I've got loads of Scalextric Classic track. I remember it catching me out, a few years ago, when I used adaptor straight to mix Sport and Classic. My Escort Mk1, just stopped dead! Luckily, no damage.

Has anyone tried routing the Classic track slot, 1mm deeper? Something I have been considering doing. Yes, I expect it will weaken the track, but if it is going on a permanent layout base board, this should not be an issue.

I must admit, I always chamfer the front of my guide blade, just in case there is a slot depth issue, on rally stages I have no personal experience of. Certainly, one of my cars was touching the bottom of the Classic slot, on this stage, but the chamfered blade prevented any real issues. 

I must admit that the "6mm max flag depth" rule, made me expect that all stages had slot depths for 6mm or greater.
