Compared to this I think the chain tied around the car axle is a lot faster
AND SAFER!
Setting ones pants on fire is no laughing matter!
For safety's sake...put the wife in the car with her foot on the brake and
when it comes loose have her DUCK and HIT the brake! Or hit the brake and
duck....whichever works for you.......

so watch out for where the debris lands. You are going to have to use a
plunge cut to get started and then push the cutting wheel from left to
right - they don't like to cut against the rotation of the wheel and you
should position yourself with the grinder at about belt height so that you
can use your body weight to control the grinder. You are going to have to
control the depth of cut yourself, this can be done, but it takes practice.
Just remember, if you can cut steel quickly with these things then you can
certainly cut fibreglass!

you are going to have to take it really slowly and not just bear down on it.
This would heat up the steel and work harden it almost to the point where
you cannot grind it at all.
Work away at several area in sequence about 1/2" apart, it is going to take
time.
I don't know how big your chainplates are, but you will need several
Flexcuts to get this job done.
