How many cows are used for one Sefer Torah?

As much as it sounds like a joke, it is a real question.

A couple of friends were curious about how many cows are used for one Sefer Torah.

So a couple of points here:
1. What is the average size for a Sefer Torah? (I know the layout is either 245 or 248 amudim or 62-63 yeriot)
2. Now, how many yeriot does one get from 1 single cow?
3. Based on number 2 how many cows do we use for a Sefer Torah?

Thank you everyone for your help as always!
There were a few end ך's which were questionable (had short גג) I showed a tinok all and he said end ך  for all of them, except for the end of לאבתיך he said, " enda vav.".  Any thoughts?


This was posted in a group. One suggested it was pasul and another that it was kosher. I tend to agree that it's kosher. I sent the image to a colleague, also a talmid of Rav Friedlander (and a moreh horaah in stam) and based on the image he wasn't sure how to pasken.

Double leather retzuot

Has anyone seen retzuot made of two separate bonded layers of leather?  These are not like the lacquered ones which peel like a tape and are passul.  They may not be the best retzuot, but it appears to me that they would be kasher for use.  Your comments please.

Devaluation of sefer Torah written by 2 sofrim

I've consulted with a renown rosh kollel Choshen Mishpat and dayan. He said that the fact that a sefer Torah is written by 2 sofrim affects it's value. I have a situation in which a sefer was commissioned from scratch through me to be written by a particular sofer. It's a basic mehudar ksav, retail price is 123000nis. He went ahead and had another sofer write the last 16 yerios. The ksav is halachically similar (basic mehudar) and is somewhat similar looking.
I'm leaving out lots of details but the bottom line is that a 2nd sofer finishing the sefer came as a surprise to me and I will be informing the buyer at the same time I suggest a price deduction. On the one hand the buyer may just want to "cut and run" and will accept a fair offer, as the sefer has taken a year longer than intended due to health and personal circumstances out of the sofer's control and if he has to (re)write the last 16 yerios himself we'd be looking at another 4+ months. O…

Drop of ink in reish

Found this tiny dot of ink inside the reish of asher. what are your thoughts? Is this enough to pasul the reish? Enough that it’s a sheila l’tinok? Or not an issue at all?

If the image doesn’t do justice - it’s really a tiny dot of ink.

I note that the yalkut hasofer of sefer mishnas hasofer writes under os daled: if a small drop of ink less than an os ketana fell inside the daled, then if a tinok reads it as a daled there is room to be lenient and scrape it away...

I wonder how small is small...

Chol Hamoed Question

Firstly, a gemar chasimah tovah to everyone, and apologies for the recent lull in activity. I'm sure everyone else has been busy as well. (This is the first time I am looking at this forum in a month!)
Today I was asked to repair a slightly damaged letter ( by moisture (probably spit)). I immediately noticed a large gap on the page,  after the word "bemisporom" which I thought may even be the width of nine yudin combined (which would be possul since it is acceptable as the shiur stumah, and there is not supposed to be a stumah there).
See picture below

After closer investigation it was determined that the space is not large enough to fit 9 yudin, but one could fit three large letters there, which is the accepted shiur stumah of rabbeinu Tam. Such a space is not possul but definitely somewhat problematic, as can see here in this excerpt from the L'dovid Emes (footnote 4) , who rules that one does not stop reading from it in the middle of the kriya, but one should not …

Gvil for a Sefer Torah

How to sew a Megillah according to all opinions?

What is the proper way of sewing Megillat Yeriot together?
I know that the Keset brings down the idea of Meshuleshet (28:10), but I am unsure what exactly that means...
1. Is that case only with regards when someone does not have enough Gidden to sew the whole Megillah or is it for any sewing of a Megillah?  2. If the sewing needs to be Meshulashet, does that mean it needs to be a number divisible by three? So that means 3,6,9 etc are the numbers that fulfill this opinion? 3. Is the number Megillah stitches equal to the number for a Sefer Torah's stitching? 4. Any difference Minhagim for Sephardim, Ashkenazi, Chabad?
As always, your inputs are helpful and I am extremely appreciative!

