DW616 vibration/noise on spin down?

[Mark Rios]

WHEW!!!....have I been busy. I'm finally able to see some daylight. I'm finishing up a couple of odds and ends for a couple of projects before starting a complete kitchen remodel.

On one of these odds and ends allowed me to finally get to use the reman DW616 that I bought a few weeks back (from Tyler Tools). After finishing the first pass I turned it off and let the router hang down in my hand while it spun down. I noticed at two separate times (speed ranges) during the spin down that there was a noticeable change in pitch and a small vibration. These each lasted approximately 1 to 1 1/2 seconds. It continues to do this every time I turn it off. I was using a 1/4" roundover bit. I only ran it for about 12 feet in a total of 4 passes. There is no noticeable/abnormal noise or vibration while it is in use that I can tell. I can't feel any movement iin any direction while moving the arbor by hand.

Is this anything that I should be concerned about? Is this maybe just some sort of bearing noise/vibration that is normal or to be expected or is this something that I should call Tyler Tools about?

Thanks very much for your advice and opinions.

Does it happen with no bit in the collet? Remember to tighten down the nut after you take the bit out and before you test.

Or try another bit. Perhaps your RO bit is a bit unbalanced! :)

Sorry, I forgot to include that part.

Yes, I tried it with two other bits, another (Oldham, I think. It's yellow) 1/4" RO and a Freud 3/8 RO, as well as running it with no collet at all. Same thing each and every time.

"Same thing each and every time."

With that statement, you've narrowed it to the armature bearings, typical of a well used tool.
I have a lot of routers, the only ones that do that are the old & tired. I would still expect a couple more hundred hours, but it will need bearings soon if your primary kitchen router is this one.

Thanks very much Pat. That's the kind of experience that I needed. As I mentioned, this is a brand new "Reman" from Tyler Tools. I guess I'll be calling them up and asking for a replacement.

Thanks again very much to all.
