Hi all. I followed a simple tutorial on Youtube and built myself a slider. Not bad results overall, as long as you work within its limits.

Coast - Cinematography (Devendra Banhart: Autumn's Child) - YouTube

Is that a drawer slide? What kind?
Impressive motion. Good Job!

Yep, regular drawer slider.

This one Ball Bearing Full Extension Drawer Slide - Zinc Plated - 50cm from Homebase.co.uk (http://www.homebase.co.uk/webapp/wcs/stores/servlet/ProductDisplay?langId=110&storeId=10151&partNumber=422621)

You have to work around the mechanism a bit as there are two parts to the slider and it can cause a slight jolt.
