How to avoid catch turning a segmented bowl

Hey all.

I'm turning my first segmented bowl using a standard 8 segment setup. I've smoothed out the outside just fine, but moving to the inside I got a catch that pulled the bowl off the chuck. HELP! I immediately realised I have no idea what technique I'm supposed to use. I've seen plenty of videos of people using carbide scrapers, but I am using a standard bowl gouge. The bowl is walnut/maple and 9" diameter on the top ring if that's important. Should I be angling the gouge the same as I would if I was turning a solid blank? Any tips greatly received.
