TR6 Rocker Pedestal Question

["Kai M. Radicke" <kmr@pil.net>]

Why on earth are the holes in the rocker pedestals, for the bolts, tapered?
So that the top of the rocker pedestal has a properly sized hole to
accommodate the bolt, and that the bottom has an oversized hole much wider
than the bolt itself?  The entire length of the hole is rather cone like
with a very visible taper.

Quick measurements:

Top, hole diameter:         10mm (0.39")
Bottom, hole diameter:    12mm (0.47")

Cheers,

Kai (spending too much time staring at the pieces of his dismantled motor)
