There was a discussion here a couple of weeks back of the problem of holding all those little parts in place while reassembling. Todd Hughes, I believe it was, recommended just finding another chuck, which has been my (limited) experience as well. Unless you've got two extra hands and fingers of small-diameter spring steel, I'm not sure it can be done in the home shop.

Toss it

>Carl,

I have fooled and fooled and fooled with trying to get these chucks back together and it is hopeless. I'm thinking that a special tool was used at the factory to assemle them. Maybe if your so inclined you can re-invent the special tool and probably make a small fortune.

to answer your question tho, on top of the chuck there is a slot and if you can find something thin enough to fit it, and it's not rusted together it should unscrew. I've been told that the back of a saw will do it, but don't use a good saw, use one that is only suitable to be used a scraper material.

Save your self some frief and toss it, unless it has some sort of sentimental value, than just find a replacement. that's what great-grampa would of done I bet.

>Hi Carl,

If, despite all the recommendations that you just throw it out, you still want to take it apart - check to make sure there's not a set screw on the side locking the inner and outer pieces together.

Carl, if you like tinkering, go ahead and disassemble it; if your goal is to make things from wood, trash the chuck and find another.

>Looking at an old Stanley catalog, they show a screw inside that's exposed when you open the jaws wide open. But it also states that the base and shell are "staked" together. That means for complete disassembly, you may have to break it. Yours obviously may or may not resemble a stanley.

>Just to bring the subject up to date.

After soaking the chuck in mineral spirits over night, and applying sufficient torque, the cap broke loose, revealing the plunger and jaws, the springs being extracted earlier from the other end. After cleaning, I applied a drop of super glue to the spring ends before inserting them into the holes in the jaws. Placing the jaw/spring assembly , points up, on the bench, I slipped the chuck cone over all. Once inside the cone, I inverted all and replaced the plunger. Working from the bit end, with a pair of tweezers, I made the final adjustments to the springs, and screwed the whole thing back on the arbor. Operation sucessful, patient recovering nicely.

Very clever indeed

>The superglue is a very good touch - strong enough to hold the springs in place, weak enough not to interfere with operation.

So it can be done!

>This sort of reminds me of when I used to race bicycles, and would take the freewheel apart for cleaning. had to hold the pawls closed with dental floss, hold all the bearings in place with fine lubricant and assemble the halves with a steady hand. After both halves mated properly, I would just gently pull the dental floss out. Easy peazy and Bob's your uncle.

>Well by goodness Carl, I'd say that you've cracked it!! GOOD ON YA!! Another, "why didn't I think of that" Just goes to show that what is considered "impossible" isn't.

Now I've got to rummage around and see if I still have any of those boogered up chucks.
