Attaching Slides

I spent a little time last night experimenting with attaching the cupholder slides. The slides themselves were pre-tapped with 3mm holes, but I needed to add a couple more to align with my pieces. I also drilled out the pre-tapped holes and tapped the wood instead, so that the bolt head pulls down on the slide and locks it against the wood. (If you screw though one tapped piece into another tapped piece, they’re never really drawn together because the threads will keep them at a fixed distance from each other no matter what.)

What’s with the playing cards? I cut the groove just slightly wider than the slide so that it doesn’t bind up as it slides back and forth. The playing cards make sure the slide stays centered in the groove as I cut my holes and bolt everything in place!
