    Got an older compound that I would like to launch aluminums on again. Looking for an Easton chart with the data for various shaft sizes/bow weights, etc. I had a good one back in the early 90's but can find it. Anyone have a link to a good chart?

    Thanks in advance!

    I just typed Easton Aluminum Arrow Chart into Google and several charts came up.

    I did the same thing prior to my post but I was looking for a particular one that they used to use in the archery shops back in the day. I couldn’t find it exactly. Since this post I have found one that I think will work.
    Thank you.

    Aluminum arrows were marked based on outside diameter and wall thickness...most common shaft was the 2117 (0.21" diameter, 0.017" thickness)...
    The 2117 shaft was spined for most bows 50-65# and 28-32 inch length I believe...

    I shot everything from 2018s to 2314s, which were really en vogue back in the days of shooting overdraws (never really liked launching an arrow with the broadhead actually behind my hand though)...

    That said, most of those old charts were based on OLD TECHNOLOGY and spine vs draw weight and length...the speed and efficiency of modern compounds would likely stress an aluminum shaft more than the chart would indicate...I would advise to spine on the heavy side...

    I also found penetration to be an issue with the larger diameter shafts...the 2018s were slightly smaller than the base of most broadheads (which I think were developed around the 2117s) and performed better for me...

    That said, I have not shot Aluminum in nearly 20 years...

    Teach Deer,
    Not trying to dispute what you are saying but one thing you said is completely new to me. I always understood that the "21" in 2117, was indicating a diameter of "21/64ths of an inch" diameter, not .21 inches. Is this incorrect? Just curious. Thank you for the input, btw.

    21 is 21/64th of an inch and 17 thousands is the thickness of the metal in the shaft.
