Guys forgive me... Part of this I'm still learning... When I was young I always just grabbed some arrows from the shelf and had the shop guy cut them an inch longer than my draw and go with it


Are there any tutorials or step by step show to foot a carbon arrow

#2 is it necessary

#3 does footing change the spine - i.e. Do I need to account for this when bare shafting

These arrows will be used for everything from turkey, whitetail, elk and now caribou...

I'm kinda wanting to get everything set up and be content with it and leave it that way to practice all summer

Yep.  Here's a good one for you done by a TradGang member.  It will save your arrows from being destroyed by making them Much tougher.  You will not go through nearly as many and you will save a lot of $$!!!   Others will chime in with their experience.

In this video Daniel is building arrows for stump shooting.  Basically shooting at trees!!   There is more info than you asked for but he does show you step by step how to do the footing.  Hope it helps.

Yes, it's worth it.  No, it doesn't affect spine that I have seen.  My footings do add 20 grains to the front of my arrows, so take that into account when tuning.  

I shoot fmj's footed with Big Jims "arrafoot" kit.  The added durability will literally blow your mind.  If you shoot a lot, especially a lot of stumps...I can't recommend them highly enough.

I foot all of my carbons. Don't forget to foot the nock end too. It will keep the en from splitting when you hit something hard.

if you want to use aluminum shafting for footing check out charlie lambs post in the how to forum
good luck

Yup you better foot both ends
