BB, For me it seems that I never have a particular arbor I need. Unlike you I don't yet have a bucket of pipe off cuts, all I got is the press and the two press plates that came with. Everything else is shop made as almost everything around here is automotive related and not easily converted to a small engine shop needs or at least not for my needs.
Now of course I do use a lot my deep well impact sockets for the smaller stuff but there still bearings that are more picky. I usually use an old bearing that is lightly ground so it doesn't stick while pressing in a new bearing if I having to press the outer bearing part in place. Now I have one that I had made for changing idler pulley standoff bushings as have fewer different idlers just they have different standoffs.
But I agree it does takes time to find the right one even when you got them stored one particular place. I got one tool cabinet dedicated just for this which makes it a little easier.
I am thinking about a metal lathe as I am getting to be a pest for the local machinist on some my projects.
Besides I kinda want to keep some my designs secret from the local competing shops.
