Turning segments with carbide

I got all my rings glued up and started turning. I got a new gouge to reach the bottom of the bowl, it's a carbide one. I started using it and it just kept catching. I stopped using it on the bowl till I can practice on some scrap. Is there a trick with carbide?
 
Are you asking about the round tipped carbide tools ?
Where along the bowl are you having the catches?
 
Yes it's round and I don't remember the size but it was small. I figured the smaller one would take out less wood and be safer. I got catches all along the inside. I started at the bottom as it curves out, catch. Next I went to the top where it curved in some, catch. last I tried the middle, the 4 rings in the middle are almost vertical, still got a catch. I also rough turned the bottom half and top half before gluing them together. I'll try and add a pic of the bowl and gouge.

Here they are. I now wish I started with a smaller project for my first segmented bowl.
 
I set my lathe rest so the carbide cutter is at center or slightly above center. Just like a scraper.
I also keep the speed up and make light cuts.

I have one of these tools and use it lot, use at higher speed, and a light touch. Also a use a heavy thumb on top of the tool on the rest. Even with the wide part of the tool on the rest it does want to catch. However it is the best tool of any for those inside curves at the top of vases / vessels.
 
To help reduce the chance of a catch with a carbide keep the tool in a negative angle to the work piece.
