AC motor speed controller on a MSW inverter
I want to power a 6 amp 115vac 4.5 inch angle grinder from my 800 watt MSW inverter, but have the ability to significantly slow down the rpms. I cannot justify a variac of adequate capacity, but ther...

I use an angle grinder with 60 grit flap sander to shape wooden surfboard fins. 11k rpm is just too fast and aggressive for the Lacewood I am currently working with. It is pretty much too aggressive for a harder wood like Ipe too.
A very fine touch is required. Slower speed would give me more control and not heat and expand the wood and I could move the tool slower and more precisely with less gyroscopic forces.
I'll probably get a speed controller for when I have grid power, and do a test on inverter power unless somebody says to not try it on the inverter.
I ask about the inverter because sometimes I like to park next to the Pacific all day long and time my surf sessions, and when I have a project I can work on and accomplish something, I feel less guilty for living the good life.
62 amps at full speed is a bit hard on the battery, I was hoping to get down to 2500 rpm and sub 20 amps.
I have a larger polisher/ grinder, with a built in speed control, but it is 12 amps, and is far too easy to overload the inverter. I fried my first 400 watt MSW inverter powering this tool at very slow speeds. Too much pressure or speed and it would trip the inverter requiring turning it off and back on. It is also too heavy for foiling smaller 4 inch shortboard fins.
This is lacewood fin with a carbon fiber perimeter and base. Epoxy saturated fiberglass.
