The perfect place to store my overabundance of horizontal milling arbors seemed to be under a shelf directly below the milling cutter rack.
I haven't brought my Cincinati Horizontal mill online as of yet, but the time is approaching Just like any other machine a Large Horizontal mill requires a lot of tooling to be efficient. The T50 arbors take up a lot of space by themselves and in my opinion, there is only 2 ways they should be stored. Separately in wooden boxes supported in several places along their length is by far the most preferred. it also requires the most space particularly where there are quite a few of them. this would also mean that you could not leave a set of cutters on them when not in use. I like the idea of being able to have multiple arbors pre-assembled with cutters for whatever job run I will be doing, not having to change out several times throughout a job order. So, I think storing them vertically while hanging is the second-best way to protect them.
I have 26 arbors in 3 maybe 4 different diameters ranging from 1" up.
My solution for quick access was to make a shelf out of 10" mobile home frame with 26 1" diameter threaded stubs welded to the bottom of the shelf in 3 staggered rows allowing enough space between each arbor so as to permit leaving most cutter setup in place should I decide to do so.
Later on I will build an enclosure over and around the cutter rack and the shelf to protect them even better.
First I had to section some pieces to the mobile home frame beam together to make a suitable length shelf
Next before I could weld the stubs on the bottom, I had to remove the Asphalt based paint along where the stubs were to be placed. The best way I have found to remove the stuff is to burn it off with a torch
Stubs welded in place
It's not only the arbors but there are a multitude of spacers on them as well some being only a few thousand's wide ranging up to about 4 inches wide or thick depending on how you want to call them. Leaving them on the arbors may be a minor inconvenience when needing to select the correct width spacer but it keeps them from becoming misplaced and they are out of the way
