Like I said, I thought about that, but it welded great for years with the last liner. I'm going talk with my local welding company tomorrow. It may need a whole new gun. But I'm going to try to file the opening where I cut it first and see what that does.

I dont know what they are called, but there is a tool out there to debur pipes
It's a simple handle with a square Z shapes bit

It bevels the inside of the pipe

If you know what I'm talking about, that tool may do the trick
