I have never used a fixed base router. Fixed base routers are not big here and never have been, they look awkward to me for depth adj. and bit change, and don’t have as good a view of the cutter. You could say I’m suspicious of them. Or am I wrong?, what is it about a fixed base router that makes it better than a plunge router? They certainly seem popular amongst LJ’s on the left side of the Atlantic.

Ease of depth adjustment compared to the plunge base. Same goes for table use if you don’t have the top type adjustment.

Well, they are cheap in the states and used ones are common.
Professionals sometimes own dozens and leave most of them
set up permanently for one cut depth.

They also have a lower center of gravity than most plunge
routers so they are less tippy in poorly supported cuts.
The handles on the base and the way you can wrap your
hand around the base at the bottom is nice too.
I often wedge my hand in between the handle and
the base. Plunge routers have less to hang onto down
low.

Have no idea, I have 4 routers, two of each and a cheap Harbor Frieght laminate trimmer for those quick trim jobs. One plunge router is mounted to the table, the others are freehand. In looking at my Dewalt pluge router it is much larger than the fixed base and admittably with my wrist issue weight is a factor.

Is it possible to plunge then for stopped dadoes? What sort of depth of cut can you get from a FB?

You can usually get them to adjust so the front of the
collet nut is at least flush with the sub-base I think…
so from there it’s your cutter that defines the depth.

Depth varies from design to design. Some of the newer
ones are designed for router table use (Milwaukee,
etc.).

You can plunge them by adjusting the depth while
holding the router steady, but it can be a little wiggly,
again depending on how the router is designed. Shallow
plunge cuts can be made by holding the router at an
angle on one edge and lowering it by hand. Old
woodworking magazine articles describe mortising this
was. The first plungers available in the states were
probably Makita in the late 70s or so. Pros who had
never even heard of a European slot mortiser snapped
them up and marveled at their mortising power…

European machines were barely available in the USA
before 1980 and obviously European design trends
are different from classic American iron.

I use FB almost exclusively. Depth adjustment (Porter Cable style with the moveable ring and spiral grooves) is very easy and quite precise. Field of view is good as I swap out bases with larger holes when needed. One thing I much prefer over plunge style is that the FB (being enclosed in a full body ring enclosure) is more accurate on the true 90 degree relation to the work. I find most plunge styles rather wobbly on the two smallish guide rods and as mentioned the centre of gravity and handles are much too high. I don’t do stopped dadoes, nobody tells me when to stop. If you do get a FB, get a D handle type – they are supreme.

I have the Bosch MV23 combo router. I used the plunge base for edge work, but like most folks have already mentioned its not very stable. I was getting disappointed in my router for the simple edge jobs. Then I unscrewed the fixed base from the table and gave it a shot.

Much, much better. Easier to control and more stable for sure. Setting depth is pretty easy, too.

Definately worth doing. I didn’t think it was that big a deal just reading about it on forums, but now I’ve seen it for myself.

I have two fixed bases mounted under two different router table tops. I use the plunge base for hand held operations.

I have a plunge router mounted to a table, but I’ve recently removed the springs. Much easier to deal with depth adjustments now.

Well, my first router was fixed base because in 1970 I don’t think they had invented the plunge base routers yet.

Fixed base routers have less inherent slop.

I don’t grab a plunge router lest I have to use one.I use router every day and don’t like the top heavy plungers.

I bought a combo fixed/plunge based Ridgid router and put the fixed base in my horizontal mortiser and saved the plunge base for hand work. Never looked back.

If your using a dovetail jig I’m a guessing you want to stick with a fixed base!
