I used the Eastwood spot weld cutter a few years ago when I was
removing the rocker panels from my MGB. The tool worked very
well, except that I went through quite a few of the replaceable
"cutters" that actually do all the work. Fortunately, I worked
ten minutes up the road from Eastwood at the time, so I could
quickly and easily pick up new cutters.
In my opinion, the tool is a worth while investment. I agree
with everyone who says you need to punch or drill a clear dimple
as a guide for when you first start the cut. The drawbacks, that
I can think of, are:
The "cutters" can be very fragile
The cost of replacing the cutters (order extras when you order
the tool) is annoying.
You still need to do a fair amount of cleanup (grinding) after
you've drilled the welds and removed the panel.
