Back in Business

Usually, it takes just a couple of tools to tension Paragon Sliding Dropouts; a 5mm allen wrench and a 5mm box wrench. However, the hex bolts are made of a very soft alloy and if they are not properly lubed they can require significant torque to remove. Sometimes the amount of torque required exceeds the the ability of the bolt to maintain structural integrity; i.e. the bolt head rounds out.
At this point, a few new tools are required.

First, get a drill. Make sure it is old, the chuck is weak, and the bits are dull. Then proceed to drill a pilot hole for an ez-out. Great so far! Now, reverse the drill and attempt to use the ez-out. When the drill starts smoking and you smell ozone; stop. Let the drill cool off and then try it again. Repeat until the ez-out breaks off inside the bolt head. Ok, you are done for today and need a few more tools.

Got to the hardware store. By a dremel tool and a very wide flat screw driver. Cut a slot in the face of the bolt. Watch the pretty sparks as the cutting wheel contacts the hardened steel of the ez-out. Use the screwdriver and an adjustable wrench to work the bolt loose. Success!

Sorry for the blurry photo. Anyway, if this all works out you get to convert your mtb from psychocross to night-rider configuration and end up with something like this:

Ah, good times!
