Using rods to store parts, Bearings, headsets, pedals and etc.
You can use rods to store Bearings. Take a 2x6 and add wood rods of appropriate size for each size of bearing you use. Clean the bearings before putting them on the rods and they will be ready to use when you need them.
Use wood rods or conduit to create another board for storage of Bottom bracket cups and headset parts.
this was constructed using two 2x4's with a plywood top. Caster wheels were added to the bottom. Take conduit and flatten it in the vice leaving about 2 inches still round on the bottom. Drill a hole and hammer the conduit rods into the holes. Now add pedals. These are paired. (the single pedals are stored on a rope with hooks made of spokes.)
Here is a decommissioned tool rack. Nail brads at the top and hang the chains.
