I bought a 747 mill late last year. It's been working like a charm for drilling and milling with my 1/2" mill and collet. I needed to mill a 1/4" slot in something over the weekend, so I pulled out my 1/4" collet and end mill to put in the machine. However, I was unable to tighten the collet down inside of the spindle. I thought this to be very weird, as the r8 taper for the drill chuck and my 1/2" collet worked with no problems at all. So I started inspecting and found that the spindle has no keyway for the collet to slide into. Is this common? Why does the 1/2" collect fit and able to fully tighten down, but the 1/4" collet doesn't go all the way in (about an 1/8" from going all the way up into the shaft) and it won't tighten down at all. The drawbar just keeps on spinning. I bought a collet kit, so they are all from the same maker. Any help will be greatly appreciated. And please pardon me if I am not very clear or say "the wrong things." I am not a machinist or anything like that. I am a hobby knifemaker who happens to own a mill, which I'm still learning about.
Thanks,
Seth
