rim wrench
copy of the morningstar rim rench. made with a junky 8in adjustable that i picked up on the side of the road during one of my commutes. strong enough for this purpose and you wont destroy the good stuff. tools used were a hacksaw, dremel and bench grinder

stripped crank puller threads
when the puller threads are stripped on a crank i usually use a pickle fork. the one sized for tie rods is the right size. i also have a set of jacobs chuck wedges. size number 2 has a 9/16 slot that fits. the wedges don't really damage the crank. the pickle fork is faster and does some damage
sock it out screw extractor
these things work awesome. they are basically a tapered hex key. removes stripped out hex screws. get some. http://www.sockitout.com/

cable head stuck in sti shifter
digging out the cable head can always be fun when they break inside the shifter. sometimes i use a pick to force the shifter gear to the highest gear position while clicking the shifter. a set of tweezers also help to pull the head and keep it seated while you click the shifter.

impact gun
impact wrench is great tool and knuckle saver. i use them to blast off chainring bolts and rotor bolts mostly. pedals too. i would get one with and adjustable power knob or regulator to limit the power. i have a little ingersoll rand butterfly impact that i use on rotor bolts and chainring bolts. got a bigger pistol grip one for pedals
cable cutters
these knipex cable cutters are hot. love em. sharp tips to nip the pig tail off of brake housing. crimpers work for ferules and end caps

praise to the pedro's bb socket holder
one of the few pedro's tools that i like. when you need to lay down the power this is the tool you need to keep the bb tool from slipping. easy to make at home but you will need to source a few things. i like the pedros version because it works on isis and octalink bbs. a m8x1 fully threaded bolt and nut. m8x1 is not too common but you should be able to get it at a industrial supply place. m8x1.25 is common at most hardware stores so watch out

cup and cone bb adjustment without taking the crank off
quick way to tighten most fixed bb cups without taking off the crank is to use a 36mm headset wrench. it fits most of the time to check the tightness of the fixed cup. i also grind down my pin spanners to sneak it past the left arm. new style ones that use a 20 tooth spline are a bit harder to do without taking the arms off. drive arm must come off but the non drive side i can usually wedge a screwdriver to turn the cup

stuck or corroded threadless fork
many will want to just drive the steerer tube straight down but this is wrong or much harder than attacking it differently. if you try to drive it straight down you are breaking the bond of everything at once. there is lots of surface area. driving it down also wedges the split wedge tighter and grips the tube. very hard to do. knock off 1 piece at a time. spin each spacer to break the bond. sometimes i use some rubber around the pliers but if its stuck good go for the teeth. after one is spun drive it up with a screw driver or putty knife. now sand the corrosion off the tube. repeat until you win
