Well guys, thanks for the replies. My hand no longer tingles. I did
purchase anti-vibe gloves, and wrapped rubber weather seal around the
grab bar. I guess it works to some extent. Anyway, appreciate the
You might also get better tools. For example, the Porter Cable 505 is
a half sheet sander that has so little vibration that it passes the
nickle test. You can sand all day with no tingle when you stop.

The current Fine Woodworking Tool Guide also rates vibration levels
for orbital sanders.

Thank you. The sanders I'm usually okay with. The concrete angle
grinder is the worst. I believe it's from the acceration of the

Again, thank you.
Not normal, that could be indicative of Raynaud's disease (OK, strictly
it's secondary Raynaud's phenomenon, not the disease, but that's close
enough for Usenet).
An hour or two afterwards is typical. It's not good for you, and if
it's a regular occupational problem then you (or your employer) should
fix this, or you're at risk of future problems akin to "vibration white
If you're experiencing more than an hour, even after a long day's
grinding, then you have a personal physiological issue that's making
you extra-sensitive to it. Do you have "poor circulation", an unusual
susceptibility to cold, or does your skin turn blue white or red? Like
any of these exposure-related problems, don't ignore it today or you'll
pay the cost in a few years time.
If you're getting a couple of _days_ sensation afterwards, then you
have a problem.
As to practical measures assuming you're going to use the tools anyway,
then there's an awful lot you can do:
Change the process. If it vibrates, don't do it. Don't saw it, slice
it. Don't do it under power, do it more slowly by hand. Take up planing
by hand rather than using that noisy powermuncher. Quieter too.
Change the technique. Switch from a hammer drill to an SDS drill (more
drilling, less vibration). Use an abrasive flapwheel rather than a
Change the tool. Compare a cheap angle grinder and a Metabo. Compare a
delta sander and a Fein Multimaster. This is the one big reason why I
buy expensive power tools, not cheapies.
Change the handles. Many better tools (notably Bosch) use side handles
with anti-vibration inserts. These are also sold separately and will
fit other makers' models. Most of my own powertool handles are wrapped
in 5mm neoprene sticky tape, sold as pipe lagging.
Wear gloves - there are lots of anti-vibration gloves out there,
ranging from inflatable airbags (isolated, but poor control) to gel
pads (reasonable) or even deep freeze gloves (poor vibration
resistance, but dirt cheap and you've no excuse not to).
Limit your exposure. Stop for breaks. Don't use that technique for so
long in a day that you get "fizzy fingers" -- stop and do something
