Does anyone know of a simple mitre saw that uses less than 900 Watts (240V). i want to be able to run it on a Honda 1.0i generator which is rated at 900W continuous, 1000W short burst.
This is the closest (but no cigar) candidate so far:
V). i want to be able to run it on a Honda 1.0i generator which is rated a t 900W continuous, 1000W short burst.

A small transformer would trim that down to 900w. But a 900w genny won't ru n a 900w motor. Gennys are specced in VA not watts, a 900w motor is going t o take somewhere around 1.2x900 = 1080VA continuous. Then there's startin g current, which might be 3x run current, perhaps 3kVA for a 1kVA saw. An i nvertor gen would baulk at that, an old electromechanical genny may be ok w ith it.
A variac is another approach, wind it up until it trips, back off until it doesn't.
I tried running a "900W" saw on a Honda EU2000i and it simply tripped out whenever you started the saw. A much older "2kW" non-inverter generator of unknown manufacture did the same.
You might get round that with a switch: start on 110v and switch to 240. Or given that load is zero during startup, a series dropper could do a similar job if no 110v output.
You can still get them on ebay, and surprisingly they are still made, albeit in very small numbers. There's no reason you couldn't run a saw on that genny, just not that saw _at 240v_. So expect reduced speed - but to what extent we don't know.
Or make your own tablesaw with a handheld circular, then you can come down on the power scale. It's easy to do.
I wouldn't rely on it working with the genny. Chances are that it has a start-up current far in excess of the 4 amps or so it takes under steady state conditions.
If your genny is like my 2.0i, overloading it - even for a fraction of a second - sends it into some sort of limp-home mode from which you can't recover without shutting it down and re-starting it.
