You don’t have or can’t find oft-used tools and supplies when you need them.
One way to keep tools handy is to keep different groups of them in inexpensive portable caddies like you can buy in the housewares department of a hardware or variety store. Molded plastic caddies with built-in handles are made for organizing and storing cleaning supplies and other household goods. But they’re equally as useful for workshop items. So, for example, when you need your marking and layout tools (calipers, 6″ rule, dividers, tape measure, etc.) you simply grab your “layout tool” caddy and take it right to the benchtop or worktable.
You’ll have all the tools you need and are less likely to lose tools, as each goes back into the caddy when you’re done. When doing household repairs or working away from the woodshop, it’s particularly great to have all the stuff you need at hand, so you don’t have to keep running back to the shop for things you’ve forgotten. Tool caddies are also terrific for organizing screws and fasteners, glues and applicators and other shop supplies. Larger caddies or trays can be just the ticket for keeping small parts together, especially when moving them around the shop for different machining operations.
