This video shows a sofer writing a sefer Torah. This sofer has a good hand, writes at a nice pace, and can ask a decent price. But one can also tell how the sefer Torah industry has commercialised the process, allowing for better productivity.
Note the following:
1) The sofer is writing on a light table, which means he does not have to worry about planning the spacing and can just trace over the letters. This saves a lot of time. This also minimises mistakes and saves time of repairs.
2) The quill is a plastic kulmos with a repository, which means you need to dip it into the ink every few lines instead of every few letters. Also you do not need to sharpen it and make new quills. Both of these save time.
3) The klaf today is more refined and smooth, easier to write on. Not uneven and rough like the old days. I'm sure lots of "mei klaf" is added. This enhances writing speed and quality of writing.
4) Double sirtut. Again this enhances quality and neatness.
5) The tagin / crowns will be added afterwards by a metayeg with a repidograph. This saves time and money, and means that the sefer could be finished sooner. For 80 - 90 shekels per yeriya you can get beautiful tagin done.
With all the above new "inventions", the sofer can write approximately one omud an hour. With good results. That means on a good day he can write two yeriyos and can easily complete a Torah within 6-8 weeks, from beginning to end. This is somewhat the norm in today's market for Sephardic Torah's, where sofrim are expected to write 4 seforim a year. Someone can work on the crowns while he writes further yeriyos. The checking is easy and clean, probably more is achieved in the computer check (spelling and negiyos) than a manual check. Erasings prior to corrections are done by a third party who specialises in making quick and perfect mechikos. No need for the sofer to fiddle with this, wasting precious time.
What you end up with is a professional, beautiful, clean , easy to read, faultless and mistake free sefer written in a fraction of the time that it used to take.
