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.
