I'm probably about to buy a Workbee 1000x750. I will be doing mostly 2 sided 3D carving in wood. I want a quiet spindle since my workshop is in the house and I anticipate some jobs taking several hours. My research so far indicates that a chinese 800w aircooled spindle with VFD would be a suitable thing to use. I notice that 1.5kw spindles are barely any more expensive, but I'm concerned about the weight. Most seem to use ER11 collets and a few use ER16 collets. Is ER11 a good choice? Is anyone else here using such a spindle? if so where from and how is it? Is there a particular manufacturer, specification or seller I should look for to purchase such a spindle? thanks! PS I'm in the UK.
