Hi Andy the extension is from Trend. What make is your Router? How good are the head bearings? Any movement? My first router was a B&Q MCallister,seemed good value ,it was crap! bearings in head stock had too much free play and as a consequence would vibrate at high speed.
The other thing the Trend has is a very good Collet system. They are ground and with a very slow tapper that locks in to the collect housing. This is why the collect has to be fitted into the gland nut before fitting to the router. I also make sure the tapers and cutter bore on the Collet's are really clean.

My router is a Trend 11 (same as yours by the looks) The extension however is Record Power, supplied with the router table. It looks exactly the same as one in your pictures, so I thought you had the Record Power extension as well.
Is everyone happy with CMT extensions? At £27.50 from axminster it looks good value. The Trend one around £50 as is the Dakota from Rutlands (but tht has a 1/4" adapator as well).

Hi, Tell me why does one need a extention on a router as i wonder if a router was designed for one as in my view if one was using a large cutter or any other cutter come to that it would put more stress on the bearings and cause vibration with more pieces to come loose i would think twice about using one,
I would be interested to know why one would need an extention as i have not heard of them before,

Ivor, they're only used in table-mounted routers, often to compensate for the loss in depth of cut capacity when fixing the router to the underside of a plate of top. They can also be useful in those situations where your cutter is only 2 or 3mm short!
I certainly wouldn't like to use a larger raised panel cutter in one though. I think you're right with your concerns towards vibration...

|hi I've just modified my B&Q Pro router to increase the depth of plunge by half an inch by cutting down the body of the dust cover, which is the stop for the plunge. The collet now comes through most of the table plate and finishes almost flush with the surface of the table top. John Kinch.|

The main reason I use a extension in my table mounted router is because, when using a top mounted bearing profile cutter it doesn’t come through the table top sufficiently. However from the engineering point of view, if the spinning assembly is concentric, balanced and the bearings correctly designed , and assuming excessive pressure isn't placed on the cutter so as to cause it to deflect,there should be no problem with this type of assembly. But though I have never used a panel cutter, the length of the cutting face would apply large pressures on any router!
Regard all ,Nigel.

The only thing I'm sure about is this baby is not created to use it at full speed. My husband also tried it once, so that's why I know it. But if you already had some problems, it's better to replace it, because more problems will pop up with time (because I had some experience again). We solved it thanks to **LINK**, so you can go to check the source and find the most suitable replacement for you.
