Worktop is 635mm but Jig doesn't have this slot... What to do?

Don't worry Veedee, I've got a dewalt with 2 tracks, and it's one of my best bits of kit. I've now got to work out some way of getting a perfectly straight line when both tracks are joined. I've just built a window box seat using 8x4 ply and mdf, and the other half's damned pleased with the result.

You're a star!
