I weakened and bought a cheaper router than I should have, thinking to fit it to a pin router frame I'm making. I know I shouldn't have, so don't lecture me. It's a 1600W type with 1/2" and 1/4" collets, rebranded Ozito from an Asian mfgr (sold in Australia).
Anyhow, when I unpacked it and fitted a bit to the 1/2" collet, I thought it seemed not to want to remain eccentric as the collet was tightened. After 5 or 6 goes, measuring the eccentricity with a digital vernier, I couldn't get it less than 0.4mm...!!! unbelievable... it's all packed up in the box unused, ready to go back to the shop tomorrow or the next day.
What's the point of using a collet chuck if not to get a perfectly tight concentric grip? I mean, if I want a 5mm slot, and I get one that's 5.2 *at best*, the tool is simply not of merchantable quality - and that's exactly what I'm going to tell them... sigh. Occasional satisfaction with a cheap brand has made me careless :-).
Does anyone want to tell me there's a ready source of quality collets that might fit this otherwise well-featured machine?
