Straight cut using a router

[grifter]

I have a 40mm laminated piece of worktop which is bullnosed on both sides as it will be breakfast bar. I want to cut it to length to leave a clean cut edge showing on the end to finish with worktop edging. What I was wondering and before I attempt the cut, will it work if I clamp my worktop jig and set my cutting line as normal like for mason mitres and run my router in from both sides, into the post formed edge, obviously from left to right both times, and create a nice straight cut? Will it marry up ok, and most importantly, will it be safe to do this as I will be stoppin the cut along the length each pass?I've been thinking about this, and can't see why it wouldn't work, but am I missing something.
If the router is not an option, will a circular saw cut the full length still as the blade will still be cutting upwards into the postformed edge with the worktop upside down from one bullnose to the other.
I hope you can understand what I'm trying to explain.

As long as you clamp your jig tightly and in alignment then it shouldn't be a problem getting a flush cut. Remember though that you need to turn over the worktop for one of the cuts.

As Daz says, better to go halfway across from each edge as one side will have to be done with the worktop upside down so your cutting into the laminate. If you cut straight across form the top side, when you get to the opposite side, the router will tend to break the laminate off the radiused edge.. Alternatively, if you know someone with a Festool TS55 plunge saw and rail,, ask them to cut the worktop for you. This will go right through without any breakout.

Thanks for the replies guys. Maybe I'm still missing something, but if I cut from left to right as normal and remove most of the material short of the opposite bullnose(I realize I would break out the laminate by exiting out this way) would I then not be able to go round the other side of the worktop and enter the opposite postformed edge from left to right again and remove the rest of the material. I'll be looking at the worktop from the other way round, but still starting a normal cut into the bullnose, and my cutting line is the same as I'm following the jig with my 30mm guide bush. Am I making sense? If I'm being thick please tell me and I certainly don't know anyone with a plunge saw. Thanks

what you need to remember is there's some play in every contact surface within the jig bushes and guide
the router cutter will in direction off cut pull tight to that side so all slack in one direction will be doubled in the opposite direction as the cutter pulls
in other words left to right [anti clockwise ]the cutter pulls away from you right to left [clockwise]the cutter pulls towards you
