    SAE Straight Spline Shaft Dimensions

    Thanks for the info. It's hard to believe that they would create a spec this ambiguous, but they did. The good thing is I have a pair of NOS parts to measure, however it doesn't give me much of a sample size. With the information for the 10 spline, your 16 spline, and some other data I've...

    8735 and 8740 Fatigue Data

    Can anyone direct me to the Fatigue Life Data for these two materials: 8735(AMS 6320) and 8740 (AMS 6322). I have reviewed the material spec sheets (AMS 6320 and 6322), MIL-S-6049, MIL-HDBK-5, MMPDS-01, ANC-5, and various texts and on-line sources with no success. The application is a simple...

    24ST Extrusions

    Thanks for your information! I was able to dig up a later version of the same print that calls the material out as a 2024-T4 extrusion, which helps. I am looking at substituting T3511 for T4 with a DER approval. I'm just trying to put together the data to back up this decision. Anyone know...

    24ST Extrusions

    I have an old 1940's vintage print for an extrusion that calls out the material as 24ST and Federal Spec QQ-A-354. I was able to come across this x-ref for QQ-A-354: "Aluminum Alloy -24ST Federal Spec. QQ-A-354, Navy Spec. 46A9," and "Specifications.- Federal QQ-A-354 Aluminum-alloy (AL-24)...
