Forgot to clamp my v-band together before welding now surface not true. Very minimal gap . I'm worried because my o2 sensor is very close and don't want air to affect it.What is the best way to true both up? I tried fine file cross hatching and getting close but need another method.Thanks

I always used a flat file on mine. It took awhile. Did you do a continous bead when you welded it??? I always do little spot welds on opposite sides and i let it cool down inbetween.

Yeah had it spot welded then went to town on it. Guess I can keep working it, might look for a new larger fine tooth file. Thanks

Let us know when you fix the issue. I know someone with the exact same problem.

U can always saw into the pipe enough to get pipe to bent a little and rewelded the pipe. If u do it close to the old weld it will just look like a bigger weld.

Have a chop saw? Can face it with the side of the saw disk.

This will give you a square cut.

Once I get it closer to acceptable I will give it a try.
Not the problem its the actual v-band surface thats a little warped. thanks
Need it perfect so both sides match think chop saw might be to risky. thanks
wasent the pipe cut that was bad just too much heat to the flange at once it warped but very little. Thanks
