get the big plastic bins with lids from Target/WalMart/etc. Fill them with the bits that take up space, but have limited or seasonal use. Try to categorize and label the bins.
Find 'space' like attic, rafters in garage, under table, under stairs, etc. and put the bins there.
pretty basic, but it works for us.
Another thing is to build/buy shelving, and make a giant wall for the bins. Did that at my last apartment in parts of the garage. Pretty cheap, just 2x4's and some plywood.
If you need tools for wood working, let me know. I have some basic stuff.
DUDE, Seriously, GET OUT OF MY HEAD!
hahahha I am a Rubbermaid Bin Whore! I am an organization freak, I have a place for everything, unfortunately, everything is not in its place at the moment.
What I did in my garage:
rip sheets of 3/4 and 1/2 plywood in half to get 2 ft x 8 ft boards. Laminate on 3/4 and one 1/2 together. Router two channels 3/4in. wide per side of laminated boards to accommodate the metal adjustable shelf brackes. Assemble with a top and bottom and as many center verticles as you need for the bins then cut a bunch of shelves.
I'll try to get a picture up soon. The Rubbermaid storage bins come in various sizes but the most common are 16w x 24d x 9, 12, & 16H. What this shelving system does for you is to utilize the maximum amount of storage space by allowing you to alter the size of rubbermaid bins as needed. it also allows for you to instantly grab just that bin without unstacking a bunch of bins to get to the one you want.
for screws, bolts, nails, etc..., electronic components, anchors, wire nuts, connectors, random misc. stuff,
I took a 2' x 2' piece of 3/4 in plywood, screwed 4 large castors to the bottom then attached 12 60 drawer organizers 3 high, 4 sides to the caster base with some 2x2's to create a 4 sided 720 drawer organizer that wheels around the shop. This unit is the same depth as the Rubbermaid storage bins so when I store it against the wall, it creates a nice flush storage system for the shop. I also got a used steel cabinet from a used office furnature place to house all of my chemicals. Theese three items take up one side wall of my garage.
My thought on the plastic bins. The only bins that I have found stand up to the test of time is the Rubbermaid Bins. the other cheaper solutions, (clear plastic, hard plastic, etc...) have at somepoint failed by cracking or oxidizing to to extreme attic heat or UV. I have been doing the plastic storage bins for about 15 years now and still have all the Rubbermaid ones I started with. I have thrown away all the non Rubbermaid bins due to failure of some sort.
