One for the electricians

[gordon stephenson]

Further to to my grind and polish in one step, the ideal rev's (2500-4500rpm)recommended on the disc is much lower than my angle grinder. The disc can be used up to 12,200rpm but obviously this is far from perfect,

My question is what if I buy a cheapie angle grinder,and is it possible to run a 240V machine from a 110V transformer, to reduce revs and if so will it damage anything, First consideration as always is safety. I realise the load factor will be lowered but only envisage the grinder being lightly used,

Cheers Gordon.

get a variable speed polisher

Or pneumatic grinder. They are not that expensive.

I reckon the answer is sort of... Yes. The grinder will want to run at the usual speed, as the frequency is the same, but it will only be receiving half the power, so it will slow down easily. I wonder though, with it then being so inefficient and slow, will it heat up and burn out? The amps will go through the roof I imagine...

For a more sensible suggestion, see my reply in the polishing discs thread

Had one for a while and it's a damn good machine for the money.
