Technote: Manufacturers Standard Parts:
Every aircraft manufacturer has libraries of standard parts in addition to the MIL specs that are used for their various aircraft designs. These vary considerably covering a wide number of standard parts like bolts, nuts, washers, hinges, screws, grommets, extrusions etc, etc.
When I was working on the P-51 Mustang Tailwheel mechanism I was forever jumping back and forth looking for the various standard parts which was a nightmare due to the large number of files in the archive. This was further complicated as the file names were the scan numbers and not the drawing names. So I figured it was time to get this stuff organised.
I have worked through the archives for the Grumman F4F Wildcat and F6F Hellcat and extracted the Standard Part drawings and renamed them with the correct drawing designations. I have also done a similar exercise for the NAA P-51 Mustang.
The actual drawing filenames have been adjusted slightly to make sorting easier (by group) and make the names more legible. Where for example we have 1E48; this is denoted as 1E-48…the 1E is the alpha-numeric group designation with the numerical sequence suffix. This just makes it easier to read when you have hundreds of files in the same folder.
The excel spreadsheet is a register with the different manufacturers’ part drawings listed on separate sheets in one workbook. This is tabbed along the bottom of the spreadsheet. It is envisaged that each set of drawings as listed will include a download link to an online resource to access the files. This download link for the collection of standard part drawings is located on the top right of the spreadsheets.
The NAA Part Drawings also include the previous specification identifier as some of the earlier blueprints still refer to this number.
This is an evolving project and will be continually updated as more information becomes available with the inclusion of other manufacturers data. Currently, over 400 part drawings are registered. For further information please drop me a line at hughtechnotes@gmail.com.
Update: This file Revision A containing the Standard Part drawing links for Grumman and NAA is now available for download here. https://drive.google.com/drive/folders/1KQbn8FNCwKO8xODLlPB3jTAExa3qygZJ?usp=sharing
