Scud? I'm in the same boat, an 10" AGS project that has had to be shelved for the last eight months, thanks to illness and family demands.
My researches show 1hp to be under-powered, 2hp to be the absolute minimum and 3hp(plus) to be preferrred, especially if you take the saw to its limit of cut in a hardwood. I have a 2000W three phase motor that I'm thinking of either buying an inverter/converter for (££££££'s!) or perhaps carrying out the famous Steinmetz trick on it (MUCH cheaper). Might I suggest that, if you already have the three phase motor, depending on its power rating, you too might do better by the latter? I can recommend the 'Workshop Practice' set of books, two by Jack Cox - curate's eggs, good in places - but the one by Graham Astbury No47, "Three Phase Conversion"is superb.
Please also be aware that if you do chose to go down this route, even with a Transwave converter for example (deep pockets?), you will not develop ALL the power stated on the motor, but as most of the rating plates are artfully mis-representing the truth anyway, that shouldn't be much of an issue, provided it is a 'big grunt' motor.
P.S. You CAN run a really big motor on an ordinary 240V line - it's all in the RCD. Type C or D seems to be the flavour of the month...I haven't a baldy what my 20-year-old one is, but it takes a 1500W saw, 750W dust collector and my fluorescents without browning out or tripping.
Have fun!
Sam
