You might be able to foot them with a short piece of aluminum shaft.  Just a guess I've never tried.

You need to buy an arrow streacher bro...

You can find em at any auto parts store right next to the blue muffler bearings....

Kirk you are behind the times...blue muffler bearings were replaced by the new and improved taupe version in 2010

The think to remember is that henweighs in Canada are metric now, same as the muffler bearings...it can get pretty confusing

When I find my arrows are too short I just put them on the saw and cut them longer

no safe way to make them longer, unless you want to put a overdraw on the bow. Then your arrow may still be used...

Fujimo  now at first I too was thinking "What the heck this fella's been smoking" like some other's are funning you about but then it had me think "What if a carbon was cut short" and the only thing I can come up with would be to take a aluminum shaft and epoxy it as you would a footing but leave an inch over and use a aluminum insert that fits that aluminum footing/shaft...Just have to re tune that's for sure...Sveltri had an idea there with the footing and I would say glue on the insert for the aluminum first then cut the amount you need for the carbon and epoxy it on last...There was a chart here that used to show exactly what aluminum shaft fit over carbons but I think you can make that arrow longer...

keefer's right.

using the end of an aluminum arrow (2117 for 1535s and 3555s) the insert for the 2117 is just about 1". If you cut about 2.5" off a 2117 arrow with insert already installed you might be able to get something shootable for your draw. Then cut 2.5" lengths and add 2117 insert first then epoxy onto the carbon shaft.

Another way to add 1/2" or so to what has already been mentioned is to install gold tip nock coupler/adapters to the back of the arrow... Remove nock, push in nock coupler/adapter, install nock... It will stiffen the arrow some but it's easy. Just a thought.
Title: Re: how to lengthen carbons
Post by: ChuckC on January 13, 2014, 09:24:00 AM
There are ways. . .  but likely, it would be best, and cheapest (and maybe safest) to just buy a half dozen new shafts and start over.

You can also have some custom made tip inserts made that stick out in front of the arrow a few inches.

Sounds like a ton of wasted time and trouble.  If they are new, post em for sale, at half, move em, and buy new ones and start over.

Post by: SELFBOW19953 on January 13, 2014, 09:41:00 AM
Ask around, offer to trade on the Arrows and Arrow Components Forum.  That's the safest way.  I would only use a "spliced" carbon for a one shot situation-hunting-where you expect to loose it.
Title: Re: how to lengthen carbons
Post by: fujimo on January 13, 2014, 09:43:00 AM
right now the shafts are at the new uncut length!!
they are just too short for my draw length- maybe i should just stick to the woodies.   :dunno:  
maybe the nock coupler is a starting point, then see about adding to the front.

have been tuning using point weight- not cutting.
thanks fellas

Sure glad your a good sport! We have been funning with you, but basically it's because there's no real good absolutely foolproof way to do it that I know of. What is your draw length and which model and size of Goldtip arrows do you have? Most of their models are 32" long I thought. I have monkey long arms and have a 31" draw, I understand your pain and have been in your shoes!

I would be worried about the shafts spinning true with a footing and insert.

I think I remember a guy making some take down arrows by cutting the arrow in half putting a standard insert in each half of the arrow at the new cut.  Then take a threaded piece of all-thread or a bolt with head cut off and thread it into each of the new inserts and turn each half of the arrow until they tighten up against each other.
Same concept could be used to lengthen I suppose?
Title: Re: how to lengthen carbons
Post by: BRIARS on January 13, 2014, 06:31:00 PM
I think the aluminum footing would work fine. If the insert bottoms on the carbon it should add strength to the carbon. I would not hesitate to try it if I was in your position.

I was thinking the same thing.  A lot of trouble to go through, but it would work.
Title: Re: how to lengthen carbons
Post by: TxAg on January 13, 2014, 06:52:00 PM
Also, I've heard of guys using very long aluminum footings, so you could do something similar....3" over existing arrow and 3" over a cut piece of carbon. Epoxy it together and now your arrow is 3" longer than it was. The new piece of carbon could be cut so that it's flush against the old piece and the point end already has the insert glued in.
Title: Re: how to lengthen carbons
Post by: xtrema312 on January 13, 2014, 08:55:00 PM
What are your shafts?  Best bet is to sell them and  try a different shaft.  If we know the shaft we can maybe recommend a similar spine that comes longer.  I know for instance that GT3555 have run short where a CE come longer.  

