ריבוע תיתורא
Is it מעכב if the תיתורא תחתונה doesn't meat up with the עליונה
How is it fixed?
How about the Bais of Uleovdo?

Klaff Tanning question:
I received this question via email. I am not really a klaf expert, I was wondering if anyone could answer this question: Dear Rabbi Gutnick, I am writing to you because a good friend of mine has put the idea into my head that the klaf in my tefillin were not really tanned and therefore are not kosher. He referred me to Megilla 19a re diftera. From the research that I have done so far, it seems that the klaf that is used today is tanned only with a lime wash. On all of the tanning websites I’ve seen so far, they say that the lime doesn’t accomplish tanning but only the removal of the hair and some other pre-tanning effects. Would you be able to explain to me or refer me to a website that explains how the tanning process that is used today takes the hide out of the category of diftera? Thank you very much.
Rabbi Reuvain Mendlowitz clarifies his position on Ksav Chabad (and my final thoughts)
Last week I posted some thoughts in response to a public lecture given by Rabbi Reuvain Mendlowitz regarding Ksav Chabad (the Alter Rebbe's ksav). I felt he did not represent the issue fairly, and since I had received questions about it from a number of people I felt it made sense to write a general response. After I posted my response on this forum, Rabbi Mendlowitz reached out to me by email and we ended up having a respectful and productive email exchange regarding the relevant issues surrounding Ksav Chabad. His position is a lot clearer to me now, and I think he also took certain things on board that I clarified with him. The purpose of the Stam Forum (at least back in it's heyday before all the whats app groups took over) was to connect sofrim from around the world, to promote achdus and build bridges, as well as to offer support and advice. In that spirit, I felt I should write a follow up post, to clarify some of the issues and misconception...
I'm not sure of the name but I use this type of clamp http://www.google.com.au/search?q=clamp&safe=off&hl=en&prmd=ivnsp&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMIpNjKnrm8xwIVYtumCh2GggSA#mhpiv=13
ReplyDeleteOne side does on the bottom back of the mabarta, the other on the front upper titura and it pushes it back in place so titurah elyona and tachtonah will be flush. You can even use it while you sew, and overcompensate on the other direction so when you release the clamp it will be perfectly centred.

the type of clamp is called a Bar Clamp. The link above isn't good, please google "bar clamp".
DeleteA clamp, even after sewing, will likely not make the upper and lower titura permanently flush. You'll most likely need to glue it once you get it lined up. If it's still off then you'd fix it by sanding. One who is experienced with batim work can easily handle this. As is, it shouldn't be used.
ReplyDeleteI don't think you understand the type of clamp I refer to. The link was bad, it's called a Bar Clamp, you overcompensate so that the mabarta is pushed so hard the non extended part of the titura sticks out (well) past the more extended side . If you do it for too long or too hard you may end up reversing which side of the ttitura sticks out more. I find this often works even without glue or shaving afterwards.
ReplyDeletePlease excuse my ignorance: what is the Halachik problem with this? If each part is "rabua" why must they meet?
ReplyDeleteI am wondering about the Halacha. Not aesthetics or practical. Just Halacha.
Thank you Eli, I'll just give it to a batim macher.
ReplyDeleteYY I was wondering the same thing but in zichron Eliyahu he says it's a problem according to some reshonim. BTW according to a''r the titura elyona is part of bayis as he says to sowe the titura with the bayis. Correct me if I'm wrong
Thank you Heshy.
ReplyDeleteI've been using a clamp (I'll provide an image in a new post as I don't know how to add an image to a comment) for years and it's widely popular among those who work with batim. On one side it has a perfect indentation into which the edge of the titura fits enabling one to adjust the titura. However, even after overcompensating, the titura will often slide back more than to the correct position again leaving a "lip" or "step", hence, gluing it in place once you have it in the desired position is strongly recommended.
ReplyDeleteI have a number of bar clamps as well. The ends are soft and it works well when I add a little glue between the bayis shel rosh at the bottom because it doesn't affect the paint on the Shins. I only slightly tighten it slightly so as not to affect the finish of the Shins and so the glue doesn't go too high.
