So I'm not a techno weenie but here goes.
Footed shafts around since at least 1545. Internal footing new as far as I know.
Making my own equipment is part of the hunt for me. So I began making my own shafts from boards. Ash was a favorite. But with each board you get a different gr weight shaft. My first came in around the 650-700. Next batch came in at over 750 finished shaft with 190gr point/braoadhead. More weight than needed. Trying other shaft woods lead me to poplar (others mentioned it on this site) My first board the shafts came in around 350gr light and a chance to try internal front loading. 3/16 brass was internally footed to add a extra 100grs but the shaft became weak behind point and broke not enough wood to protect I guess. Next board closer to 400gr and a chance to try footing and maybe 1/8 brass.
Using the AMO measure method here are some results that I got last night.
All shaft are around the 27.5inch from throat of selfnock to BOP. Except Birch it is plastic nock. All shafts have 190 glue on point.
Plan shafts FOC:
Ash 14.5%
Birch 14%
Douglas Fir 17%
Poplar 15.5%
Footed shafts FOC:
Poplar and 100gr internal brass 22%
Purpleheart 6"taper2.5"foot 18%
Bloodwood 6"taper2.5"foot 19%
Bloodwood 5"taper4"foot 19.5%
Purpleheart 5"taper4"foot and 25gr interanl brass 21%
