Yes; after the dissapointing discovery I pushed the springs with rubber surrounding down on both pillars. I can say they are thin for sure. The surface on the left pillar is polished and there is no gap between the pillar and the case. It's made as it should be. But the right pillar is black and has rough surface and there is substantial gap between the pillar and the case. As a mechanical engineer I don't know what to think. After all, they are Bosch and they suppose to know what they are doing. My friend has pof1200 and he has the same problem. Apparently my router is not just a one case of foulty product. It's a design fault. Oh, lucky me. If I send the router to service I can bet they'll say that's nothing they can do and it's made that way.
Makita, Metabo and DeWalt routers were just to expensive for my needs. Not that I could not afford them, I just didn't want to spend so much on a router. If I put aside that flaw I must say that I like this machine. It has a soft start, fine depth adjustment, prm regulation,constant power electronics, two leds to enlight the working area and the motor is not loud. I guess I'll bite the bullet and modify the thing by myself.
