the bandsaw has a 2000 watt motor, its a noisey bast**** eh! Lord above there is some scream from the thing
When I moved in, I sparked up the grinder one night, and the next day i called to the neighbours (next bungalow along) and asked them did they hear it, they said 'no, thanks for asking'
They mentioned that a previous tennant had started a printing business in the garage, and that he used to zap their electricity, so i reckon its just a crummy line.
My grinder is only 600 watts or so

Hi Richiew, I checked just now, my kettle is 2000 / 3000 watts.
Scratching my head here.
I rand the neighbours just now, and said I've a couple more cuts to make tonight (building a table, need good cuts) and that after that I'll sort it, I'll buy a generator.
So I need a gennie capable of powering the saw, probably that will cover much other stuff.

Adding an additional tank only helps in the short term. But it’s likely then the the duty cycle of the pump would be exceeded through the increase in time to fill the extra volume. The option to increase cfm is to change the pump and motor to something larger or add an additional pump similar to the larger machine mart compressors with two single phase motors/pumps or two or more compressors with the tanks linked together. Any of these options will increase the current requirements for you electric supply. When I was at college the recommended generator size for a single phase motor was to be at least six times the max run current of the motor. But a three phase motor this we reduced to three times the max run current. It may give you more options for a compressor and generator to suit your needs.

Ned, contact your electricity supplier, something is wrong.
You should be able to run a plasma cutter and compressor on a household supply, I would have thought.
What supply comes in to the house ? Amps....

When looking at generators look at the engine speed the 3000 rpm ones are noisey. Try for a 1500rpm machine.
a hydrovane compressor will probably be quieter too. you generator will need avr tootoallow for the load changes when the compressor cuts in.

Having run things off gensets (like our house with a Lister and much bigger properties off big gensets) the sort of genset you will need would be bigger problem with noise than your workshop kit.
As above, the starting current for the average mains syncronous motor is several times it's rated draw. My cut off saw draws 13 amps, but needs 45 to get going. A proper diesel genset usually has enough enertia to overcome the short heavy draw. The average petrol one, not. Keeping diesels quiet is not so easy. When off grid, we put up with the 'thud,thud' as part of the life. Our neighbours did too, as they shared it
Yours might not...
But, it does sound like your problems are not with the kit, other than a decent compressor like a belt drive twin. Mine is a bitsa like yours, but has no trouble keeping up with my 50 amp plasma. It only runs about 50% of the time. The direct drive 3000rpm are not only noisy, but less efficient in getting the air through.
I will take a pic of it. Maybe later tonight.
The two posts above came in before my slow typing got finished. The simplest short term would be a petrol compressor. Just keep it going and vent the spare air from a valve. But, likey you need your electrics sorted. Ours is pretty basic, but after switching things around, I don't have any trouble. The other half does, when loading the dryer, toaster oven and kettle on at once.... We keep torches handy in know spots that can be found by feel...

Sort of forgot about the photo, but here it is:
The twinpot compressor was left over from a golf course irrigation plant. Used to keep the air content up in a really big reservoir. Came with a 3PH motor, so swapped it for a Jetwash spare at around 2hp. The tank and switchgear were from a neighbour after the compressor cooked.
As things happen... my plasma let out (quite a lot of ) the important smoke today. Cutting small circles in 1mm sheet for a lighting project. While moving the jig, there was a pop from the plasma and flames visible, along with the important smoke. Bit of a lingering smell too
So, while I might be able to replace the condensor and the bits around... Likely to go for Stahlwerk's offering with a 7 yr warranty. The unit went to PlasmaPart a while back, but doing that again is about half the price of the new unit. If I do manage to fix it, then it goes on the dedicated table and the new unit does the rest.
Stahlwerks 50amp comes in at about €240 with spare tips (10) and shipping.

Fix your problem at the base.
Get a sparky in and let them check the wiring.
There is no way any electrical appliance you use should give the neighbours any interference. PERIOD.
You are getting yourself into costs to fix a problem that is not yours.
If the wiring in your street is that bad, then get them to fix it.
If you have a leaking sink the solution is to fix it, not just stop washing your hands.
