Ridgeline raceway in framingham ma. is finally switching over from tape to braid. Have finished removing the tape with the help of my daughter.I have discovered a few issues.So far the biggest issue is that the slot shrank.I used water based paint for the slots and think it caused the fibers to expand.so now im sanding the surface then re-routing the slot before i route the gains.i found this out when the gains bit pin wouldnt fit in the slot.This time im going to prime with a solvent based paint.Im also routing the slot depth a bit more. Im thinking all this this will help drop lap times a little.

MDF is funny stuff alright. I resurrected one of our group's best tracks a few years ago, and it was our oldest. The routs were at least eight years old when I got it, and no time at all after it was set up at my place, the slots hydrated and swelled, the thin area below the slots turned to dust, and it slowly disentegrated no matter what I did. I ended up junking the whole thing. That's when I decided that all my slots were going to have hard shell enamel in the slots from then on.
