Would like to know the spine of the Easton 1820 shafts. Tried to find it on Easton's charts, it either isn't there or I'm overlooking it. Most likely the latter, old and blind. Thanks for your help.

They have a deflection of .592"

Aren't those the same sized shafts used for National Archery in the Schools Program (NASP)? The shafts are shot with the Genesis bows.

Spine is 53 pounds.

It puts them between a 1916 and a 2016....about the same as a 2014........

Don't have one to spine. Probably around the same as a 1918. Around 55 to 60#'s I would guess...Van

On my spine meter, 1820 measure .480 deflection on 26" centers -- the old AMO measurement. That's about 54#. As said above, very close to 2014s which are .475 for 55#. 1916s are .510 for 51#. All three shafts should be easily tunable to a bow that likes the low 50# range.

Yes, that is the NASP arrow. With .20 sidewalls they should be VERY durable.

What point insert fits an 1820?

3Rivers sells inserts for 1820's and there are a couple of different sizes of inserts for carbons that will fit also.

1820's are the work horse aluminum arrow around our place.

Easton lists them at .592, 12.2 grains per inch, 354 grains for 29" shaft.

'Comparable' spines are 2013 and 2014, which deflect .610 and .579 respectively. Those shafts are 9.0 and 9.6 gpi.

Definitely a durable, heavyweight choice.

My granddaughter is shooting these in her Genesis bow at her school. The arrows are very durable, I get that, but besides being durable, they are very heavy and too stiff. These Genesis bows used in the schools are pulling 30# or less. I weighed one of the 1820 arrows they use. They weigh 460 grains. So the youngsters are shooting arrows that are too stiff and heavy. Their release has to very smooth for these arrows to fly to the mark.

I'm told that at the short draw length and low draw weight like the Genesis bows spine is irrelevant - not enough paradox to matter.

I noticed in the new IBO rules is that there is now a 'Genesis' class for junior shooters. Closer stakes, 1820's only. They might only do this at major tournaments.

The Genesis 1820 is the only arrow allowed in the National Archery in Schools Program. Also the only arrow allowed in the Centershot Ministries Program. We use them at our Church. Very durable but not bomb proof. Dave

Riverwolf, I found some orange ones at the Academy Sports and Outdoors store here close to me. Thye were finished arrows but I just strip them.

I found orange shafts on eBay.

Fletched them in blue and orange and used a blue Deep-6 nock.

They're an excellent shaft. I cut them to 28" for my 27" draw and use them on 48-53# (at my draw) bows.

How easy are the genesis points to remove? Methods? Thanks

Heat, they come right out.

Depends on what you glue them in with. Most people use hotmelt so it's pretty easy.

My Easton chart says static spine at 28" is .530; at 29" it's .590 and at 30", .655. Keep in mind my chart is from their 1968 chart. :) It still works just fine though.

I bet they would blow thru deer.

We will find out this fall, I hope. Love them, have 300 grains up front making a 28” arrow 600 grains or so. This combo is shooting great out of 32-37#. They also still shoot great with 200 grains up front.

On my Scheib spine testor they are 53# spine at 28”.

Might want to weigh them again. I’m playing with some now, too. 28” with 175gr tips weigh in at 545 grains.

Aren’t the genesis bows cut so far past center that it’s virtually impossible to be overspined?

If I wanted an arrow that heavy, they’d be on my short list. Oughtta penetrate like a shaped charge!

My digital scale says 618 grains to be precise and these are the old green Gamegetters with glue on nocks. The bushing for the press in nocks I’m sure weigh more.

Yeah, I have the new ones

Yeah, I have the new ones

I heated one up last night pretty good and couldn't get the tip to come out. 3Rivers said that Easton uses epoxy so they will be hard to remove. I was hoping to leave them at 30" so I may end up buying shafts.

Pulled the nibs out of a few dozen. I just put the flame of my alcohol burner on the tip for a few minutes, then grab the tip with a set of side cutters or good needle nose pliers and out they come.

Can anyone tell me which nocks will fit directly in the shaft of a Genesis 1820 without using adaptors?

And which point adaptors fit the 1820 for using screw-in points?

N or X nocks.

9/32 screw in points or I use those from VPA and 3 Rivers that have the back edge tapered down for easy removal from foam targets because I can get them in heavier grain weight all the way up to 300 grains.

Caboo, I sent you a PM

Some .244 nocks will fit directly in 1820's with the nock bushing removed.

That's how I prefer them because I don't really like the tiny nocks that fit in the bushings.

I know that Easton super nocks and Carbon Express launchpad nocks will fit directly in the shaft.

I've tried Bohning signature nocks, but they're too tight.

3 Rivers sells the screw in point inserts for 1820/Genesis shafts.

Kelly - I believe the N nock is for using with the uni nock bushing. Of all the press in nocks on the market for carbon arrows I would think one would be of the correct diameter to press in the Genesis shaft WITHOUT using an adaptor. Also looking for screw-in adaptor that will fit the inside diameter of the Genesis not screw=-in points.

Thank you Recurve Crafter!

Thank you Recurve Crafter!

Where are you guys getting 1820s?

"Where are you guys getting 1820s?"...Lancaster Archery has them.

