This is a first for me with newsgroups and I don't know if
it is alright to put a question about my router.
I bought a Craftsman Prosessional Plunge Router (Model No
315.248870) in July 2002. I used it two to three times at the
most. Last time that I used it ( yeasterday afternoon), sparks
and/or arc was showing through the vent slots. Not wanting
to do damage to it, I stop it immediately. Since it is monted
on a router table I reached under and touched the router body
to see if it as hot. It was cold and I tought so since I only done
about two feet of edging on a soft piece of spruce. So, I hit
the triger but to my dismay it would not go. I checked the plug
and the fuse box to no avail.
This morning I took the souter off the table and as I handled
it some thing seemed to giggle inside the casing. I turned it
right side up and then upside down hoping what ever was
loose would come out. All I got was some small black pieces
of what the motor brushes are made of. Upon investigating
the brushes, one of them had broke in half.
I opened the casing hoping to retreived the broken particle of
the the brush before inserting a new one. To my supprise I
found three or four small pieces of the stater all chewed up.
Needless to say I am returning this router for service. Has
any of you had a similar experience? What could have caused
the brush to desintergrate? What did I do wrong? This router
is brand spanking new. What gives?
I have a friend that had a similar experience with a Craftsman router,
although I don't think it was the same model. He found that pieces of
debris had fallen into the vent ports while mounted in the table. When
the router was later started the debris tore the windings apart.

Not entirely unusual for an armature commutator failure in a relatively new
motor. It is made from thick brass pieces that develop a good amount of
outward directed weight as it spins. They depend upon non metallic
insulating materials to hold them in place and any defect will cause a quick
failure as they are first subjected to some heat and high speeds. If they
pull apart even slightly, They will break the brushes.
Sears' motto is 'Satisfaction guaranteed, or your money back.' I would do
that rather than wait for a warrantee repair. Take it to the Sears' service
He's already too late. They only guarantee their power tools for one year!
Already been through this with 2HP fixed base Crapsman, over 1yr. old, less
than 1hr. total time, main bearing heated up, heat loosened plastic cooling
fan on shaft, it walked up the shaft & ate up the stator winding. Ended up
ordering new stator & bearing & fixed it myself.
The first myth of management is that management exists.
I have a sears router, got it about the same time. The plastic thing in the
top to lock the shaft to allow the bits to be changed sticks so I have to
lay the router on its side and smack it with my palm to get it to slide. I
took the router apart and cleaned it out but it didn't help, I didn't see
anything worn or broken. Making my first cabinet I found out all the slots
for shelves were varying depths because the plunge lock doesn't hold tight
enough. I've had it lift up and plunge down going all the way through the
wood and ruining it. I had a 1/4" spiral upcut bit come out of the collet
once, it started to feel funny and I released the trigger just in time.
The router bits I bought to go with it got dull the first use.
I still like Craftsman hand tool. I have bought plenty of wrenches,
sockets, etc, broke one or two and they replace them with no problem. My
sears Dishwasher and stove and microwave are great. Sears power tool, I
won't buy anymore. I have made good friends with a couple employees at the
sears in the new mall near where I work, my salery being doubled two years
ago has helped my to buy a lot more tools and they know me well. So I get
to mention from time to time how I wish I could buy a new table saw, drill
press, lathe, etc if they would bring back the quality. Hopefully the
message will work its way back up the chain.
Old Salty Frog thought it a good use of my time to say:
Used to work in Sears Hardware(~14-15 years ago). They then had just gone
back to making the Craftsman(badged) hand(mechanics) tools in America. Had
a guy come in with a 60 quart ice chest full of broken tools. He dumped
them on the floor and left!
The Sears badged tools are China/Japan/Honduras/whatever.
Power tools are a different story-small hand(dremel-type) tools were made by
Ryobi/B&D. Larger(drills, router, etc) were B&D. Table top saws/drill
presses were Delta. 1 Year warranty on all tailed stuff. After that, "We
can sell you a new one, and a Maintenance Agreement to go with it"
BTW, The Kenmore line is made by their "suppliers", as well. Maytag,
Whirlpool, Hotpoint, etc
Thanks to many of you did answer my question
and I am very greatful and endebted to you.
Your answers were must appreciated and I will take
my router back to Sears and obtain a replacement. Try
to get a replacement although it is still on the waranty.
Sears my just want to service it - this is also OK by me.
Gee - I don't know about you guys - I have a Sears 1/4" router all aluminum
body, pistol grip handles circa 1963 that has held together perfectly for
over 40 years. Guess they don't make 'em like they used to. Think I still
have the manual that shows the PROPER way to cut is against the rotation of
the bit - a climb cut.
If it is rotating clockwise and the cut you are describing is:
In machining it is not a climb cut. In machining, with a cutter going
clockwise, a climb cut is:
And that is not the way the manual on the new router I got says to use it.
