What I might suggest next time you need to trim the bottom of a door is to
clamp a straight edge to the door and use that to guide the skill saw. Also
be sure to paint the bottom of the door you just cut. A coat of primer
works fine. The idea here is to keep the end grain sealed to prevent door
About the time I had mastered getting the toothpaste back in the tube, then
I have used an angle grinder with wire wheel attachment for removing
paint from metal. Nothing else works faster. Yes, the wheels are
disposable and you need to stop using them once the strands of wire
start coming off.
I normally don't recommend cheap tools, but here goes anyway...
Four years ago - in a pinch - I bought a 4in angle grinder from Harbor
Freight for around $19. I subsequently used this tool to do a huge
amount of metal cutting on an old Mercedes I restored. This job
entailed hour upon hour of cutting, sanding, and wire wheel work using
that little rascal. Since then, I've used the same tool for scores of
jobs including cutting all the rebar for the foundation of a house
we're now building. Like the Energizer Bunny, this thing just keeps on
going. It hasn't even burned through the original set of brushes, but
HF tossed in an extra set to cover that eventuality. This is one tool
no shop should be without. Be careful though, it's an easy one to get
hurt with. I heard of a guy setting one down on the bench while it was
still spinning, only to have it whip around and slice open his gut.
Thrown debris and exploding cut-off wheels are also par for the course
- wear goggles or a mask and work gloves.

At work I just received a safety report that I think came from the
Australia version of OSHA on a fatal accident with an angle grinder.
The accident was still under investigation according to the report.
Apparently an individual was using the grinder with a wheel (not sure
of type) that was not designed for the grinder. The result was the
wheel exploded and pieces penetrated the individuals chest and
abdomen, killing him. He apparently was also either not using the
gaurd or was using in improperly.
