[Vwdiesel] Impact Tools

[Val Christian]

Strolling through Walmart, I stumbled upon their automotive clearance
bin last week.  A set of deep 1/2" drive metric sockets were there for
$12 (Campbell Hausfeld), so I decided to buy them.  The size coverage
was better than my SK set.  Actually they look better made than my SK
set.  I wonder about the metal.

After deciding to get the sockets, I noticed a CH impact wrench
(PL250298), which claimed to develop 450 ft lbs.  For 25 years I've
used a Ludell impact wrench I bought at Two Guys for $20.  Tests 
show that it develops about 150 ft lbs, although I'm sure the packaging
said 250.  In any event, it won't always do axle nuts, so I still 
get to use my breaker bar.  But it is very handy, and having a lower 
torque, I don't have to worry about my teenage kids breaking wheel 
lug studs when they help me.  

The impact wrench was marked to $60, so after a week or so internal
deliberation, I went back and bought one.

There are a couple of questions which come to mind...I haven't really 
seen a discussion on impact, except that some of us have such tools,
and some don't.  Does anyone know of a general FAQ dealing with impact
tools?  Are there any discussions or reviews on cheap impact tools?

There probably isn't a week that has gone by in the last 25 years or more,
where I haven't used an impact tool, air powered drill or air chisel.
I'm still interested in learning a bit more.  Any suggestions?