Probably a slim chance getting an idea fit for the aluminum footing. Most shafts I foot have the aluminum a hair big so wouldn't make for the straightest arrow.  I guess you could us a slow set epoxy and try and spin test, but I would jut get different shafts.

I have some 400 bemans that I did this exact thing to. I used hot melt so I could twist the footing to get them to spin true. I glued the insert in the footing and then slid the footing over the carbon shaft until the insert bottomed out on the carbon shaft.

I do agree that I would try to sell them and buy new shafts that would work...

oh i dont mind the joshin'
gotta laugh at yourself before  you can laugh at any body else- and boy.... i laugh at( and sometimes with!) a lot of people around me.
this place is like home. i grew up in a boarding school, and spent time in the south african military- cant get tougher than that!

my shafts are 3555's, and as i measure the shafts, they are 30" long.
i have a good 29.5' draw- they are about an inch shorter than my wooden shafts.
ihave two dozen- one- is still in the wrapper- the other has been opened and they have white wraps on them-only 4 are fletched- one i have shot about 50 times the other three not at all. discovered the issue early on( oops- nearly wrote that i had discovered the issue with length early on....   :eek:   - but then that would have been lying- dunno watcha talking about!!)
so quit using them for the hunting this weekend and went back to using the 'woodies'   :D
Title: Re: how to lengthen carbons
Post by: fujimo on January 13, 2014, 11:01:00 PM
maybe i should try and sell them-
what would you recommend.
i shoot 50#- would love to keep the arrows full length if i could! and tune with tip weight if possible!

What is your actual draw length
Title: Re: how to lengthen carbons
Post by: Sharpster on January 14, 2014, 07:15:00 AM
I must have at least a dozen carbon shafts of various brands that have been lengthened by up to 2". Never had one fail and I shoot alot. Believe it or not, I even miss from time to time (very rarely mind you).  :readit:   and have hit roots, dirt, rocks etc with most of these shafts at one time or another. No structural failures to date.

I'm sure some will disagree but if you only need to add an inch, a 2" aluminum external footing with an insert will add 7/8".

I install an insert in the carbon and file the lip flush with the outside of the shaft.

Then overfoot with the 2" aluminum so that the base of the insert in the aluminum footing is seated tight against the insert in the carbon.

You might try making just one up and torture testing it before selling your shafts and buying more.

Cut the too short end off and glue it onto the other end of your arrow....

Post by: zipper bowss on January 14, 2014, 09:10:00 AM
The arrows I hunted with this year were 1535's that I cut off for Tracy. She switched arrows and these were just laying around. They were about 2" to short for me. So I cut a piece of carbon arrow to lengthen them. Then footed over that with aluminum arrow and used the insert in the aluminum to screw my broadhead into. It made those 1535 act MUCH stiffer as well. My footing ended up being about 5" long but I think you could get away with at least an inch less than that.
One thing that confuses me a little though. Is how did Tracy get new new Easton arrows and I ended up shooting her rejects that I had to use a board stretcher on?!?     :knothead:

Check with Big Jim. I think the new 3555GT Trads are now 32" long.

Sell the others. But if in a pickle I'd extend with the footing and see what happens.

Post by: Sharpster on January 14, 2014, 10:09:00 AM
External footings in general go a long way in improving the structural integrity of the business ends of carbon shafts. Thanks to our friend Daniel Yononindo for the test and video:

I've  aluminum footed with aluminum for my stumping arrows as indicate throughout this post. A 2 1/2. - 2215 footing with insert over a 2016 shaft It added 7/8 of an inch. Arrows flew well and were much more resistant to front end bends as aluminums normally are. It took a hit into a frozen log to have the footing fail and then it did not bend. I want to say the footing added 25grs but I'd have to re weigh them. it gave a new life many of my discarded arrows.

I would try one or two arrows and see how they work for you.

Fujimo,

well, maybe not wasted.  How about just using them for shooting small game.  Get some glue on judo's and glue them onto full length aluminum or steel adaptors.  That should give you a little extra length for clearance.  

Or, instead of using screw in adaptors and some sort of insert, getcha some of those brass inserts that are the insert and adaptor all in one, and still use the judos.

If you use large 5.5" fletching you can get away with a lot of non-tuning issues, and just enjoy them for what they are.... a learning experience and bunny arrows !
