[Amps] SB-220 troubles

[Scott McGrath]

In my case aviation with the ATC suffix Heavy - In general aviation you 
screw up and we read about a SK who's other hobby was flying,   in 
commercial it leads on CNN.

The safety habits learned last a lifetime also the fact that screwups 
are inevitable the trick is that you need to make MORE than one to cause 
injury or death.   Saying one will never make a potentially fatal 
mistake is one giant step down the road to that mistake.

For my restoration work I have a air manifold I have three types of air 
available

1 - Air with oil mist for air tools
2 - Filtered Clean Dry air for painting and sandblasting
3 - Shop air

All air lines have different incompatible connectors so it is impossible 
to use the 'wrong' set of hoses or supply.  I never have to worry about 
my finishing hoses having oil in them and ruining a paint job and I 
never have to worry about using an air tool for an extended period and 
blowing it up due to lack of lubrication.

Heck I own a shopsmith 510 and that has just minimal guards and safety 
systems which I check regularly I like it as it has sufficient safety 
for a reasonable man but no excess guards which get in the way of 
getting the job done.
