Making an IF

When making an IF, does the taper need to be special (measured, convex, etc.) or will a straight taper behind the parallel section to a smaller diameter be enough?

I think an ‘eyeballed’ convex would be the ticket.

Thank you! Now to get some dowels and start sanding.

Kegan — it seems that few of us here have experience with this issue. Please share your results and educate us. 🙂 dave

I was reading through some of what Dr. Ashby wrote about IF’s, and it seems that the trailing endge isn’t that big an issue, but matching and fitting being more consuming. No problem. If I can get photobucket working I’ll do a build along so all can see, and possibly help me along.

Of course, I’ll have to do a test with the first one to see if it actually holds up (that is, to see if I did it right)… poor sacrificial lamb:cry:!

Finally got around to making up some IF arrows. I used the Gold Tip 400’s, 100gr brass inserts, carbon collar from 3Rivers, oak dowel internal footing (3.5″ parallel, 5.5″ tapered section), and my normal 250 gr points. I only had six, but I made them up as best I could. They finished off at 700 gr and felw straight out of my 73# selfbow. With broadheads they flew straight and hit hard. Maybe not buffulo gear, but they’d be good enough if I ever had the chance at something really big here in the states.

I was suprised at how easy they were to make. I read through Dr. Ashby’s report where he said that despite the differences in taper, all of the IF arrows survived. These held up to the tree test, and since I don’t have a Grizzly on there for really wicked critters, I figure that as they are now they would be more than enough for even the most off the wall North American game I may have the opportunity to use. I shaved down a 1/4″ oak dowel, used a hand plane to taper the back, and then just sanded it up. Not an issue at all.

Thanks for all the help everyone!

Kegan — Congrats on your experimental success! And thanks for getting this thread — and this entire forum — going again. Darn shame that without leaders in this arena — Ed Ashby, Sharpster, Kingwouldbe — it gets so little action. I mean, there’s a lifetime of discussion potential here! Given the high draw weight of your bow and the arrows you’ve now set up, and assume the right head, I’d say you could line up any two of the biggest thoughest game animals in N.A. and shoot through both! 😆 Of course that’s a “joke” for the argumentative literalists among us. But I’d sure not want to be on the receiving end even if I were a big bull buffalo. Thanks for your tenacity. Keep us posted. dave

Thanks Dave! I like having been able to use arrows that otherwise would have gone to waste. And that they can go through big ol’ critters, that’s just a nice bonus:wink:!

If I ever get them into something furry, I’ll be sure to let you all know how they work. If anyone gets a free set of light carbons, I say jump on it! These IF’s are a piece of cake compared to some of the other stuff I’ve tried, like juggling or listenning to the evening news:lol:.

Did you see this thread and are your IF’s similar?

Kegan thanks for keeping us updated. I am going to see what I need to have ultra EFOC with my 40# bow. I have just bought 100 gr brass inserts and am going to install them this weekend on my GT Expedition hunters. I’ll open up a new thread and I will keep following yours.

Yes, my IF’s are similiar to Dr. Ashby’s. Actually, I built mine around what Dr. Ashby wrote on them:D That thread in particular did alot towards giving me an idea of what the IF looks like.
