This was a super fun build for me! I have been wanting to do it for a long time, but was a little intimidated with the hardware. I bypassed the expensive kits you see online and built my own from aluminum flat bar, carriage bolts, and sliding door pulleys. I am very pleased with the overall project and wish I would have done it sooner! Shortened down to 6', and I opted to make 3 "openings, with the middle being the same as the outers, doubled, to insure the doors matched up.
Varathane Ebony (top and outter planks of doors)
Minwax jacobean (middle door plank)
Multiple coats of polyurethane
