Please see thread: http://www.routerforums.com/table-mo...uter-lift.html
Contrary to Hilton’s comments:
1. Hilton appears to be overlooking a salient point with shop-made lifts - one doesn’t need the router base. One can mount the motor unit in the lift, as done in the ShopNotes one or my design. So, no plunge base and no fixed base required.
2. You do not need a plate to house the removable inserts. I used the Incra inserts and some magnets. Works a charm – no screwing or fiddling. Drop in and pop out.
3. With my design (but not with the ShopNotes), a lever engages/disengages the threaded rod, allowing the user to raise/lower the router quickly. This is particularly useful for bit changes.
4. I challenge the statement that a plate is more secure. Whether one goes with the ShopNotes one or something along the idea I used or a combination, the router motor is securely mounted.
5. With my design, the lift is mounted to the cabinet, not the top. Consequently, the force on the mounting bolts is lateral to the bolts, and not trying to pull the bolt out of the wood. Also, the weight of the router and lift is borne by the cabinet, not the top.

If you want to do it the hard way, use a router that needs lifting through the table to change bits. If you're prepared to emerge from the Stateside way of thinking, then invest in a plunge router that allows above table bit changes and subsequently no fiddly lift is required.
Contrary to what Cassandra said (but not totally), you also need a router plate to house removable inserts. These are necessary of you want zero clearance around the bit for a cleaner cut. You could just make your own set of plates with various hole dimensions but then you would be unscrewing the router every time.
Even with a fixed base router with a lift, you would still need removable inserts unless of course your router is set-up to perform only one type of cut and the hole is sized appropriately.
Last but not least, a plate offers you a more secure way of attaching the router. If you just screw it to the table, you would need to think about threaded inserts or something more substantial than just a few wood screws holding your router upside down.
Hope this helps.
