Nock Fit

[Scattergun2570]

My bow string was served to fit a Classic nock by SBD. I was thinking of trying Heritage arrows,but now the nocks will be different. Do you change the serving to fit,or do you somehow adjust the nock,sand it to fit? Thoughts and suggestions please..

[JEFF B]

well  for me if a nock don't fit i sand it till it does as i sure don't want to re serve to make one fit just my 2 cents worth

You will have to sand them to fit,the Bohning Classic nock has a pretty large throat when compared to most push-in type nocks.You might try some Easton 3D Super nocks,they have the largest and deepest throat of the push-in nocks.The 3D Super nocks are different from regular Easton Super nocks.When I'm making up a string for my bows I like to try to get the serving diameter to .108 to .110.That diameter will fit 3D Super nocks and large groove G-nocks great which is on most of my arrows.But the Classic nocks have a larger throat.If the 3D Super nocks are to tight,you will have to sand or reserve to fit.I use to sand my nocks but I have enough different diameter servings I can just serve to fit.Some guys will warm up the nocks in hot water and then fit them on the string,but that seems like more trouble to me then just serving to fit.

i have had luck in dipping them in very hot water to soften...put on string and fit and let cool.....I only put the two prongs and throat in water....I dont get it up to the collar of the nock where it would let hot water seep past the shaft.

to me it is much simpler than reserving or sanding.

Bring some water to a slow boil.  Stick the nock in the water (nock only) for about 20-30 seconds. Then place the nock on the string and wiggle it a little.  Let cool and your nock will be good.  Same thing if it's too big, gently squeeze it and it will get tighter

I shoot CX Heritage 250s with Bohning Classic Index nocks by using a nock adapter that glues into the shaft.

I know 3rivers sells them, but I'm sure other sponsors do as well.

I hope this is what you were referring to.

All good advice above.I also recomend the Bearpaw classic nocks.

I do the exact same thing.

GT traditional nocks fit perfect on my SBD strings. Bearpaw classic nocks are too tight. I have a little file, that's exactly the right size. So I file the nocks and then they are perfect too.
I found out that a good nock-fit (read: not to tight) improves your shooting a LOT! This is highley underrated.

[Brock]

as per my post had to adjust some classic snap ons...too large for the 12strand FF that came with the Mohawk Sparrowhawk.  just before water boiled removed....put in shallow dish....inserted nock for 15 seconds...clipped to string....squeezed ends together, snapped off string then reattached and let cool.  Did a couple of them in 30 seconds.

went out and shot and big difference in security on string without being too tight.

Has anyone tried the Nock-Tune™ from 3R?

[Brock]

I have not tried it but only works for making your nock throats larger...if you have a snap on or nirk nock with 12 strand or less FF...will need to close the nock size not increase.  It does appear to be a great way of opening up the throats on some that are too tight with its 6 different filing blades.

I personally reserve and dont recommend heating or sanding.  

heating can distemper the plastic making it brittle (especially in our cold weather).  It will also weakn the glue joint if you're using glue ons.   Too many chances imho!  it can and does work...and it only takes one failure and you blow a bow up or worse!

Both can be sanded/heated out of alignment costing your accuracy.  

Serving is simple and can be manipulated to get good string/nock fit.   Extra strands/dental floss/double serving or combinations there of.

[giff]

I do the same as AKDan. reserving doesn't take that long and I have 100% confidence in my gear. just last week I reserved one with 2 layers of floss underneath. now I have the perfect fit, and know that if i break a nock, I can replace it and it will fit without any modification.

I have played with using a nail file/emery board and that has worked.  Also, if you figure out just the right "give" point, you can actually just bend em open with the edge of a knife/spoon without breaking them..and there is a sweet spot where they will bend but not stress the plastic (you might break 1 or 2 figuring out that give point haha) and they seem to stay where you need em, heck the other day I tried some new arrows and just used my teeth.  The newer plastics are tough but still have a lot of bend potential, especially the solid colors, the translucent stuff seems to break more easily.  LOL.  Tried the hot water thing too and it works.  

The emery board seemed to be pretty quick and able to fine tune and is the method i prefer.

[surething]

I like too use one of the wifes emery board,
thethick style, then you get both inner sides at the same time and only takes a few strokes.

I agree.

[gordydog]

I've used the hot water trick with great success.  Doesn't need to be that hot to work.  Great note you guys mentioned though about wrecking the plastic nock integrity.

I just use Easton super nocks in all my carbon arrows of 5/16 diameter when the factory ones don't fit my string.  They are  indestructible and easy to spread open or closed to fit. I also swap nock types around when I get a used bow with a string a different diameter than my typical ones.  They all get used sooner or later.
