A Common Language separates many of us in the USA. Liberty to some means take all you can get when you can get it. While most of the sane, rest of us, believe liberty is sacred, is earned, must be maintained and at its root core is respect for the rule of law.
But a Common Language also means translating schematic diagrams to a form that can be described to a CNC Mill. At times schematics must be redrawn so that they are more readily adapted to CNC Milling.
The W3IRZ schematic was redrawn to reflect the reality of the actual pin positions on the 6BA6 tube sockets and a thought of position of the controls once it is built. Think of a front panel with the Tuning dial in the center, the regeneration control in the lower left-hand corner and the headphone jack in the lower right-hand corner. Confused... hang on.
Ground Pin #2, 6BA6 #1 -- it's missing in this sketch.
A subsequent step in the process is to take the above schematic and create island squares of the connection points of components, which generally follow that layout. This is an interim sketch and then those squares will be identified on 1/4-inch graph paper where coordinates will be identified, and this is what goes into Carbide Create to generate the G Code for milling. These same coordinates are a roadmap for the MePads/Manhattan crowd that use glue.
Redrawn schematic to include island squares
Now that we have the approximate location of the island squares, we can go to our graph paper and with the actual parts move them around the paper to ensure a proper clearance but also to minimize actual component spacing. The 7 Pin shielded tube sockets will be mounted on pillars and elevated slightly above the PC Board base plate.
Next in this exciting discourse series, is the island squares for the 2nd 6BA6.
Further Refinement of the Layout
Our process by using the initial sketched pad layout and then using the actual components enables a smaller footprint with the actual components. We can now go to Carbide Create to get the G Code. You will note I have included some of the reference points if you were to take this to Manhattan Construction... you would be good to go. The coordinates are to scale. If getting the 1st set of knickers off could only be this easy.
Sometimes the most obvious approach is not the best approach. That is a hint to the success of this project.
BTW a blog reader sent me a link and indeed Mike, W3IRZ is a SK, since 2003.
Them that know can make it go, the rest wished they could.
Things in downtown IRAN don't look good. Pray any of you who have children or grandchildren who are of draft age that they may not have to serve. War is not fun and dodging death takes its toll. Was what happened over the weekend really necessary? But it does move the discourse away from the Epstein issues.
