fly cutter advice please

[Jonathan]

I clean it with the compressed air, or just wipe it. It's not too bad with aluminium though as the swarf is big chips and I've not cut wood for a long long time, except a quick bed surface.

Granted I do do it up tight, but it's rated for 30-60Nm depending on cutter size (30 for <=6mm) if I recall correctly ... been using a high quality collet lately too because I got it for next to nothing.

I may well take you up on the offer for nut, but it looks like I might have somehow killed the spindle anyway as you might have seen in my previous post. Why did yours break? Did you dismantle it out of interest? I know that's been done (CNCzone), but it would be interesting to see if the bearings vary.
