I recently purchased this same TS and the Bosch 1617 EVSPK router. Last weekend, I finished my "Router Table Insert", which was basically a piece of 3/4" shelving which I had laying around. Thus far, it is not bowing under the weight of the router, and the Gravity Lift seems very stable.
For the fence, I have just built a fence which is clamped to the saw's fence, so I can move it relatively easily and use the saws fence lock to lock it in place.
Since I am just getting started, I have tried to abide by the KISS rule since I have very little clue about what I am doing, so I do not know what features I even want to build into the parts yet.
Once I have my 10 posts, I will get some pictures taken and posted.