Leniency for sefer Torah that survived the Holocaust

I once heard that there are poskim which lechatchillah allow leniencies in  a sefer torah saved from the Holocaust. I've even heard that a Holocaust sefer can be used lechatchillah even if the majority of opinions render it problematic, so long as there is a "yesh lismoch",  it is OK to use. For all other sifrei Torah such a rule would only apply if you have already taken it out and found a problem during the laining (we can be lenient because of tirchei ditzibura).

Has anyone else heard such a thing and if so, can they please advise which poskim hold this and are there any printed teshuvos on the matter?


Kavanot of maaseh hamerkavah

I received an email with a request to post the following sheila:

I received a request from a potential client to scribe for him the kavanot of "maaseh hamerkavah." i have never endeavored to do this although the ktav itself seems easy enough. the question i have for the "olam" is if there is a specific sequence in which the maaseh hamerkavah must be written and/or specific amirot that should be said (similar to when writing a sefer torah, tefillin, mezuzot) -- basically, what, if anything, is required to undertake this project?

Something beautiful

Please see attached. I never saw anything like this before.
Does anyone know where this coming from?

New images of Megillah written by the Rebbe Mahara"sh

New high-res images have been taken of the entire Megillah!

They can be viewed at:

This is the only extant work of STaM  by a Chabad Rebbe that is still in its perfect original form.

There is another Megilla written by the Rebbe Maharash which is housed in the library of Agudas Chasidei Chabad. It, however, underwent an extensive "makeover" by a Brooklyn Sofer in the 1940s. It therefore has lost its original qualities.

G-d willing the complete Megillah will be posted in time the Yohrtzeit of the Rebbe Maharash - 13 Tishrei.

It should be noted that the Rebbe wrote of the Rebbe

"בקי הי' ואומן בכתיבת סת"ם. לכל אחד מבניו נתן מגילה כתובה בכתי"ק ... כן ישנם מזוזות גכתי"ק.
People mistakenly believe that he did not write מזוזות. This is clearly inaccurate based on the above testament of the Rebbe.

It should also be noted: people mistakenly bel…

Can I ask sofer to redo the work?

I gave my Sefer Torah for repairs.
This is one of repaired amudim.

List of shemot to Mekadesh or not

I found this chart listing the shemot that are Chol or Kodesh according to the Keset HaSofer, Kol Yaakov, and to הרה"ג הרב אלישיב זצ"ל as brought down in his Sefer נקדש את שמך

From the Or LaSofer online Forum for Soferim.

כמה חייב אדם לטרוח להדר במצות קביעת המזוזה

נשאלתי:  האם מזוזה שקבועה מאחרי הדלת או לפניה [פונה כלפי חוץ, ולא כלפי חלל הפתח], כי אי אפשר לקבעה בחלל הפתח כראוי לה לכתחילה, בגלל מבנה או צורת המשקוף. האם יש צורך לעשות מאמץ ולהוציא הוצאות יתר כדי לחפור לה מקום בחלל הפתח, או שהיות שאפשר לקבעה לפני או אחרי הדלת בדיעבד כדינה, אין צריך לטרוח יותר?
בהשקפה ראשונה נראה לי שהיות שבמצב ההוה אי אפשר לקבעה בחלל הפתח, אינו חייב לטרוח טירחא מיוחדת לעשות אופן שיוכל לקבעה שם ע"י חפירה וכיוצא בזה.
לא מצאתי מקור ברור לדבר זה לעת עתה, לא לחייב ולא לפטור.

וכן צ"ע האם יש במקרה כזה וכדומה - חיוב [חז"ל] להוציא עד כדי שליש יתר מכדי דמיו לקיים מצוה מהודרת? כלומר, האם מבחינה כספית חייב להוציא עד חצי מכדי דמי המזוזה, כדי לקבעה בסף בצורה יותר מהודרת, כשם שיש מצוה לקנות מזוזה כתובה מהודרת יותר, אם אפשר לו לקנותה עד חצי מדמי מזוזה זולה, כמבואר בשו"ע בנוגע לאתרוג.

אודה לכל מי שיש בידו להעיר בנושא.
