Hi

It's not unusual to leave a small gap, it's what the analogue boys do, this allows the builder to paint the slots different colours for id ing the lane..

The mdf lifting is down to your choice of mdf, it looks like it is fluffing up once you've machined it so indicates contract grade mdf, no issue with that but it does require a little more work to get a nice finish, one trick is to paint the slot with diluted pva, this hardens the surrounding mdf but it will all the fluffy buts stand up so it will need sanding before fitting the braid..

Regards fixing, yes good quality double sided tape will work great, especially if the steps mentioned above are taken as this also seals the mdf and stops it bleeding dust which obviously effects the adhesive on the tape...

And welcome to the forum

and to the world of routed slot car racing
