Whilst I’ve been told that the router chuck shown in the photograph has been around for quite some time, I have only recently become aware of it. Waiting for it to arrive reminded me of my childhood, waiting patiently for Christmas morning to arrive. Well guys, I wasn’t disappointed, This chuck has to be on a par with the invention of the PLUNGE router and SOFT START/VARIABLE SPEED. We can all now put those spanners into our general tool boxes, no longer being required to fit and remove bits from our routers. There are at present four versions of this MUSCLECHUCK and fortunately for me version #4 fits my main router, the Makita 3612C. It is an absolute pleasure to change bits using only a half turn of an Allen key. I received mine just in time for a BIG routing project (I’ll post a photo-shoot of it next week) and it performed perfectly, there is no way that a bit can come loose. I also got a 1/4” and 8mm reducer sleeve but when I changed from a 1/2” bit to a 1/4” one I forgot that I had the proper sleeve and wondered why I couldn’t fully tighten the bit. Once my mind got back into the right gear I used the MUSCLECHUCK sleeve and a half turn of the Allen key was all that was required.
I’m sure that members will have difficulty understanding why I’m going on like this, the reason is that routers are my favored tool and this invention is the future of routers. I defy anyone to buy one and not agree with me!

Wow, I haven’t seen this much excitement over a woodworking tool since the invention of a sharp edge. LOL Glad it made your day, nothing better than a happy woodworker. You should do a Review on this, the world needs more happy woodworkers.
Thanks for posting.

Great find…... I’m gonna have to look into one for my router… BTW, how much height do you lose, looks like about 1/2”?

Nice, but it cost as much as my router!

Seems like a good idea but $70 is half way there to a new PC router.

I forgot to mention that you GAIN one half inch of cutting depth. This chuck is, in my opinion, an essential item for anyone seriously interested in routing.
I’ve just dug out this website:

If one only uses the router occasionally and usually uses but one bit, then such a chuck probably couldn’t be justified, but as I’ve said, for serious routologists I reckon it’s a “must have” tool.

Thanks for that information. I too think you should list it as a review. Sorry to say I am not that good with a router and you may be the man that can help me out. Will be sending a private message with a few questions if you don’t mind.

Thanks for the post. I doubt that I would buy one, but I am glad you showed it to me. I just spent an hour on the Woodrat web site. It was interesting.

Thanks, Harry. with the arthritis in my hands I doubt that I always get the bits tight enough any more. I’ll have to look into this. Does it screw onto the threaded shaft of your router? I have a slick set up for my router station, but this could be good in my hand held router and plunge router. I’m a routerlogist by trade!

I don’t use a speed control so does it run out at high speed with that screw on one side like that?

..............Cheers, Jim

Jim, off comes the standard chuck and on goes the MUSCLECHUCK, believe me Jim, this really is the answer for us routologists with Arthritis in the fingers and something anyone using a router should save up for!
I have just completed a big routing job using this chuck and will post a photo-shoot next week. Tom, ask as many questions as you like. By the way, I have produced a series of tutorials “routing for beginners” I’m not sure if I’ve posted them on LJ but I’ll check tomorrow and add them if they aren’t already here.
