Homebrew Blood Cootie.
This key is mounted on a 3.5" x 4.5" x 1" thick blood wood base with wooden finger piece. This Cootie is made from 1" x 1/8" thick aluminum angle stock and hardware obtained from Lowes using simple hand tools and small band saw. I put it together in one afternoon! It works very well and has very smooth action. I installed a switch so it can be switched between Cootie and Single Lever paddle mode. Used with my K1EL K42 keyer this key is capable of being a Cootie, BUG or Fully Automatic single lever key. [N3HEE].
Homebrew Heavy Duty Cootie.
This key is my newest creation. Mounted on 3/4 inch thick brass base with machined solid aluminum parts and finger piece. Thumb screw adjustments for quickly and easily moving the blade in or out to adjust tension and feel. Weighs about 2.5 pounds. It only operates as a cootie. Very stable on the table ! [N3HEE].
