Burroughs Class 1 Adding Machine Eps 3 Cleaning the keyboard felt

This video is part 3, working on my 1917 Burroughs Class 1 Adding & Listing Machine. In this episode I work on cleaning the keyboard of the Adding machine. The machine has this very nice green felt covering the top service, below the key buttons. To clean between the buttons and key stems necessitated the design & 3D printing of small cleaning wands.

These cleaning wands are designed to get into small areas. The idea is a cleaning fluid such as soapy water is drawn in from a hose from a container, across the surface to be cleaned and out via a shop vacuum cleaner.

If you want to use the cleaning wands for your projects, I've posted them at thingiverse .

Some of the designs labeled as steam cleaner (not used in this video) feature a larger input port and had been intended to use a supply of steam for cleaning. If steam is used, be sure to use a higher temperature plastic such as ABS. For the liquid and simple air vacuum wands PLA is fine.

There's a series of videos on my working on the Burroughs Class 1 Adding machine at.
