Outserts for skinny shafts

[Munsterman]

My son is 14 and has taken quite a shine to the bow and bowhunting. Only problem is he has a very short DL and therefore it’s tough for him to generate a whole lot of “umph” (I think that’s the technical term). My thought was to go to a “skinny” shaft like the VAP’s or Carbon Flash(es), with plenty of FOC and a sharp COC head like the Grizzly.

Problem is Carbon Flashes have NO sort of broadhead attachment system and the VAP’s , in my opinion, is ,well, let’s say less than desirable.

So I came up with my own solution….

The aluminum ones weigh in at 48 grs. the brass at 165 grs. I made a test arrow a while back and figure that with his 24″ arrows, he’d need 238 grs. up front to give him a 32% FOC and a 410 gr. arrow out of his 40# bow. These ought to work out just about right.

I thought you folks might appreciate something like this, so I thought I’d post it up.

I thought I posted a reply before, but I guess not. Excellent work. Did youndo those on manual lathe or CNC?:x

Now that would be sweet as peach pie to have 32% UEFOC coming out of a 40# bow. Should connect with a heck of a thump.

they were done on a CNC.

Troy, I thought the same thing. It also eliminates the typically weak hinge point that the factory inserts for these shafts have.

Do you have a CNC or did you hire it out? Do shops do small jobs like that? I have other ideas.

I’m a machinist and the shop I work at allows us to do projects like this if the machines aren’t tied up. Really, for something like this, it would cost someone a fortune to come in with a small order for parts like this. The programming and set-up time alone would kill you before a part was made. I did the programming and set up on my own time (it was for my kid – priceless).

Yea I hear ya. I have a small lathe, but I am NOT a machinist. Have made a few archery items of my own, but it’s time consuming. Not a huge deal on the time, but repeatability is the tricky part for me.

Tell me you have this patented. Brother I’m sure there is a mess of archers that would buy this. Let us know the results on penetration and flight. This IS the solution for my little girl. I hope to see pics of your son’s first harvest with these bad boys.

Actually, no.

We’ve got some mounted but just haven’t tested them yet. I have skinny shafts from 750 up to 500 spine and everything in between. We’ll be testing this weekend for sure and maybe sooner….will keep you posted.

FOC is important, but if he plans to hunt deer with these arrows, overall weight is more important. Just saying not to sacrifice overall weight in a quest for FOC. Of course, if you can get good overall weight and most of it’s up front, even better. I killed my first whitetail as a teen with a 42# recurve, cedar shafts and 130-grain two-blade (Bears with bleeder blades removed) and got good penetration. I have no idea what arrow weight or FOC were. 😆

David,

We’ve kinda set the top limit at 425gr. I know that’s not very much, but this is 40 #’s with a short draw. We’ve tried that and heavier. When he shoots heavier, the trajectory is prohibitively rainbow-like. It just so happens it’s relatively easy to get that arrow weight and high FOC when the shafts are short like his.
