I've been playing with the new 310 since a little before Christmas. I got frustrated with the sticky collet and tried a little teflon grease on the *outside* only of the collet. I couldn't tell if the bit was sticking in the collet or the collet in the shaft. It really worked! No sticking at all. I was concerned about the grease attracting dust but it didn't seem to happen much through many bit changes. On part of a current project (yes, still the arbor) I had to change bits 3 times per piece due to contours and templates. And there are 8 of these pieces. And many experimental cuts so lots of changes in one evening. All went slick.
I was still frustrated with the adjusting ring being sticky when using one hand to hold a square over the bit for depth setting while holding the router and adjusting with the other hand. It's not as bad as it sounds, but I needed that ring to be free and you could feel the aluminum to aluminum drag. Last night I decided to either wax the housing or TopCote it. TopCote was easier. I pulled the collet and cleaned it and the hollow in the shaft and shot a little TopCote in there wiping out the excess. Shot the body. Boy, what a difference that made! Smooth as silk now and the collet is still not sticking.
I know I was taking a chance on a bit slipping so I ran a couple of old cheap roundovers on some utility shelves around the shop. Nothing slipped.
This little honey is a real jewel. I am grabbing it for jobs that I probably should use the Dewalt 621 on. But it is so light and handy in comparison that I use it anyway. One handed routing is nice. I do moderate the cuts to the trimmer's level but even then I think it may be as fast as the big router on lots of small bits and small jobs. Now for a clear base, maybe Pat Warner's, and to get rid of that housing knob for a lever.
Thanks for the recommendations and helping me decide on a model. It's my first fixed base router and it's not as much of a handicap as I thought.
