I also recommend one goes to their local hardware store, buys a 7/16" (or 1/2") rubber o-ring. Drop it in the collet hole. Then, when you insert the bit, it rests on the o-ring and when you tighten the collet, the o-ring compresses - keeping the bit from bottoming out. Been using that technique for years in a couple of my routers. Works well.

I insert the shank into router collet until it "bottoms out" (won't go in any further). I then lift it back up in the collet about 1/8 to 1/4 inch. Have never had one get stuck and never had one come loose either! There is/are one or two router bit manufacturers that do put a line /mark on the shank where they recommend you insert the shank into the collet to that mark.

Same with the Router extension. Kind Regards, Timothy J.

Then when we tighten it, it will bury out and tighten up as a jamming to the bottom instead of squeeze onto the bit or extender shaft. So in this condition, without enough compression on the shaft, it will only take a little vibration to get everything loose enough to start slipping. Good thing for us, there is usually a lot of vibration noise or our work that gets in the way of launching it at us. The solution is; figure out how far you can insert the shaft and get a measurement. Then remove the collet and see how far in the shaft will run into the collet before it pops out the other end. Now if you add 1/8" to the collet measurement and subtract 1/4" from the depth measurement, you will have your safe install zone. On my carriage, I made those 2 marks, scratched into the metal. It's pretty easy to make an ink mark on the router bit to make sure you are in the safe area. Now install it and while running, you may lose the marks but you will never lose the bit! Now there is one more thing you need to do. Your extreme shaft may have suffered some damage. Make sure the shaft is smooth and free of burrs. If you need to polish it, you can chuck in a 1/2" shaft into the drill press and the chuck the extreme onto the shaft as well. you will now be able to spin the shaft and work out any imperfections the slip may have caused. Good luck and be safe. Mike OK On 6/20/2023 8:10 PM, Mike Newman wrote: I have a question for those of you that have the extreme router bit extension on their LOM router. How often do you check and re-tighten the extension into the router? I have had it come loose a couple of times with no real advance notice. Do you check it every time you use the router or so much run time between checks? Ruin the walking stick I was working on but no issues with the router or collett/nut that I can see/feel. -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
