I'm trying to setup slab flattening with my 1400. I've removed the bushing guide so I see how the router can fit up to a 63mm bit. That's great except it looks the dust extraction port won't fit on there with a larger bit like 1.5-2". In a perfect world I'd pick up a 2200. Too bad that I've already overbought other tools. A Makita I have works fine except it sprays chips a'plenty. Unless I'm missing something options are: get a small flattening bit, make a mess inside the shop, or pour a slab to use for outside flattening.
