This can't possibly work ... I'm wired for 110V. If I plug a Voltage Converter to the wall to step up to 220, and run a tool or two wired for 220, is there anyway this would actually use less amps at the breaker than if i'd run the same tools at 110 with out stepping up the voltage?

Chances are it's going to use a bit more due to the losses in the Converter. -
It will pull double the 220 current draw on the 110 volt line plus the magnetic loss in the step up transformer which is what a converter is.
single phase to three phase converters operate on a slightly different mod then a single phase transformer does. They utilize a rotating transformer (typically a three phase motor and capacitor bank.)Art

It boils down to the amount of energy (watts) required to get the work done.
110 volts X 10 amps roughly equals 1100 watts as does 220 volts X 5 amps.
There are some pesky factors that complicate the math (loss through the transformer, power factor, etc.), but watts are what "gits'er done".
One good thing about using higher voltage is that you can use lighter guage wire (double the voltage - halve the current!).You might think I haven't contributed much to the world, but a large number
of the warning labels on tools can be traced back to things I've done...Comment

Any tool large enough to need 220v will be large enough to overload a normal 15 or 20 amp circuit. That's why it's 220 to begin with.
BTW, on tools that can take either, wiring them to 220v results in noticeably better performance. It's kind of like driving a car at 100 MPH; the Honda Civic is at maximum and the Corvette is comfortably cruising.Comment

All the outlets in the garage are on the same 15-20 amp circuit. Running the saw, dust collector, radio, battery charger, etc. should come close to the max amps. I haven;t blown the breaker very often but would using the voltage converter give me a cusion at the circuit breaker?Comment

The converter would make it WORSE.Comment

nothings free.
If you have a 110V tool drawing X amps to do a job, then the 220V tool will draw 1/2 X amps.
If you use a step up transformer, then the 220V tool will still take about 1/2 X amps but the draw from the 110V used to feed the transformer will still be X amps.
Actually, a little more since the transformer isn't perfect and there's some loss involved.
