The International STa"M Forum

I was writing the name of hashem and went back to fix something and oy vey look what happened the regel became attached i was wondering if according to the tzemach tzetek this can be fixed

This new stuff called "Spray Klaf."  The claim was that it was Mei Klaf in spray form.  I have been using Mei Klaf(usually with an Eida Chareidit Hekhsher) for years.  I have never seen Mei Klaf do this.  The letters litterally are not davuk to the klaf.  I can erase them with a rubber eraser, and break them by running my fingernail over them.  Here is a picture of a Mezzuzah that I wrote with "Spray Klaf" treated Klaf.  The damage done occurred from simply rolling the Mezzuzah.

Excellent example of the yud touching the guf, most Rabbis passel this and don't allow fixing [chok tochos] in tefilin or mezuza. [In ST you may scrape away the whole yud and rewrite it]. Some Rabbis may permit scraping the negiya from the left side. Ask your Rabbi !!

I'd like to pose a conceptual idea that, even if some people don't get too involved as it's not completely practical, I think is important for STa"M anyway. I think there is value to determining the exact, perfect tzura of the otiot, even if it's not practical to hold written STa"M to that standard. Mishnat Sofrim brings from Beis Yosef that the nekuda tachtona of the Aleph should be 1.5 kulmusim from the top of the body. Traditionally I have always read explanations that describe this parameter as being the distance of the leg of the lower yud, as shown in the picture below (this is an aleph I've written previously, not for the purpose of this post so isn't geometrically accurate for this purpose). My STa"M rav and teacher suggested that this poses two potential issues. In order to comply with this, since the width of the gag and the yud are both 1 kulmus then it would mean that the total height of the Aleph would be 3.5 kulmusim, which seemingly...
