I've still got the rear wheel arches on my bongo that I'm breaking.

Already had an enquiry for them.

They are not brilliant but also not too bad.

Can anyone tell me how they should be removed...eg how they are attatched and how far they need to be cut away from edge of the panel and I might try to get it done.

On the other hand if anyone fancies a trip to South Lakeland they can DIY it.

Harry...if they are just a little bit rusty (even one bubble) it would not be worth the yime effort...best to locate some totally rust free ones.
The ones below were recut so there was about 3 or 4 inches to be welded in.

You can get special sheet metal cutters but for a one off job I would go the Grinder route Nick describes above...

Jeez - not half!

How do you prevent the whole panel from warping and buckling?

Niiiice.

It is a cracking job, having seen it in the flesh, you wouldn't know it'd been done =D>

The main problem is there is a double skin involved. so..you have two arches to deal with...inner and outer...also you need to strip out the inside panels so you don't set the Bongo on fire..cutting/welding the outer panel is normal bodywork..the inner arch is problematic...you cannot weld it so special adesives/sealers are used...all very time consuming...Some months ago there was a topic on here (one of the NW gang I think) he was quoted a very good price and the job was done well...however the guy who did it said the price will be double in future co's of the unforseen work...Still..at the end of the day it is the only way to get a proper job.

It really is incredible. What I can't work out is why someone chose to cut half way up the section for the fuel filler cap. Didn't that just make the job a whole lot trickier (though impressive as a show of skill).

Oh and don't even think of using cutting shears (in reply to a post higher up) would be my guess, as they will always pull the sheet metal out of shape as they cut . Use a thinnish grinding wheel and avoid overheating the sheet metal by not dwelling too long as you cut, in case it buckles.

I'm only guessing mind - never done a job like that! :?

Mike....they were as they came from the breakers...he cut very generously so I could use what I wanted....they were recut with "special cutters" so they were about 3 inches wide...
the shears work from above and cut/peel about 1mm out in a sort of coil.

Thank goodness for that! I thought we were talking about tin snipper type shears. Still sounds v clever that a device involving a 'shear action' manage it without distorting metal near the cut. Do they support the material adjacent to the cut perhaps? (I'll sneak a peek at Nicks link)
