I have a 6 level wooden shelf system. I need to make one of the shelves slidable through addition of shelf on top of an existing shelf as shown here:
This should be a smooth action back and forth. It will need to be able to hold up to 40 lbs, but this load will be at the far end (shelving side) and will never extend past the existing shelves once the shelf is slid.
What's the best/ cheapest way to do what I want here?
Thanks, Tom
