I'll suggest, being as we all have some manuals, an easy way [to me anyhow] method of making personal list. I've built up a substantial shop on my own, and keeping track of what's in and what's needed is a puzzle.
Here is my method; works on anything you'd like to inventory. Books, reloading supplies, hardware, tooling [hint; inserts!].........
All kinds of software is available at a cost but you probably have the simplest already....
a] Decide on a definite naming structure as in Reamer, 5/16, HSS, carbide tip, straight flute, straight shank, quantity. Collets? Separate them under individual heading; 5C round-square-hex, WW, 2J
For print manuals Grinder, Drill, Black and Webster, Model....if you add serials use a separate column or pop-up. They aren't beneficial sort headings. If you have several identical screw machines [etc] though, that makes replacement of not universal parts easier.
Eventually this will be sorted how you chose A-Z, 1-2-3, are the main avenues.
b] Open excel in speech to text. Lets say manuals, read off brand name, or very brief function Grinder Surface; Grinder Drill, Grinder Tap, Grinder Cylindrical. The alphabetical order will not matter, sorting will take care of it, long as you maintain strict protocol.
Maintaining that you can now just go from corner to corner Grinder...Milling Machine, Lathe, Grinder, Punch Press, Grinder, simplifying very complete coverage.
c] Once in awhile, sort the list. The categories will fall into perfect order, whether it takes a few hours or months. Buy something? Add it. Sell something? Delete.
It's now portable sent to phone. Go to garage sales, auctions, or dealers? Hmmm, here's a nice tailstock for my indexer, what centerline is it again? Wow 7018 electrodes, ohh I already have 100 pounds....
We all have more than one toolbox. Machining, plumbing, welding, painting, this works just as well.
