I don't purchase a machine that doesn't have rigid tapping, but I do believe that form tapping is superior. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nzTd-oWrRcA.html I don't understand, do you sell taps? This isn't clear from your video, however, the fact you make a video at all about this subject suggests you do. I typically buy Guhring form taps....cuz they're just awesome. You should do a video on why people should form tap and what the advantages and disadvantages of form tapping are compared to thread milling and to traditional tapping, like you go over briefly in this video. Thread milling is crazy useful and it's VERY often overlooked, as is form tapping. People forget (or aren't aware at all) that those two are even alternatives.
