At one point I actually thought of looking for a small paint can mixer/ shaker. Then Ward told me what he does. Cost $0--effort 0. Just store the peanut butter upside down. Shit. Works well. And that is what makes a great idea--simple--cheep (sic)--little effort and works well.
Camera Bag Stem Holder--(Christine) --Christine found a cheep (sic) camera bag that has a Velcro tie that goes around the stem. Ward scared me into adding a bungee safety reinforcement. This clears out room in the jersey pocket as now the "bag o drugs" can ride on the bike. (Didn't like the "Bento Top Tube" box as kept hitting it when standing on a climb)
Mini Hammergel Holder --Continuing along the small bottle idea--I hate taking a Hammer grenade for a ride. Not so much for being a weight weenie but it basically takes over one jersey pocket (especially if it leaks)--and on a ride I just need 1-2 shots, not the 5-6 a grenade holds. GoTubes are a perfect size--but but but don't have good squeezable lids. The OLD Hammer grenades with a real screw top lid (not the new ones with a proprietary lid that) work well, so I dug up some old Hammer caps and put them on the GoTubes.
Bottle drying city (Ward) -- Loads of bottles--some drying in the sink--some drying on paper towel --one falls down and there go the rest looking like bowling pins. Ward used PVC to build a bottle drying rack village--pictured below is the town I created. (Ward puts in a few extra long posts to dry out a camelback insert) Write to Ward Industries; POB 000666, Concord, Ca and he'll send you blueprints to make one that looks like the NYC skyline.
Winter Mini Greehouses--Planted a row of baby cactus before winter set in--and cold/ rainy weather the death knell of baby cactus. I knew I wasn't going to run out and cover them with burlap every time a freeze was predicted--and we've had a dozen nights where temperature has gone into the 20's. So got cheep cake servers--drilled 8 holes in each for air circulation, added a washer weight on top and tent pegged them down at the bottom. Winter almost over and cactus doing fine.
