Will, what model numbers are these routers? The new Craftsman combo's are not Bosch, just inexpensive copies of the design. I have never seen if confirmed but my guess is they are built by B&D or one of their companies.
From what I've read, some say the model's below are made by Bosch, or from what I've read at a few other websites. A quick Google search will show these. My smaller one is a 1-3/4 HP (I messed up earlier, and said 1-1/2), plunge router, model 27666, and they also have a 2 HP model using the same base, model 27683, and a 2-1/4 HP, model 27669 with digital speed control. The plunge base is almost identical to the Bosch, except for the above table adjustment, and depth stop rod.
Now whether they're made by Bosch, or not, I'm not sure. They could have licensed the design, and built these, as patents would be involved, and Craftsman couldn't have used it without it. My guess is that the same company is making parts for everybody, see below.
The 3 piece combo set I have, is a 2-1/4 HP, model 28084, and has the D-handle base. There's still a two piece like this they offer, the model 27680. Now, I'm not sure on this routers plunge base, but I believe it is not Bosch, but actually modeled after the new Rigid. It uses the same fixed base design as the others, or like Bosch.
The models I have do not use the rack and pinion height adjustment, but one similar to Bosch, that uses the notched motor for quick settings, and a screw type adjustment. However, the Bosch does not have a plunge base that is adjustable above table like its Craftsman cousin does.
Here's the thing on Craftsman power tools in particular. They're mostly made by the same factory that produces Milwaukee, Ryobi, Ridgid, AEG, Homelite, Hoover, Dirt Devil, and Vax. The companies name is Techtronic Industries, and they're located in Hong Kong. It is a possibility that Bosch may use the same factory for a parts source, and maybe design, I don't know. Anyhow, Techtronic generally just modifies one of the named tools above, changes it color, and calls it a Craftsman.
The router guide I mentioned is a Bosch, and it works well with my Craftsman routers, but only after changing the rod sizes to 5/16". I think there is another model that may have already had the smaller rods, just like it.
