Rack for horizontal mill cutters- ideas?

[Pete O]

I need to make a rack to organize & store the bonanza of mill cutters I scored a while back. I'd appreciate any photos or ideas of racks that others use. I'm thinking of a frame of RHS (square tubing) with, say, 6" lengths of 3/4" pipe sticking out near horizontally- but slightly angled upward- to take the 1" spigot bore of the cutters, sorted by thickness. Ideally I want to mount the rack in the 'compactus' shelving unit that I've just installed in the workshop. Don't want to reinvent the wheel and then learn of a better way, as so often I find myself doing!
