Hi, I am trying to fab up some stainless fuel lines for a project using some 1/2"-.035 wall 304 seamless stainless line. I'm using a Ridgid 375 flaring tool. The problem I am having is that the flare ends up oblong or egg shaped. I think I am doing everything right though. First, I cut the tubing off square with a fine toothed hacksaw, then I clean up the face with a file and deburr the lip. Then I shoot some lubricant on the flaring cone and set the tube in the yoke with the edge flush with the lip. I put the dial to "feed" then rotate it until it gets hard to turn, then move the dial to "iron" and turn it a bunch then back to "feed" and back it off the flare. The thing is, when I have it on "iron", it feels like it's fairly easy to rotate but it always contacts a rough spot when getting turned which I'm pretty sure is the flaring cone contacting the out of round area of the flare. Any ideas on what's causing this? I haven't been able to find any information on troubleshooting problems like this.
