Depending on your woes, you may need
1x butter knife
1x roll electrical tape
2x compact discs that suck
Step 1: So it's Broken in freakin' Half
Trust me, stick to this.
The problem with the drum pedal is that the plastic flexes again and again, inducing stress and flex, and ultimately weakening the structure. It's pretty much inevitable that this will break.
To temporarily repair a split pedal, or to prevent the flex that could kill your well used kit at any time, all you need to do is reduce pedal flex.
I used a thin flat butter knife. The purpose is to provide uniform reinforcement to the pedal. The tape will hold it together well enough for a night, and the knife will reinforce the pedal itself, preventing the damage from worsening, or holding the thing together if it's already screwed.
You know what they say: more tape is more better!
Step 2: Then Fix it Right
I got a $20 (after shipping) Drum repair kit off of ebay.
A word to the wise: Spring for the $10 kit with hinge reinforcement.
Step 3: So then (now) your (my) hinge snapped off!
But once you reinforce the pedal, it just shifts the stress. It shifts it straight back to the hinge, where high school physics tells you that the force on teh fulcrum is dramatically increased by force on the tip of the lever.
Sure, the plastic looks strong, but physics says otherwise.
Step 4: Steal Ideas from Others
I looked at the hinge repair kits, which (at the time of publishing) you cannot buy separately from pedal repair, and I saw just how it works. They don't REPAIR the hinge, they REPLACE IT. They use a square of lexan to reinforce the pedal, to connect it to the heel rest, but it is also flexible, and not susceptible to flex-ware out.
Well crap! I have Lexan scraps lying around! They're called CDs! (note, CDs may not actually, chemically be lexan, but neither may be teh crap on ebay. the point is, they are GOOD ENOUGH.)
A real, burned CD has a lot more flexibility than a burned cd, so use an old AOL disc is you have one lying around. I used a demo for America's Army that I got at PAX last year (see, you should go, look how handy it will be).
You will want two CDs, just to be thorough. One should do the trick, but really, when are you ever going to listen to your Spin Doctors CD (the second one, not the album with "2 Princes") again?
Using a pair of scissors, cut them to basically the width of the heel of the drum pedal.
Step 6: Reinforce the heel. REALLY WELL.
Remember, more tape is more better. Get that thing on tight. Electrical tape is flexible, is this to your advantage by pulling it tight around the unit.
And now you're done! This whole thing takes about 15 minutes, so you can be back to your party in no time. It's also easy enough to do while hammered, though you may want a designated driver to handle the scissors.
Though the hinge fix is mickey moused, mine lasted for weeks of heavy use.
Until the magnetic switch itself broke.
I don't have a fix for that, so I'll finally have to send the stupid thing back to EA.
