    Thanks Rowdy

    we tried the "soaking in vinegar" and then ensuring plenty of CRC lubricant first.

    then we tried your suggestion and it did loosed it and let it slide slightly on the collett however we slightly burred the end of the bit over and then had to cut the end off the bit. Then as we were trying to tap the bit back through the collett we actually plit the collett in two so end result was bit gone. collett gone but the big locking nut saved.

    However my good friend lent me his collett and I have been able to do the job I needed to do this weekednd so off to the Makita store on Monday to obtain a new Collett.



    thanks for your advice.



    regards

If I understand this right you can't remove the bit from the collet. If this is true there might be dirt on the collet and you can try and blow it out with compressed air. What I would do if that doesn't help is support the collet nut allowing the bit to hang free and gently tap on the back of the bit and this will remove it. It is possible that you may have overtightened it or the bit has a burr on it. Good luck

Aguired a black and decker model 7600 router tool. Did not come with instruction manual. I cannot determine how to change the bits.


They don't have an instruction manual online at the Black and Decker support site, but if you want a look at the exploded diagram, it's here.

Basically there's a collet nut that gets tightened down to hold the bit in place. You've got to loosen it up and you'll be able to pop bits in and out. You've got to have some way to lock the shaft while you're doing this though.

Most modern routers have a spring loaded shaft lock button. While you're holding it in, start turning the collet. When the shaft gets to the point where there's a little hole for the spring lock, you'll probably hear a little click, and the shaft will be locked so you can loosen the collet. If you take your finger off the shaft lock, it pops right back out again so hold it down while you're loosening and tightening.

If you don't see a shaft lock button, you may have a second hex nut at the base and with two wrenches, you can hold the hex nut and turn the collet loose that way.

If this answer was helpful, please give it a vote. Thanks.

How do i change the bit on router?


On my older Sears router there is a lever on the base near the collet nut that you slide to engage the motor shaft to lock the motor shaft for bit changes. On newer models you may have a button or different mechanism to lock the shaft. After the shaft is locked you can use a small wrench to loosen the collet nut, usually by turning it counter-clockwise (viewed from the base). Once the nut is loose the bit should slide out (sometimes the bit is stuck in the collet and the nut may need to come all the way off to get them apart). Just replace the bit with a new bit with the same shaft diameter, tighten the nut, and you are set. If the new bit has a different shaft diameter than the old bit you may need to change the collet also (in general, different collets are used with different bit shaft diameters).

Having difficulty seting bit depth


I'm not familiar with that brand, but no, normally you need only loosen the lock so the router can move up and down, and either twist it or plunge it into the correct position, lock it, check the depth, repeat.
If it's a plunge router you'll have a depth stop rod that you can use in conjunction with the stop nuts to dial in the correct height of the bit. If it's a conventional router you just have to twist it into the correct height and lock it in place without moving it.
If your router table is fairly light and portable, sometimes its easier to turn the whole thing upside down on a pair of sawhorses to adjust, then flip it back over. Otherwise, you just have to crouch down under there, aim a work light so you can see what you're doing, and adjust away.
Make sure you unplug it first!
Also be aware that you might need a fence for your work to ride against, that you may need to make your cut in successive passes rather than trying to hog off too much at once, and that even routers can grab the work and kick it, so be cautious and feed from right to left as you face the bit, (with the work closest to you).

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

I need help on how to replace bit on router craftsman style


You didn't state the model number. The older Craftsmen routers had a red lever lock on the top of the router, one position allows the spindle to turn, the other position locks the spindle. Here's the instruction for the older style routers:

  1. Unplug the tool.
  2. To lock the spindle press the red button in and slide it to the locked position.
  3. Unlock the height adjustment knob.
  4. Raise the router motor using the height adjustment collar until you can get a wrench onto the collet nut.
  5. Loosen the nut until it turns freely.
  6. The bit may still be locked in the spindle, tap it gently (not on the blade!).
  7. The bit will come loose in the spindle and can be removed.
  8. Replace the bit, tighten the nut snug but don't use excessive force.
  9. Unlock the spindle, returning the red lever/button to the free position.
  10. Adjust the height of the bit as you wish, then lock down the motor using the locking knob.

How do you fit 6mm collet cone on new produce


You have, I presume, already locked the spindle and loosened the collet nut with the wrench, have you not?
Once the nut is loose, you should be able to remove it by spinning it off the threads by hand. Then insert the 6 mm collet cone into the collet,
carefully thread the collet nut back onto the collet, and tighten it with the bit in place.
Sometimes bits are a snug fit, especially into a new collet. If you have some fin sandpaper you can gently chamfer the very end of the bit where you first insert it into the collet, and this may help to insert it. If you have to, push a bit.
I have noticed that some companies tend to mill the shafts of their bits a little too close to the exact tolerance, or even oversize them slightly, and this can cause frustration when inserting their bits. In exceptional circumstances, I have resorted to polishing a couple of small bit shafts with very fine (600 grit or so) emory cloth, just to allow the bit to enter the collet. I would not recommend this with a new router collet, unless you have checked the bit with a micrometer and it is oversize. Odds are you just need to break things in a little.
The force need not be brutish, but you may need to use some force, yes.
