So are you using 35 units in a 24 hour period? So perhaps £7 a day if all at day rate £5.50 with 10kw at night rate? That doesn’t sound too bad to be honest Try reading the meter during the day and again after 2 hours see how much you have used?

I have never done any more than specify a same wattage vfd for the motor in hand and it all works…but if a bigger vfd is available at a good price then overspecify at will

Given that the invertek i linked to can supply 4.3 amps per phase and your motor only wants 1.27 they will be fine for your application and indeed if you upgrade to a 1hp(750 watt) motor

Buy one of these now…...

These are my vfd’s of choice now this is a 750watt one mind which will do fine...

A larger motor will be fine if you are thinking about larger bowl work but if its spindles and bowls< 9 inches or so then your 3/4hp will be fine as i said earlier running it on 240v will do no harm ( wired as it is...in star) less power but it will get your lathe up and running for the cost of...

You only need a small (0.55 kw) vfd to power that motor You MUST only Connect a vfd directly to the motor …not through any switchgear. The switchgear connects to the vfd control terminals Vfds can sometimes be tricky to set up do you know someone local tom you who can help?

Your motor if original is likely to be old as its not dual voltage (though you can run a 415v 3 phase. motor off 240v 3 phase with no ill effects other than slight loss of power) You can have the star point dug out to make it 240v but thats likely to be pricey if you cant do it yourself. A new...

I have 2 of the Chinese 2.2 kw spindles one in my cnc and one in a converted spindle moulder table as a router table…running a router in a cnc gets very tiring with the noise

No sorry long gone

3 amps should supply 750 watts easily (3 x 240) But inrush current on your motor may be as much as treble the running current so i would increase the fuse to 5 amps . And i would cut off the European plug and fit a good quality Uk 3 pin Ian

That’s a chuck for metalworking really though were used before the modern scroll type woodworking ones were developed. Chuck it and buy a woodworking one… Ian

It’s well worth watching “micro men” on YouTube a 2006 film about Clive and acorn computers

You will easily be able to put 2 hp through that belt... a A section single v will take 3 hp and a B section 5-6hp your biggest problem is getting the pulley to fit your new motor probably

Record power do their sc1 andsc4 chucks with an adapter for m20x1.5mm good price all in from snainton woodworking

Rattley is generally lack of lubricant on the quill drive..a good thick grease will quieten it down… if it still rattles when under load drilling then thats a different problem

Warm the centre with a blowtorch until it too hot to touch…lock the spindle and pull the outer edge towards you… remember its a left hand thread.

Very very sharp for the blades do you mean the finish is a series of scallops? ....maybe pushing the wood through too fast

The diagrams are cast into the box lid Your motor is 3 phase so only those diagrams match If you had a single phase motor you would use those diagrams Ian

Well take them off and measure the length so if the outside is 300mm then it will be a z290 or so or if its in inches 12 on the outside will be 11.5 so z 11.5 As I remember theres plenty of adjustment available Ian
