I'm going to use a 2.2kw water cooled spindle. Any ideas on a cheap, closed loop cooling system? Also, anyone tried the "Sanven" spindles on amazon.co.uk?
I think this is the least of your worries as the spindle will only need about 2-3 litres of water in a tank to keep it cool.
Don't buy anything until you have put some sketches on here and had feed back from the very knowledgeable people on here and take the criticism in the spirit it which it is intended.
Good luck with your build. ...clive
