What nationally of aircraft? What type of rivet?What would be the size range of rivets used in WW2?
Guessing 5 - 15 mm range?
Modelers question, just got a set if injection needles, smallest size is 0.15 mm.
So I'm guessing they can only be used for the larger sizes.
Awesome info!
Awesome!de Havilland Drawing Office Standards:
Head dimensions are going to be found in the particular rivet specifications. In FlyboyJ's example, the MS20426 rivet has 1 set of head dimensions per shank size, with 9 possible material selections and 6 possible post production chemical coatings for each shank size and material.
Here's the MS20426 spec... MS20426 L RIVET SOLID COUNTERSUNK 100 DEG PRECISION HEAD
In this case, the spec is 5 pages of charts, drawings and notes on everything a designer or mechanic needs to select what rivet is needed at the time.
Now multiply this by a couple of hundred standard parts, and it's why one keeps specs on hand or know where to find them quickly. Even the lowly washer has multiple material callouts, multiple finishes and multiple thicknesses......Playing with this stuff, you get real familiar with the codes that you use all the time.
Very nice.On the wing root of the TBMs there are 1/4 inch diameter rivets. They are very difficult to rivet. If you visit the WWII Museum in New Orleans you will see my work. That plane was a fire bomber and we brought it back to display quality.
And the MS specs do not cover many of the WW2 rivets like the Curtiss 87 degree rivets. Lockheed also used some weirdo sizes.
And many of the AC specs became AN specs with little or no change as well tho your L-5 will postdate most of those. Some of the fastener specs were only ever NAS - just to cause confusion.For those that don't get to play with specs much, most of the old AN specs were updated to MS specs in the 50's and 60's, or to other specs in the 70's-90's, if they were retained as working specs. Lots of them were invalidated for new manufacture in those time periods as well. In the case of the Curtis and Lockheed stuff, as well as Boeing, the specs are out there but requires some digging to find. Some of them were company specs that originally had no government spec, but within various repair manuals, approved substitutions are listed. There are some hardware interchange manuals out there too, I've used then to try and update some of the missing hardware for my L-5 project.
Thanks guys!
Not that much of rivet counter, but wanted to know what would be visible in scale.
For future builds I'l only do rivets towards the larger end of the spectrum.
