how do i disassemble an old campagnolo record front hub? i am having one hell of a time trying to figure that out. i have disassembled many front hubs but these are completely different as there is no way to use a cone wrench on these hubs. whats the trick?

this is exactly how my hub looks:

The outside end of the hub shell comes off, revealing the flats for the cone wrenches. There's a special Campy tool for this (naturally), but you can do it with two screwdrivers prying up on opposite sides of the cap. Pry evenly- there's a hairspring between the cap and the shell that can get lost if you're too rough with it.

Here's Park Tool's take on the old standard hub with loose bearings. Be sure to measure the bearings before replacing them. Grade 25 Chromium-Steel is the most commonly used ones:
