Morning all. I am cursed with the owner ship of an older style Craftsman router.

It has the very annoying habit of changing it’s cutter depth at will. IE If I’m cutting a 1/2 X 3/8 deep rabbet the cutter will drift down to almost 1/2” deep. Am I trying to take off to much material at once? Or should I make 2 passes per rabbet? If not is there a solution to the tools problem? A new machine is not really in the cards at this time. Thanks.

Most likely the collet is worn out, although I would be hesitant to take that much of a cut in a single pass with that router as well. Do an online search for that model number and see if you can find another collet insert. You might also look at ebay to see if you can find one.

Is that the one with a bolt in the back to “lock”it it place? Is there a wing nut on that bolt? If so, add a washer under the wing nut. And maybe make a lock washer. Vibrations are working the bolt loose just enough for the mototr to slide down a hair.

Could use a photo of the back side. Been a while since I’ve seen that model.

Classic symptoms of a worn out collet.

I had a BnD router once that I was unfortunate to own.
That is, until I realized the trash pickup comes every Thursday in my neighborhood.
That seemed to solve the problem.

Love my PC690 and DeWalt 3hp plunge routers.

Yeh, buy a new collet, or, perhaps a new router – whichever is less.

If you can find a way to do it, Rockler has a PC 690LR and a laminate trimmer for $155. The router you have now will be hard to find parts for and really isn’t worth spending a lot on finding parts.

It could also be your bit is worn. My Ridgid router suffers from depth wander when the blade drags in the wood. Time to change the bit at that point. Even a new, good collet can’t fight through the drag of a dull blade everytime.

Take the collet nut off and remove the collet.

Then you’ll have 3 parts and you want to brass brush
them. I use a plumbers flux brush to get inside
the router shaft but 400 grit wet/dry paper on
your finger tip works. Just get the rust out.

Then you want to work the outside of the collet
with a brass brush or 400 grit paper. Get it smooth.

Then the inside of the collet. It’s 1/4” so I wrap
a strip of paper into a tube and run it in and out
while rotating.

Finally, check your bit shank and clean off burrs
if you find any.

Then try some test cuts.

Your collet should be tightened down “with a fair grunt”.

Those have the “collett” as part of the end of the shaft. I had the 1hp version, a long time ago. Just a collett nut. The only trouble i had with it was the shaft lock bar broke in two. Made it hard to change the bits. Place a lock washer ( about $.39 @ Lowes/HD/ACE) under the wingnut that locks the depth setting in place. Seems that your base is a little worn where it touches the motor housing. Use at least one washer, and a lock washer, and the base should tighten right back up. Money saved from doing this, and a little extra down the road, and you could afford one of these.

Much improved over the years…

I have that router too, it’s in semi retirement. The collet is the end of the shaft and can’t be removed w/o taking the motor apart. I am willing to bet that it is not the collet that is slipping but the depth setting wing nut. I recommend taking it apart and give a thorough cleaning and then roughing up the motor housing, the part that slides in and out of the base, w/ 180 sandpaper. That helps the base grip better when the wing nut is tightened.

I wore the bearings out on mine, by hanging it in a router table. Not recommended! It took a few years, but the bearings finally went out. had a problem with the depth settings, until I added those washers. Tighten right up.

These routers are notorious for collet and depth stop failures.

I once took a Virago into a motorcycle shop and asked what I could do to make it faster.
The salesman replied “Buy a Ninja.”

I think that’s where you are at now. The ninja is a Dewalt 618.

Pinto. I had a Virago for almost 5 years. Not a screamer, but bullet proof.

I hope you have a better router in your future. I had a C’man like yours years ago. The main issue I have with them is the 1/4” capacity collet. Half inch shank bits are so much superior. I never use a 1/4” shank bit unless I have no other choice.

Have you considered used? Porter Cable, Dewalt, Bosch all appear on CL from time to time. You’ll be a much happier woodworker.

Mark: Seems to be just what I need, no issues that I have found with it. I got the fixed and the plunge base as a kit last year. It will use both the 1/4” and the 1/2” shanked bits. Lots of good features to it. When you get a little time, go check one out.
