Best cut off tool?

Post by sogatha »

Hi all
Any recommendations for a decent cut off air tool?

First time at this (got to start sometime) - I’m going to fit a boot hinge repair panel and rear floor section.
Presume if I’m butt welding these I have to be extremely accurate with cutting out and wondered what the best tool is.
Thanks
Pete

Without seeing where you're contemplating cutting, I can't really suggest much in the way of cutting tools but often with tricky places, you can always make several cuts in to the rotten part to allow what ever tool you are using to get in better and end up with what you are after.

For Butt Joints, I actually like to have a gap between the 2 parts. I'll do some test runs to see how much of a gap, but it's at least 1 mm and probably closer to 2. I generally use a MIG but not always. Then when welding, I'll put a copper block in the side that's not seen or difficult to grind, then weld in the gap. When ground back, there's weld material that's at least the thickness of the material either side. For some joints, I have a few copper blocks that I've put grooves in to, which I align with the weld, then grind back both sides. The copper blocks will let you weld on that edge without it disappearing !
