I timed my spin to 2mins 20 seconds. Not too bad
The rail systems are over $50, typically.
Get some decent bearings - I used these @ $10 for 30 - https://www.amazon.com/gp/product/B002BBD6X4
For those bearings a 5/16" steel rod (about $2/ft, purchased at Lowe's) fits in nicely. Mount two of those bearings on the rod and sandwich it between two pieces of wood (or steel if you desire) and it'll ride atop a 3/4" wood rail smooth as butter. Put as many of these as you want along the top of your barn door and for about 1/10th of the cost you have the same thing.
I need to finish up and post photos of the system I did, it's just too expensive to buy a few pieces of metal.
Amazon, we got a pack of 30 for ~$12
