xsspeed Posted March 10, 2010 Share Posted March 10, 2010 Hey boes In the corolla I have some rust on the rear tailgate section - around lights and the 'car-side' where the boot latches. Now I would usually just attack with Mr A Grinder, but some of what I want to cut out is rather awkwardly positioned, or so small that in order to cut it out I will get a lot of over cut/cut into good metal which I would like to avoid. Just wondering what sort of tools others have used for similar jobs? I imagine some sort of nibbler or small recipro-saw would be the go? Cheers in advance - Steve Quote Link to comment Share on other sites More sharing options...
KKtrips Posted March 10, 2010 Share Posted March 10, 2010 Use dremel with an aggressive bit (or a blunt drill bit on a drill) and knock all the rusty bits off then rather than replace the metal just fill it with weld and grind it flat with a grinding bit?

RUNAMUCK Posted March 10, 2010 Share Posted March 10, 2010 You can get small air cutoff grinders, which are the size of a die grinder, but take a wee disc and have a safety shroud. They use lots of air, but are very easy to control, and cut nicely. Quote Link to comment Share on other sites More sharing options...
xsspeed Posted March 10, 2010 Author Share Posted March 10, 2010 reminds me I have a dremel kit now that I grabbed out of storage - will take a look and see - pretty sure its electric and not air (no compressor atm) Quote Link to comment Share on other sites More sharing options...
Mr.Mk1 Posted March 10, 2010 Share Posted March 10, 2010 Drill spot welds, cut pieces to get to pieces, chisel to cut and split seams etc. Its metal, you can always weld more in Quote Link to comment Share on other sites More sharing options...
Truenotch Posted March 10, 2010 Share Posted March 10, 2010 reminds me I have a dremel kit now that I grabbed out of storage - will take a look and see - pretty sure its electric and not air (no compressor atm) That'll do the job. It should have the little mandrel for cut off wheels already (Just a mandrel with a screw in the top) and you want the reinforced cut off wheels - Dremel 426 like this: Quote Link to comment Share on other sites More sharing options...
mikuni Posted March 11, 2010 Share Posted March 11, 2010 The other thing I have found really good in the past for this sort of stuff is the little air powered hacksaw. It does a nice clean job and can get into even the tightest spots - usually the spots that the grinder can't because of the different cutting orientation. The other good thing is the lower blade/cutting speed meaning no sparks - ideal for around glass or fuel tanks, although you would have to remove those to weld anyway. Heres a pic of a pair of identical tools to those I used (minus DA). Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted March 11, 2010 Share Posted March 11, 2010 That middle tool is the one I was (trying to) describe. I was well impressed by how user friendly it was to operate. I once made a mandrill to use a wheel from that tool in a reqular air die grider. But I found with no shroud is was a bit dangerous to use.

Bling Posted March 11, 2010 Share Posted March 11, 2010 Depends on the shape of the metal... but you could drill then tin snip as small as you want. So long as it wasn't too thick Or use a hole saw to save some time Quote Link to comment Share on other sites More sharing options...

forced Posted March 12, 2010 Share Posted March 12, 2010 You can cut anything with oxy aceylene. Just use a small welding tip and turn the gas up a bit, too much for welding but enough to blow a hole in and cut it. That way the melted stuff that doesn't drop out ends up thickening at the edges and is easier to join onto. A small tip can get into places that no other cutting tool can.

Truenotch Posted March 12, 2010 Share Posted March 12, 2010 IMO oxy makes too much heat for most panel applications, and when cutting around latches and tail lights there are lots of wires to burn. Quote Link to comment Share on other sites More sharing options...

xsspeed Posted March 13, 2010 Author Share Posted March 13, 2010 Unfortunately c@$h does not allow me to splash out on dewalt products - though we did use one of these (corded version I presume) to chop my parts cars up to take to the scrappies...like a hot knife through butter Quote Link to comment Share on other sites More sharing options...
