Just finished doing this. If you're cussing at the snap ring:

Put a flat head screwdriver under one side of the open part at the front (with the tiny holes), and push just enough to get a thin second flat head screwdriver under the back of the ring (you'll see a small gap as you start to pry at one side of the front of the ring).

Once you have that other screwdriver back there, keep enough pressure on it to remove the first screwdriver from the front of the ring. Then put the first screwdriver in the back gap as well. (You might need to push the second one slightly to widen the gap at the back but take it slow or it will slip out). You should now have two screwdrivers under the back of the snap ring.

Push one far enough under to get it showing on the other side of the ring. Now twist one of them. Viola! Off comes the ring.

Might take a few tries to get the one-to-two under the ring maneuver down, but it does come off easily no special tools required and not cutting of the plastic.

This is *exactly* how I finally got the snap ring off when doing this mod yesterday!

If you are also turning the spindle lock 90 degrees while removing the tool free attachment, be sure to also turn the black metal piece under the yellow plastic shroud. There are little pegs in the black piece that match with the shroud which I missed the first time.

This forum is awesome. Yes, i was cussing at the snap ring -- and then i got to that post. Then, i was just pondering the different alignment of the black piece underneath when i ran into Will Winder's next post...

you guys rock. Now, if only it wasn't 9:30pm and i could kick up some noise! This DW 660 is *loud*

IC

Thanks for the Mounts. I got them on Friday and put them on ASAP. I have cut a few things and I can tell a difference already. Now I must choose ...do I play or start upgrading?

Why is everyone removing the collet nut/lock? I can see people preferring a wrench, but I've found it very convenient so far. Am I missing something?

It makes for a little easier tool changes. IC made the observation (and I agree) that if handheld, the end lock twist is a great idea, but when you are dealing with the thing on the vertical, you are holding the bit with one hand keeping it from falling, one hand trying to turn the black knob thing, and one hand for locking the spindle. Now, not all of us grew up near three mile island, so not all of us have three appendages, thus... tightening with a wrench is easier. I have noticed that having the area cleared of extra stuff is kind of nice too.

There may be deeper ideas at play here too, but these were what I was aware of.

The thing with the 660 that I am trying to sort out is speed. I bought the speed controller linked somewhere in this thread. I also bought a little laser tachometer so I could get a pretty good read on how fast it is really going. Many forum threads talk about speeds around 10,000 rpm. When I try to go near this area, it just feels like it is loosing torque. I am still learning all the whines and moans of the machine, and now that I have been using hearing protection (something about not liking the ringing in the ears after a job) I have to get accustom to the sounds all muffled. But, It seems that it stays strong down to between 13,000 and 14,000 rpm.

You're also less likely to disturb the square and plumb of the machine if you're using wrenches rather than pushing on the device itself.

Thanks for the info, guys. I guess I must be the odd man out that has no trouble doing it with two hands. Then again, I haven't been changing tools a lot so it could be that I just haven't dealt with it enough to have the issues.

I'm also interested in variable speed. My next build is going to be based around the Beaglebone Black and BeBoPr++ and I'd really love to figure out how to use g-code to control spindle speed. I'm a ways from that and still getting the BeBoPr wired up and learning how to deal with LinuxCNC, but I'll get there eventually ;)

At this point you can also twist the insides 90 degrees to put the shaft lock on the side with the DeWALT logo.
I like this mode. I tried to re-assemble with the button on the same side as the logo like you did, but there are a couple molded plastic pins that prevented me from rotating the cover 90 degrees. Did you cut these pins off?

Do you mean the black pointy bits (one is big and the other is small)?

If so, if I recall, you can turn the whole square, essentially changing the direction of the electrics, and align this up with the bottom as it was designed to be connected back together.
