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.
clamp. clamp and more clamp.
ReplyDeleteyou can also try shaving off the sides and repainting
also you can put some foam in the shaidel which means the rosh is veryt snug and tight when inside, acting as a clamp 23 plus hours a day
and remember the shitos - hat the air between the batim is not counted so if when you squeeze the bayit togetther the ribua is ok its kosher-see ot yatziv
ReplyDeleteSo acc to this shitta (which BTW is pretty much Daas yochid), if I have a bayis with perfect ribuah and they are prudos with slight gaps (say each chatitz is open .35mm) and then when I squeeze them together the ribua goes off (ie 1.05mm), what is the din please?
DeleteShaving is the best, if not only, option to repair. clamping without glue is going to be temporary. tightening the sheitel is great to prevent it from worsening. If the gap is very wide then that could be a problem in itself, even if the overall ribua is corrected.
