Speedmaster intake porting. Hopefully I can make something out of this

Hey John, how about a short video clip showing how you move the tool while you’re working. Your technique, if you will.
I tend to work up and down more than in and out. Just curious how some of you more experienced guys “handle your tool”......lol.


Lol. I’m not showing you guys my tool movement. That’s asking for to much. Lol.
