Here are some narrow aluminum shelves I made to store the QC tool holders for the lathe. Bent 3/16" aluminum to about 95 degree angle. Keeps the holders handy behind the tailstock end of the lathe, so I don't have to reach over any spinning machinery.
2nd photo shows the parts I made for apron stop and long travel dial indicator. Made the holder from a block of steel I had (which is starting to rust); the dial indicator holder from some stainless rod, and its clamp from aluminum bar. The apron stop has a pencil compass welded to one end. I also use that for laying out large diameter cutouts to install bow thrusters in fiberglass hulls.
