

Hilchot Shabbat shiur 50 (Boneh part 7)

What type of changes in a kli are so immaterial that they are not considered stira bkeilim? When is breaking keilim permitted? Are temporary openings permitted? Can you plug a hole with congealed oil? Are thumbtacks allowed?

Hilchot Shabbat shiur 51 (Boneh part 8)

Ohel kavua is duraita , arai is drabanan. If there’s already a tefach of an ohel, expanding it is OK. Lots of practical applications discussed (eg mechitzot, stroller hoods, beds). How are intent, type of use, and order of construction considered in determinig permissibility.

Hilchot Shabbat shiur 52 (Boneh part 9)

Defining ohel arai and applications to hats and umbrellas. We don’t reject well established precedents even if we think they are incorrect (and people get very wet).

Hilchot Shabbat shiur 53 (Boneh part 10)

Why wasn’t the recently introduced Shabbat umbrella accepted? Generally, the best approach is to leave such things open a tefach before Shabbat. Applications include: stroller hoods and umbrellas, awnings and garden umbrellas. Differing opinions based on how temporary it is, is it lshem ohel, and marit ayin considerations. Also discussed, righting an overturned tent, placing a straining cloth over a container, and putting a drawer back in its track.,-makeh-bepatish-part-1)/

Hilchot Shabbat shiur 54 (Bonah part 11, Makeh Bepatish part 1)

Are certain hats an issue of ohel? Is sushi making an act of binyan? May one braid or part someone else’s hair?

Maakeh bpatish – is the definition of one of gmar mlacha of any category that chazal deemed (a la R Asher Weiss). Also discussed, fixing hats or collars and the effect of being makpid.

Hilchot Shabbat shiur 55 (Makeh Bepatish part 2)

For a given manufacturing process, what does or doesn’t, constitute makeh bpatish? Can you use a clothes brush or a lint remover roller?

Other topics include: folding clothes, shoelace replacement, filling up (eg pillows, balloons), opening a temporary neck stitch and where does eino shel kayama apply?

Hilchot Shabbat shiur 56 (Makeh Bepatish part 3)

Practical makeh bpatish type applications including: watch (and toy) winding, tvilat keilim, truma/maser separation, and molid reach. Also covered: swimming, boating and hashmat kol.
