Default Plunge router question

Hi !
I am a new member on this forum and I'm a begginer in woodworking. A couple of weeks ago I've bought myself a Bosch pof1400ace plunge router. Since I'm a begginer and this is my first router I'm still toying around and discovering things, that could be done with this machine. The router is nice; it has a soft start, fine adjustment of depht (0.1mm step), plenty of power for my needs (I guess) and It's not so loud. The cuts I've made are nice and clean and the surface finish is smooth.
But there is one thing that is bothering me. The locking mechanism locks only the shaft on the left. The right shaft is able to move slightly under downward pressure. If I look closely and press on the right handle I can see the router bit moves left a few degrees and it's no more perpendicular to the surface I'm routing. A few days ago when shopping I examined a few other routers (B&D KW900 and Bosch pof1200, Einhell-something) and all had the same thing.
Still, I need to ask you if you have any experiences about this case.
Thanks a lot for the answer.

All plunge routers just lock on the one pillar. However, the pillars are normally sufficiently rigid that I've never known it to be a problem in normal use. You'd need to apply a lot of force normally to the 'slave' pillar to get it to do as you describe.
I've DW, Ryobi and Einhell routers and never encountered this problem.

BTW, whereabouts are you? from the mention of Einhell, I'm assuming you are this side of the pond.

Cheers

Peter

Thanks a lot for the answer. You are correct; I'm from this side too - from Slovenia to be exact.
Your answer made me worry that I've chosen a bad router. I found on the net the same issue with another Bosch router 1613AEVS. Here are the owners words: On further examination and several more attempts I noted that the plunge lock really locked only one shaft. The other was able to move ever so slightly under downward pressure on the handles. The result, of course was that where more pressure was applied the cut was deeper. Maybe only .05″ or so but enough to be noticeable, especially in a dovetail.The router in my evaluation was not up to professional standards.
The exactly the same thing is happening with my router and exactly the same problem had the Bosch pof1200 router in the store.
Here are the words of another owner of Bosch 1613AEVS: The plunging action was fine except that the bit will move off of perpendicular due to lack of rigidity in the plunge mechanism and the rods the router moves on.
Apparently this is a common problem with some Bosch models so be aware when buying.
Regards;

I bought a new 1/2" variable speed Bosch router some years ago for use under my table. I soon found that applying pressure tilted the cutter slightly towards the fence. This surprised me because the two pillars looked to be ginormous, that is until I lifted the rubber boots to find disappointingly thin pillars. I shimmed the router to lean forward to compensate and this worked in a fashion until I discovered MAKITA routers, what a difference!

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.

I've an idea that some Bosch domestic products are actually made for them in Slovenia,although not their routers. I've Elu stuff too, that was made in Slovenia.

Whereabouts in Slovenia are you ?

Cheers

Hi Peter;
I know for a fact that some of the Bosch washing machines are made on the production line in Gorenje factory.
This particulary router I own was made in PRC and I think I can't blaim the chinese for the flaw this router has. After all, the routers are made in Bosch factory by Bosch blueprints and under Bosch supervisory.
In fact, all the routers (B&D,Bosch) in the store on that particularly shelf had famous ''Made in PRC'' logo on the box. I can go further and say that most of the B&D and Bosch power tools sold around here are ''Made in China''. I am not sure about Makita, Hitachi and Metabo but I can check the next time I'll be shopping.
By the way; I live about an hour drive from Ljubljana and about 2,5 hours drive east of Venice - for all the others who don't know where Slovenia is. I hope all of you will take the last remark as a joke.
Regards

So where ?? That covers a broad swaithe from Postojna round to Bled. My nearest Chinese restaurant is in Koper, as is Obi. I'm in Istria, 20mins from the Slovenian border.

Slovenia, Slovakia and Slavonia all seem to get mixed up !

Cheers

Hi Peter!
Lets just say that I'm right on the border between Primorska and Notranjska. It's not a secret but I'm not comfortable giving too much of my personal data on the net.
Regarding my router problem there is nothing much more to say.

How about router bits made of carbide hardness? What do you use to clean them? I've read on the net someone is using owen cleaner. I think this stuff is agressive and not the best thing for carbide hardness. Is there any other domestic cleaner which gives good results?

I read somewhere recently that oven cleaner damages the bonding between the carbide particles. I use varsol/paint thinner/mineral spirits (all are about the same product). It's a lot more work to get gum off but you won't do damage with them.
