I bought myself a countersink drill bit and some tiny flathead screws so I can research screwing down my track to the board. Not just to keep it straight but to keep the waffling to a minimum, which is something that crops up quite a bit on the seamless track.
I used a wide popsicle stick as a washer which worked much better than I expected. And so far I haven't seen any negatives to it. The walls aren't pulling in and there's not serious bump created in the track. All the cars I've thrown at it have plenty of clearance both vertically and horizontally between the wheels.
All that being said (and being positive), has anyone else gone through and screwed their track down and maybe have some real world words of wisdom?
If there are any gotchas to watch out far, I'd like to try and duplicate them on my test track segments before I go drilling into my seamless track.
So far it's gone better than I expected so I'm hopeful. Any thoughts or insight is appreciated.
