Adding weight to Deep Six shafts?

Good afternoon,

I'm going to put 2 deep six inserts up front on my FMJ Injexions....I was wondering what else everyone has used to get a bit better FOC, while still using the 100 gr points (limited by the # of deep six 125 grain heads available)


Thanks!

I know you don't get it becuase you keep bringing it up..........but for the others that are using FOC as their prime criteria when setting up a hunting arrow;

You are much better off concentrating tuning your bow for BH's and on getting all of the components right on these skinny shafts as the outserts are notorious for being the that weak spot of these skinny shafts. By weak....I mean just that weak/break....and then there is the fact its difficult to get those outserts perfectly straight.

These skinny shafts were around decades ago....and the problems weren't the shaft...but the outserts. If you have to have these skinny shafts you should plan on purchasing the expensive CNC machined steel inserts...and develop a good process for installing them perfectly straight. Everyone dumped them. They are great with integral target points...but it doesn't convert to BH's.

Making sure you aren't underspined [overspined tunes fine and gives you a more durable arrow] Bow tuning, perfect arrow assembly, arrow weight....all much more important than FOC.


There is one guy that started this whole extreme FOC thing and its taken on a life of its own....until one of his 'Scientific experiments' where he claimed better trajectory with EFOC was exposed as junk science. He claimed he could break the laws of physics....oh and he was using rubber bands and wooden dowels to prove the EFOC thing. [its since been expunged...laughed at by the scientific community] Is that where you want to get your advice?

To put it bluntly;
Don't buy into that garbage......FOC is the least of your worries. If it was a big deal every competitive archer would be piling on extra FOC.....and there is ZERO pros that are outside of the Easton recommended range. ZERO.

Its actually funny....the guys talking about 'FOC'..........but then only a small % take the time to tune their bows for BH's which is WAY more important.

Should have clarified, I am NOT going to use an outsert. I was wondering if there was any other methods out there to glue some sort of material inside the shaft itself, or maybe similar to what Gold Tip is doing with their FACT system, if anyone has figured out a way to adhere something to the actual HIT insert itself to get better FOC, as for whatever reason Easton refuses to make a brass Deep Six HIT.

Also, I'm not using FOC as the "prime criteria" when setting up my arrow....I am trying to get a good plan in place prior to purchasing a new bow.
I know what works on my hunting shafts, and am trying to replicate that WITHOUT using an outsert, while still having a micro diameter arrow...no reason to be a d!ck.

Just fyi, even with the Carbon Injexions, 2 deep six inserts PLUS another 40 grains somewhere up front still only equals 14% foc. I'm not trying to build this crazy 30+% foc system. I'm looking for 500 grains + in arrow weight, 100 gr point with 12+ FOC.

If YOU don't want to use micro diameter shafts-then don't, but it makes sense to use the smallest diameter shaft that you can get to fly well. Simple physics. As is a reasonable forward of center %, can't argue either of those facts.

You can glue stainless steel set screws in them but it is a PITA.

Hmm, haven't tried that before I'll give it a shot. I would think that the set screw would act like another insert in that it should glue in well....did you try JB Weld or some other epoxy?

I used hot melt first because I wanted to be able to get them out if the arrow build wasn't working. I then went to gorilla glue. The gorilla glue worked better but still a PITA. You get glue everywhere. They fit so tight you can't hardly get any glue on them to adhere to the inside of the shaft and then then break loose.

Dang! The search continues

What type of FOC are you trying to achieve. The two insert idea seems as though it would be good enough. Also why not use a 125 head?

I would like to be between 12-15%...as far as the head weight, I like Slick Trick and Rage hypo's,neither of which have a 125 grain deep six.. the regular FMJ Injexion meets the 500+ grain requirement, but due to the heavier gpi it's proving difficult to get the desired foc.

I've tried a bunch of different outserts, and haven't been pleased with any of them unfortunately, as that would quash all my concerns, but an arrow that doesn't have concentricity due to the outserts is useless.

If you PM me all your specs, I can build an arorow on my program and provide options. but would need all the specs. DL, DW, Bow, Arrow.etc

I use OT2, I find it to do a better job. I am heading to the gym. Will be home around 1845 MST. I will run the numbers then. Should only take me about 20 minutes.

Sounds good, I will buy that OT2 when I get around to buying another computer, running mine at work now.

Thanks!

Got a great idea from archerytalk- use a finishing nail or headless screw screwed into the 2nd deep six insert for extra foc!
