Mike- the first question is what router are you going to use? Go with a big one like the 3 1/4 hp PC 7518 (the quasi standard)or PC 7539 (plunge), or other big, hefty,
VARIABLE SPEED* router. * You may end up swinging some relatively large diam. panel raising bits and you will need to slow your router down.
Selected thoughts (pics and more details of everything upon request):
Which version? Are you building the new or old version of the NYW table? Actually, I liked some features of the older version, so I made a hybrid.
Table top- If you make your own use 2 layers of 3/4" MDF or one each of 3/4" and 1/2". Put laminate on both top and bottom suraces. They works like beam box skins to give the top more rigidity and to seal both surfaces.
Miter slot- the need for one is subject to debate. You can register sleds against the fence for just about any work (cope & stick rail ends) needing a miter slot. horizontal feather boards can be clamped to the table overhang. Unless properly supported a slot can weaken the table top.
Dust collection- personal preference, I don't like the hose running out of the back of the fence and the wye fitting hanging out of the back of the cabinet in the new NYW table, so I used the through-table fence dust port of the old NYW table. I also added angled baffles inside the cabinet to channel the dust to the DC port and prevent dust collecting in the corners. Run a minimum of 4" DC line to the router table
Fence- I will be upgrading my old style fence- making it a little higher, laminating the face, installing a feather board T-track like the newer NYW table. I also want to add a micro-adjust feature - the fence will slide or pivot on one side and micro adjust slide on the other. I really don't like Pat Warner's and the other micro-adjust fences I've seen so far.
Router lift- a must! All those mentioned here are good. Since I have a PC 7539 plunge router, I went with
Wood Pecker's Plunge Lift. One negative about using a plunge router is that I had to rig a cable to release the router's plunge lock- I initially permanently rigged the router's plunge lock lever in the unlocked position, but found the Plunge Lift lead screw would slowly rotate and the router height would decrease from vibration. Though the need to do this is up for debate, I removed the plunge springs from the router. My Plunge Lift has the 32 tpi lead screw- it takes a lot of cranking to raise that sucker up high enough to change bits. See my solution next:
Power-lift- I added a coupling and shaft extension to the bottom of the Plunge Lift lead screw, ran that to a cheap
HF right angle chuck then to a cheap drill. I wired the drill to a panel paddle switch and can now quickly and easily raise and lower my router by pushing a switch.
Mobility- I added two fixed
casters from Hartville Tool (great BB casters at a great price) under one side of the cabinet (I removed the original axle and bracket and mounted the wheels directly to the cabinet with a bolt) and a
Rockler (Delta style) step caster to the other side to make my router table mobile.
