I want to build some dedicated stumpin' arrows and will be using GT 3555 Exp. Hunters and Trad arrows. What size aluminums do you GT shooters foot your 3555's with? What type epoxy? I have JB Weld and Devcon 5 minute epoxy already. Thanks.
I think 2117's
I used 2117
I have only used Epoxy and it held up well.
The Devcon 20 minute set, 2 hours handle, overnite cure type epoxy has always done well for me.
2219s have worked well for me as have 2117s, 2219s seems a bit better fit. The long curing epoxy is not as brittle when it sets up and seems to hold up better for me too! Shawn
2117s.
I used 2117 shafts and they are smug!
Only thing you have to do is sand for 5-10 seconds with 400 grit sandpaper where the footing is going to get a rougher surface, smear a thin coat of epoxy and slide it on!
Also, I like to leave a little epoxy behind the tube to get a smoother transition between the carbon and aluminum, which makes it easier to pull out of targets.
Also, it can be smart to deburr the alu slightly ;)
Good luck!
Im doing the same thing with 3555 and im bona use. 2117s
2117's
Why not foot them internally? I use a 4" long .25" wood dowell epoxied behind the brass insert.That way I keep my small diameter for penetration!
Seems like alot of people workin' up stumpin' arrows this Spring (Myself included!)
2117 seems to be the ticket for GT 3555's, although they do seem a little snug to me.(Perhaps a little shaft sanding as Svein D said)
Never really considered an internal footing for stumpin', not real concerned w/ penetration, just tired of bustin my arrows on hard hit.

Nontypical, does it change anyting on how the arrow flies.
My luck with internal footings had not been good, the point still shove up into the shaft and splits it, the wood dowel also adds quite a bit more weight than an aluminum footing as well. Shawn
Was going to ask this same qeustion. Good thread. Also: Shoudl the end of hte aluminum cover (OR NOT) the insert?
thx in advance

Has anyone tried using the 50gr brass inserts instead of footing? Once I put the brass inserts in I haven't had a shaft mushroom on me yet.
2117's
I use 50 gr. brass inserts on most of my set-ups,(GT trads)for some FOC. Before footing, a hard hit, when stumping or just plain missin' would sometimes produce a real nice "flower" on the point end of my arrow shafts!
So now I am footin' all my stumpin' arrows w/ 1-1/4" of 2117 behind my inserts. Just my experience, YMMV.

I use the 100 gr. insert and still had some Flower out. I also use a 2216 over the insert and up the shaft with high impact instant gorilla glue.
Inserts wont stop the shaft splitting. I haven't tried internal footing, but in my brain that does not prevent it too much either, on account of the force of impact pushing the insert back, making the more brittle carbon "get out of the way" outwards.. Then again, I can't say for sure..
The dowell weights 25 grns and doesnt change anything.I also use 50 & 100 grn inserts.I have NOT had one break yet and people that know me & Jose at 3D shoots,do some crazy shootin!! The first test I did wit them,I shot a patio block and the third arra broke it at 15 yds.Only thing that happened to the arras was the pts were flattened.All my arras I use loctite prof. HD 5 min epoxy.I wont shoot carbons without it!
SveinD, the epoxied dowell will not let the insert push back against the shaft,aiding in it not splitting.What I do is put epoxy up inside,I then coat the dowell also,I then push up and leave .125 of dowell out,coat insert,then wit insert push the dowell the rest of the way in.Now they are tight,back to back,leaving NO space for movement.
Well, I just finished a couple of arrows. I used a 2 inch piece of 2117, should weigh about 24 grains. I did have to sand the 3555 Trad arrow with some 120 grit paper to get the 2117 shaft over it, good tight fit. The 3555 Expedition Hunter required no sanding at all, I just barely ruffed the carbon shaft with the 120 grit to knock the shine off. I'm not going to fletch these shafts yet, I want to bareshaft tune with a 150 grain point instead of the 175 grain and see if arrow is still in tune. Has footing an arrow caused anyone to have any tuning problems?
2117 will work.

30pointbuck.....thanks for the link, I have some Heritage 150's that may need some footings at some point in the future. Anyone ever foot the CE Predator II 2040's or 3050's? I have a bunch of these arrows too.
well i finished footing a couple 3555s for the first time today. I used 2117 at 1 inch long and they turned out pretty good, just be careful cutting them if u dont have an arrow saw. I used a dremmel tool and almost got hit in the face with a piece of the arrow i was cutting
I used a mini tubing cutter, works great but slower than the Dremmel.
Matt Green beat me to it.How long should the footing be?Just past the insert?An inch past the insert?Give us newbbies a clue.
Oops!I posted this b4 I realised there is two pages to this thread.

I'd love to see a build-along of that :)
Been using a 1" piece of 2117 on all my G.T. Trad 35/55's for some time, 12gr. extra weight up front but short enough to not stiffen the spine any & after it's all said & done mine at full length spine out just right for me & are also near bomb proof.
Well maybe not bomb proof but I've yet to hit a rock or concrete wall with em & have any damage to my arras.
