To finish with the wood lathe, here is my woodturning tools rack :
It is a T shape tray, bolted at the end of the lathe bed.
Sometimes, when I really need to use the full length of my bed, I just have one bolt to remove to get the full length back.
Here, at that place, I feel the gouges are exactly where they need to be. The hardest thing is to get the discipline to always put the tool back to its own place when you no more use it, instead of putting it on the front shelf ...