Like fdp saiid, Lancaster Archery has them for $3.92 for each bare shaft with nock bushing. Most popular colors of shafts are not in stock.

"Most popular colors of shafts are not in stock."...I wish they would start making the orange 1820's again....

“I wish they would start making the orange 1820's again”....….??

I heat mine up with a propane torch. Just put the tip in the flame for a second and give it a twist with vice grips.

When I was looking for inserts I had some discrepancy in part numbers with Lancaster. I somehow figured out that PDP made the inserts and I called them. I think I talked to the owner. His first comment when I said I was trying to make an 1820 genesis work as a hunting arrow was "That's a great choice."

I think he said he may be working on some heavy weight field tips to go with these, or maybe even another insert material. Either way PDP seems to be a stand up USA company and the guy I talked to was a great fellow.

I think the ID of these is .234 ballpark. I purchased .243 (I think) brass inserts and just hit them with a little sand paper with the drill. This gets them down small enough to fit in the Genesis arrow.

I think the Genesis shafts are a great economical choice up to 50 Lbs. I did have to back off of the tip weight with the higher poundage and haven't taken a deep dive on the tune, but I'm guessing something in the neighborhood of 175 grains total.

With around 40 lb bow I was running about 250 grains out front.

Genesis can be found over the counter at Academy Sports if you are in the south.

Also for a State Championship NASP shoot (atleast the state of Alabama) the kids who participate for a $20 fee get a T shirt and a set of arrows to compete with. The arrows as I understand it are theirs to take home. I bet a fellow could go to one of these shoots and buy arrows off of people as they leave on the cheap.

“ With around 40 lb bow I was running about 250 grains out front.”

Holy CRAP!

If that’s what it takes to get it tuned, then I guess that’s what it takes… But you’re talking about a 600 grain arrow… I don’t think I could talk myself into 15 GPP, but personal preferences are indeed personal…

ID should be .242, right?

Man I have a 47# recurve that likes to shoot full length 1916s with 200 gr up front. I would think that would be weak but they fly great. The narrow shafts penetrate so well. The 1820 would be crazy, but probably heavier than I would prefer. But tempting.

The large groove G nocks will also work and fit my 12 strand D-97 with .021 Halo serving perfectly. Also works on 12 strand B-50 with .019 Halo.

Was just shooting some tonight out of my 30# R/D longbow. I know they should be too stiff but fly very well for me with 250/300 grains up front. My 27.5” bop 1820 with 250 up front weighs 618 grains. I know that is 20 grains per pound but with a 6 strand SBD Psyco string they shoot amazingly and the string is super quiet without any silencers.

FYI, 1913’s and 1816’s with the same 250 grains up front fly very well, too and are over 500 grains.

Majority of my hunting shots are 15 yards and under so am not worried about trajectory. Rather want a heavy, skinny shaft that packs a punch behind my very sharp broadhead. And when putting together my hunting shafts I replace the screw in insert with the old one piece glue on broadhead adapter.

I'm not sure if I will hunt with these or not. I have chronographed these at 135 fps out of my 40lb Ocala. I'm really just learning at this point.

I'm a cheapskate and these arrows are a great option for the money.

I weighed one last night.

Frank, how long is your draw?

Are you using these full length?

Yes full length. I started with full length bare shaft and went up in weight until they stuck in the target straight. I'm really just getting started and doing a lot of learning.

I have not shot this arrow bare shaft with over 40#.

I took the 200 grain tip out and replaced it with 125 and they shoot OK to the eye (I haven't looked at them in slow motion) with a 50# recurve. I'm still trying to decide what I'm going to hunt with. I will likely try to to tune them to the 50 lb soon. If it will even shoot well bare shaft. May be too soft.

With the 40# bow I am tip on at 20......

You haven’t said what your draw length is?

Do you rely on the longer length for point of aim?

How much do those brass inserts weigh?

Am sure they’ll shoot fine out of your 50# bow, which apparently they already are, might have to shorten them a bit to bare shaft. But you will gain extra spine back with four fletch.

FWIW, the 1820s aren’t the only game in town for bargain-priced alumalogs…. The Jazz series comes in a very useful range of shaft diameters, all with .016 wall thicknesses.

Especially if you’re new at all of this stuff, I would take a solid recommendation on shaft and point weight from one of the Old Pros here (please provide actual draw weight at your DL and desired arrow length) and go with that, rather than trying to force-fit the Genesis shafts at 15+ GPP….

Something like a 1716 or 1816, let’s say, unless you really want that 20-yard point-on…

I’m also less inclined to recommend bare-shaft tuning than I used to be, mostly because it was a long time before I got good enough to prove to myself that I should have stuck with the first Old Pro recommendation that I got, instead of all the stuff I tried along the way….

I'm in the neighborhood of 27 on draw. I haven't measured lately, and I know I have made some changes since getting started.

Inserts are 50 grain carbon express .244, and I believe they make 100 grain as well. Lancaster. I do have to turn them down about ten thou to get them to fit inside the Genesis shaft.

So are you taking into account those 50 grain brass inserts on point weight?

They make aluminum screw in inserts for these shafts. They are much less in grain weight and won’t decrease the spine as much.
