Pillars completed / ピラー部品、これよりアルマイト

How many times have I introduced the series of processes of the Center Mount?  I am sorry that very few people seem to follow them, and I have to explain it again and again.

The base of the Center Mount has two-way connetcions to the tripods. One is the direct connection at the 3/8-inch thread on the bottom for the Camera Tripod, and the other is the 60mm taper boss that can be inserted into the extension pillar ( above photo) for the Astronomical Telscope Tripod.
