Question Sticky collet

I have owned my Makita M12 /3.5hp plunge router for 7 or more years, and like its power and ease of plunge height adjustment. Mine is mounted in a Veritas (Lee Valley) steel surface router table. It has a home-made crank for height adjustment, and while only a single-speed model, works well through a plug-in speed controller. The only real complaint I have is that the bit is difficult to remove after use. The nut is not over-tightened, and the collet and inside shaft are rust-free, but sometimes it requires loosening the nut entirely then tapping the bit and collet with a piece of hardwood and a mallet. I've also tried using a bronze-phosphor brush to clean inside the shaft; used 800 or 1000 grit wet and dry paper to polish; ensured that there are no burs on the bit shank; even put a drop of light oil on the bit shank prior to insertion. Yet the same damned problem remains. Any solutions out there? (And no, I'm not going to replace the router).

Welcome to the forum Jerry.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Jerry, Some collet nuts are heavier (more mass) than others. If the router is turned on the nut will tighten down by centrifical force and if there is no bit installed, it could damage the collet permanantly.

Hello Jerry,
I went through this same exact problem with the exception of it happening on a Milwaukee router. It got so frustrating that I bought a new collet and still had the same problem and ended up shelving the router for a while. After rereading some info here about the Musclechuck I replaced the Milwaukee collet with a Musclechuck and it has worked flawlessly and so easy to change bits. I ended up buying two more Musclechuck collets for the table routers.
