I have the two from MLCS and use them all the time,but like you now and then one of the bits will get stuck,,
I made a small pair of hardwood tools to get around this error...
it's just some 1/4" thick hardwood with a slot for the shank to slide into the slot , the wedge pair,,,, it's best to use two ( pair) you just slide one on and then tap the other one and the bit just comes right out easy..
The wedge looks like ball joint splitter only smaller..
I also use the 1/2" one most of the time with a 1/4" adapter that's keep the 1/4" bits from sticking..I got the adapter from MLCS also.
I also have the Xtreme Xtension and I don't use it,,because of the vibration.
I plan to design and build a new router table this summer after I finish off my current project (a couple of planters for the wife). The new table will probably be along the lines of an enclosed cabinet (I need the storage).
As such, I want to be able to adjust the bit height above the table and also to be able to change bits topside. One other constraint is that I am college poor with a daughter in her last year, so cost is a concern. My router is a DW625 and I have thus far used a homegrown lift that only works under the table. So for the lift I am pretty much sold on the Router Raizer for the following reasons:
1) It is cost effective - $90 on Amazon
2) I like the idea of being able to use the lift in or out of the table
3) It can work with any table/insert
4) It got overwhelmingly positive reviews on Amazon
Unless someone can show me another alternative that I have missed that meets or beats these criteria I think I have resolved that decision.
Where I am struggling is with the above the table bit changing. The DW625 is height challenged, especially with some of the 1/4" shanks. I have the MLCS collet extenders and they work great, but I have a couple of issues with them. Especially with the 1/4" extender, the bits tend to get stuck and I almost always have to resort to using tools to get them out. I fear I will ruins some bits along the way with this. It is too tedious and time consuming. Also these extender require two wrenches to loosen and tighten the collet, not a big deal, but somewhat annoying.
I have looked at the Xtreme Xtension which is designed by the same fellow who did the Router Raizer. It uses a single hex wrench to make bit changes which I like. I have read of some potential vibration problems with this extender, but the instructions give pretty detailed steps in how to minimize this and reduce runout.
So what am I asking? Any tips on using the MLCS collet extenders? What do you think of the Xtreme Xtension? Any other collet extenders I should consider? Thanks in advance!
