Kozo K-27 Hand Pump
Today was spent machining the flat
brass parts for the hand pump that will mount in the tender. The large
piece is the base plate and the smaller piece above will be screwed to
it and then soldered to form a T shape. The small piece to the right
will be a pivot point on the top of the pump body for the handle and
lever arm. January 15, 2023.
The round stock for the pump body have
been cut to size but I'm waiting on a couple of reamers before all of
the chambers are machined. The small piece at the top will hold the
check ball along with a spring in the top portion of the vertical
column. January 16, 2023.
The horizontal cylinder of the hand
pump has been machined and is ready to have all of the attachments
silver soldered. The visible slot will accept the vertical portion of
the mount at the bottom and there is another slot cut for the pivot
point tab on the top. The vertical cylinder of the pump will go into
the 3/4" bore at the left and the O-ring will slide into the bore to
seal the pump plunger. January 22, 2023.
