Thor, or should that be Zeus?

Domestic properties are often supplied with a 100A fuse these days so that about 23Kw. The neibours electric might not like it though with the lights dimming etc.

Ive read that these can be upgraded but then of course all the relevant conductors need to be suitably sorted. For us being in a rented place has limitations.

I have looked at getting a workshop with 3 phase but anything near London is very expensive.

We are looking at moving away from London at some point but not there yet. This may limit Thor in the end with a 4KW spindle setup.

Fair-do's, you have to go with what you can do in the end ;)

At least with such a heavy built chassis, a later upgrade would be on the possible list.

Yep.

I am currently also looking at 'better' quality spindles than the cheaper ebay ones. So perhaps only still 4KW but potentially better.

Ive contact HSK and looking at getting a price for a Giordano Colombo unit. Pity the air cooled units are so noisy.

You mean 4kw direct drive spindles? Or belt driven BT and similar by 4kw motor?

Cause if first i dont see a reason why not to go with 4kw water cooled spindle. less than 400$ now that you have the drive. Bearings are cheap to change one day. What would bring the more expensive ones to the table that the Chinese one can not do??? for 1/5th or 1/10th the money?

But if i was to make it BT30 driven i dont see any option save servo driven. Why to put so much money and effort and not be able to do rigid tapping and similar??

Yep, at the moment the likelyhood will be either -

Just use a Chinese Spindle, I have the VFD already.

Get a BT30 Spindle, belt driven and use the same Chinese spindle to power it. This allows me some gearing options too.

Use the same BT30 Spindle and go AC Servo. Anything over 1.5KW needs to be 3 Phase and is fairly expensive. £1500 probably for a 4KW AC Servo and Drive.

Might have to look at belt specifications to see if and how is possible. It must be HTD obviously as its made especially for that purpose.
