Worktop jigs

Yes, definitely.

Try the Trend website, I think they used to have a video of how to use thir jigs.

I bought a Trend jig and then sold it on Ebay. Overall cost was less than hiring some no-name version, given that I couldn't get the whole job done during a minimum hire period.

Yup can't see why not.

In which case you should be fine.

I bought a cheapo one from Screwfix and it worked brilliantly. It's probably rather obvious when you think about it, but it seemed very clever the way you cut through in several steps while leaning against "the wrong edge"of the guide, then finish off with the final cut that matters through the whole worktop thickness while leaning against the other edge of the guide.
