I need to make a cut out for a sink in the new 28mm chipboard laminate. I *think* I'm going to be using a Bosch 101B jigsaw blade. That's marketed as a 'clean cut' blade.
I'm wondering whether I should work from the good side of the laminate, or should I turn the worktop over and run the jigsaw from the underside of the worktop? The 101B blade cuts on the upstroke.
I also need to shorten the worktop a bit, and I'd like to use the circular saw for that. Is that going to make a mess of the laminate? Again, which side of the worktop should I work from? The cut edge will be hidden by a bead of silicon, but I don't want to have to use a huge bead just to cover the chips.
I know that the right way to do this is to cut it over-length and finish off with a router, but I'm trying to keep this job as simple as possible. I have already packed a boot full of tools for this one small job. Am I going to regret not using the router?
Finally, I'm going to be reusing the old sink. Can I just silicone that in, using whatever rubber seal is still there, or do I need a special mastic?
