Circular saw – warped base plate

[J4m3sg]

Hi everyone, I’m an absolute noob, so apologies if this is a stupid question.

I was cutting some ply with my circular saw yesterday and I noticed the cut is not completely straight in the vertical plane hence it is giving everything I cut a slight bevel.

I used a square to align the blade with the larger part of baseplate, however I was still getting wonky cuts. Long story short I spent a few hrs fettling it, and couldn’t for the l life of me get a straight cut. I then checked the blade for square against the smaller part of the baseplate and found that the if I go the blade sq against one side it wasn’t square on the other side.

Current thinking is that the base plate is bent. I think I can get it off and check for any wobble on a flat surface which will tell me for sure, but before I do is, there anything else it might be, or is there a better way of checking? I Can’t think of any other explanation to be honest….

Throw it away. if the baseplate is sheet metal, it will have stretched locally in the region of the bend and will never go back as originally design. If is diecast aluminium, then it will likely crack if you try and reshape it.

If it is a quality make then base plates should be available as spare parts.

If you can strip it easily then do check it on something flat like a work top or thick MDF, it might just need a tap here and there to correct it.

I bought a cheap router where the base was bent, so I glued a piece of perspex on to it with epoxy effectively flattening the base.

More details, make, size, etc and some pic's would make it easier to help, if someone can.

thanks all, its an Evolution rage 2 jobbie from screwfix. Got the blade out last night and there is a definite fall off on the outer edge of the thin side of the base plate. Might be able to flatten it, or I'm thinking of attaching an MDF base to the existing base plate.

Can't find a rage 2 saw bench, only hand held's, If it's hand held and the base has been damaged try and get a new base for it.
But if it's like this one it will be a different story.

Wouldn't that happen to be a Bosch of the amateur (green) line by the merest chance? On the one I bought half a dozen years ago the blade isn't parallel to the base by about 6 degrees, on the side of the base one would lie against a batten or any other guide. I couldn't manage a decent cut and couldn't understand why until I eventually decided to check.
As the base is riveted to the blade cover, there is no way to readily align it, so it remains sitting in a closet ever since, until I find a good reason to waste some hours on it.

My Makita 5603R had the same problem it took me some time to realise it was a problem with the saw not my technique.
I filed one side or the front pivot on the main casting and added a washer to the other side to get the blade in line with the base.
It's part 24 in this diagram http://www.powertoolspares.com/tool/mak ... 3r/spares/ zoom in to the exploded diagram for a better look.

It works so much better now.

Thanks all - I got the base plate off and sure enough it was wonky. Attached a secondary plywood one with the same apertures etc in it, which has helped already - Might just need to drag it across some sandpaper on a flat surface to even out the tiny camber on it.

I looked into buying a new baseplate but with P&P and Vat I could almost buy a new one. Plus it is riveted on so I'd need to tackle that too.

Didn't like the idea of a chucking away a perfectly good saw anyway so hopefully the plywood base will help - I'll report back...
