need some chopping help....

so I am removing my visor from the coupe (see pic) for a lot of reasons, but the best reason is that I don't like it. I need some help deciding what tool to use to cut off.... I need to cut a straight line, up against the windseild frame, so I can mount my new custom visor. Soo.... which does everyone else use for cutting looooooong straight lines....

• air nibbler
• air saw
• air cut off wheel
• other?

I don't want to use a plasma cutter as that would make the cut really ugly and the straighter the cut, the less work to mount my new visor.

 

Air cut off wheel. A new, large diameter one.

 

I'd clamp a straight edge on as a guide and cut along it with a cut-off disc on an angle grinder.

 

sheetmetal shears and a guide or nibbler .

 

straight edge and a metal blade in a circular saw , wear your goggles , its only 18 to 20 gauge, it'll cut like ****er , clean the cut edge up with a grinder . if you leave it a little long you can peen it over or hem the edge .

 

I'd use an air saw, then sand it back to a scribed line.
Cut off wheels make mess, and can get away from you.

 

clamping a guide is a great idea. I was going to scribe a straight line, but yes, a guide would make things easier. I am leaning towards a air saw first, air cut off wheel 2nd. I think the air saw will give me the most control, but the air cut off wheel would be the cleanest.
We'll see it goes, either way, I need to order a tool because I don't have any (air) cutting tools. Time to get shopping!

 

if you don't have the tools yet make sure you practice with them first . unless you have used them before.
