RF-45 Downfeed Lock Knob

Nice work there. I did similar on my milldrill but used a 3/4" end mill for the finger scallops. I also added a thin plastic thrust washer under the knob when I noticed the metal knob was getting scraped up when I tightened it. By the way, I also built a quick adjusting handle at the same time to replace the three spoke handle that I wounded awhile ago. Worked out pretty well too.
