Not just because it's for a plane -- if I knew the guy already I might
make a part or two. It's the fact that a couple of grooves in a pulley
morphed into a design/engineering task -- that means that the guy is
clueless, which means that you can't trust him to build the rest of the
plane right.

You don't have to trust him to build the plane; it's an experimental.
The _instant_ he puts a non-STC'd part on any aircraft, commercial or
otherwise, it becomes an experimental aircraft.

I, too, would turn down the task because the guy didn't have
specifications -- only hopes. But the liability risk is actually pretty
small. NTSC doesn't have jurisdiction over experimental craft, and
experimental pilots crack up all the time.

But it's not the NTSC that brings liability suits. It's the relatives
of the deceased, and the ambulance-chasers who find them.
