Chok tochot issue
I'm just starting a megillat Esther and I wrote a resh and the intended to write the taf (see photo) but just went a bit too far and it joined up forming a much longer resh.
If I scrape the join then is this chok tochot, as that is defined as forming the letter by means of scraping and the actual letter form is already formed and the scraping does not change the tsura of the ot - it is still a resh. My first thought was that I have to scrape back the resh to a vav form from the right to the left and then redraw the resh, but I'm not so sure since the form won't change even though I'm scraping?
Thoughts and sources?
