I'm puzzled too. I have the Trend Pro router table and Trend Router.
From what I can see the principle of raising and lowering the router is exactly the same as if I had a lift fitted to to my table.
My Trend Pro has a hole drilled in the top for placing the adjuster in so you can raise and lower the Router for what ever purpose, from the top. The lifts use the same principle.
If my understanding is correct, and to save a lot of money, all this gent has to do is get a suitably sized hole drilled in the router fixing plate. He can then use the T11 adjuster as it was designed to do; from the top. This would also get his router to a height that he can change bits as the router plate is around 10mm (My Pro table is 8mm thick so roughly the same). Be aware some lifts plates and router table plates, whrn combined, can be well over 10mm, meaning you might then have to have a collet extension for certain working applications (something to avoid if possible).
It would be good to hear back from the gent who raised this question as I hope we've all understood correctly.
