Fixed! And Thanks!
Thanks for the advice, Joshua and Newboy. It’s much appreciated!
I tried fixing some of the issues you had mentioned, adding coarser screws to hold the frog down and making sure the iron was really razor sharp, but to no avail. Then I noticed the iron wasn’t perfectly flat, it had a slight bend across its entire length which wouldn’t come out under tension from the lever cap, I can’t believe I missed something so simple! Swapped it out for an iron from my #4 and it worked like a charm. Takes nice, smooth shavings and leaves a nice, flat edge and face. Now I just need to find another flight #4 iron and I’ll be set. Thanks again for the help, it’s great having a community that’s willing to help out people who are in a bind.
