I was just reading Dr. Ashby's report and was wondering what is an internally footed arrow? I have lost a deer before when shooting a compound and am convinced that I could have recovered the deer if I would have had a better arrow setup. Now that I am into traditional archery I think it is even more important to have good arrow flight, whereas before I just thought you had to hit what you are aiming at! The report is very eye opening to say the least.

Much of Doc Ed's work has used carbon-composite arrows simply because they are hollow and thus provide lots of room to experiment, including inserting various weights inside. The only internally footed wood shafts I'm aware of are individual experiments, my own included, involving drilling out two or three inches from the head and inserting lead wire or a nail. I'll bet mmgrode's link will tell you more. I don't recommend drilling wood shafts. Footed shafts are great but darned expensive. Before next fall, there will be some if not several 200grn neighborhood first-rate glue-ons available that also incorporate Ashby's many other recommendations. I think now is the time for patience rather than investment in the Ashby-style broadhead arena. My 2senze, d
What Mr Petersen said.
I built a jig for 11/32 that allows one to drill an 1/8 hole three inches down the center of the sahft. I insert a piece of bamboo. I do this to strengthen the tips as we break many arrows on rocks-yep NV has rocks. the bamboo is flexible enought o absorb some of the shock and prevents boot-top breaks pretty well. I have also put coper or anils in to heavy up the point, and have drilled out the nock end to lighten that up a bit.
The other thing I have done is to band saw a kerf ddown the center of a shaft for about 6 inches and glue in a heavy hardwood. I then sand it down and taper the point. This gets me a tough shaft and adds weight to the end. agin it weights forward, but i use it to extend the life of my shafts from these omnipresent rocks.
Gordy Mickens used to fit his carbon shafts with a piece of hardwood and glue a normal glue on point tot he wood. Either of these methods will put you where Ashby is heading-without a lot of science between thes4e actions.

These are internally footed carbons.
I think I'm starting to understand what a footed arrow is. I was under the impression it was for making arrows with extreme FOC. I guess they're also for "fortifying" the front end of the shaft. Am I getting the idea right?
Yes you can make easily an EFOC arrow setup without footing.
I'm under the impression that footing is there to fulfill what Ashby considers the MOST important aspect of arrow penetration on game: structural integrity.
