Week #14 & #15A (4/27-5/4): Blue Prints, Technical Diagrams, Mechanics.

[rjagodowski]

We will spend this week discussing Blue Prints and other Technical Diagrams such as electronic schematics & ladder diagrams, then on to discuss some mechanical concepts.

Here's a handout on Blueprint Reading:

basicblueprintreading-1 per page.pdf

Details on Electrical Drawings start on page 55. Fluid Power starts on page 100. Piping and PI&D drawings start on page 150. Civil and Architectural starts on page 175. Machine drawings start on page 202.

Or if you wish to print it (still a lot of paper):

If you wish to print this, this one puts 4 slides on one page.

For the Blueprint Reading document you should read the first section as an Overview of the various types of drawings. Then you should spend time studying the Electrical Drawings (Page 55), the Fluid Power Drawings (Page 100) and the Machine Drawings (Page 202). You are encouraged to look at the Piping and PI&D Drawings (Page 150) as these type of drawings are frequently used in Process Control Systems. Lastly, the Civil and Architectural Drawings (Page 175) should be reviewed. For Civil Drawings, of specific note are the Contour Maps & Site/Layout Drawings. I know of at least two students who graduated from this department within the past 12 years who were employed by a utility and their job was to verify, edit and modernize various drawings showing utility right of ways and access points.

Does Anti-Seize Compound Actually Work? (14:31) by Project Farm on YouTube. I've watched many of his comparison videos. He is very unbiased and thinks of real clever ways of testing tools, lubricants, adhesives, cutters, etc. I recommend that you check out his Project Farm YouTube Channel to see if he has tested something you might be interested in purchasing.
