My cabinetmaker & I are trying to determine how to most cost-effecitvely copy a contemporary rolling ladder I saw in Hong Kong for our 16' high library. The tracks on top & bottom were inlaid into the cabinetry & the ladder glided very smoothly along these tracks - I assume some sort of heavy-duty ball & socket joint would be required to make the 45 degree curve? I imagine a local metal fabrication shop could do the track & the cabinetmaker can make the ladder, but we haven't yet figured out the attachment mechanism necessary. Any & all ideas greatly appreciated! I have a photo of the inspiration for this ladder if any good samaritan can help.
Thanks - Sarah
