Hi there, life has been incredibly busy that is why I have not posted anything and may come back to KZbin eventually. But to answer your question, get your diameter of your circle, then your pitch, so your space apart the holes need to be. Once you figure that out. Find your centre line and dot punch that marking. Scratch your first “dot” “hole” along your diameter circle line, then work off that going around each dot until you have your five, but you have to figure out your space apart. It’s hard to explain it on here and much easier in person. I hope that helps at all ☺️
