Add weight to a Judo??

What is the best way to add 50 grains to a screw-in Judo point?

I shoot 175 gr broadheads and I’d sure like my Judo to match that weight.

I see that Alaska Bowhunting Supply sells brass weight that is added to the glue-in insert, but the catalog shows those weights being installed INSIDE the shaft which permanently alters the weight of that individual arrow. I can’t then shoot my 175 gr head on that arrow.

Any suggestions on adding 50 gr to a Judo?

Thanks.

Those internal behind the insert weights have to have an insert that is ‘threaded thru”…8-32 usually is standard, but most aren’t thru threaded. GT’s are, and apparently Ed’s (ABS) are… but likely for their Griz Stick shafting.

Chek to see if you’re inserts are thru threaded.

That is one reason I use brown HOT MELT to affix my inserts. I can sweat them out easily and never had a pull out with the brow hot melt…

Sounds like a project to make a head gain 50 gr.

Thought about the Hex Heads? They get up in weight pretty well. You can always add those wire ‘fingers” behind the screw in point to a Ace (?) Hex Head to help catch on grass and such… fwiw…

Thinking out loud here… or typing out …never mind.. LOL:lol:

A 10/32 nut and two 8/32 flat washers added made mine weigh 177 gr. 😀

I have the brass Griz Stik inserts hot-melt glued into my Griz Stik Sitka. BTW…I never use epoxy so I can remove them if I want.

These brass inserts ARE through threaded but that is not my issue. My problem is that I don’t want the weight being installed (semi) permanent on the INSIDE of the shaft. I want to be able to screw in my broad heads into that arrow. Once I add the 50 gr weight INSIDE the shaft, then the 175 gr broadhead essentially becomes a 225 gr head. Hope I’m explaining my dilemma clearly.

Zwickey really needs to make Judos in several heavier weights.

Good Pat!!!

Now I can have one nut behind the judo for weight and one nut farther back to add misses without having any washers involved. :D:D

Someone needs to come up with something that looks like a blunt of different weights only only drilled and tapped so to screw another point into it.

I guess I’m not explaining it clearly.

The picture on the 3 Rivers site shows those weights are installed INSIDE the shaft. They are screwed into the base/back of the insert and then glued inside the shaft… permanently. I don’t want that. If the 50gr weight is permanent, then I won’t be able to use a 175gr broadhead in that arrow and have it weigh the same as when I have a 125gr Judo on that same arrow. I want to be able to interchange 125gr with 175gr heads on an arrow. If the weight is installed inside the shaft the math doesn’t work. I really don’t know how else to ‘splain it.

Do you have any issues with only catching a few threads?

I thought of something like that, but I wondered if the thread portion of the Judo would be long enough to catch more than a couple of threads of the insert. The nut & washer combo acts like a bushing that won’t allow the Judo to be screwed in as far. Any problems with that?

Has anyone used these for stump shooting? They come in several weights. Do they resist buying themselves? That’s the great thing about Judo… they don’t skip and resist burying.

Seemed like plenty of threads to me. They’ve survived everything except what you’d expect nothing to survive when you hit it.

I have noticed though there are differences in inserts so in some it may not catch enough threads.

😳 No, you were very clear. I just didn’t pay close enough attention to what it was I was posting.

Kind of like a screw-in version of a Woody Weight. It surprised me that something like that’s not readily available.

In an attempt to redeem myself, if instead of using the screw-in judo, you use the glue-on version (135 grains for the 11/32 version) and then use the long aluminum screw-in broadhead adapter (42 grains for the 11/32 version), you’ll be at 177 grains.

But then it would be 2 grains too heavy:roll:

Just kidding. Very creative. Thanks Patrick:)

Just so happens that I have some glue-ons and long adapters laying around.

I know this is not what you’re after, but I build my stump arrows to match the hunting arrow, but leave them as dedicated stumpers. They have heavier brass inserts and heavier steel adapters to make the judos match weight. The reasons for dedicated arrows are that I still stump a little in hunting season, I use these to shoot a few shots into a stump or dirt right before heading into the woods and because I don’t want to subject my hunting arrows to the same abuse unless I’m taking a shot at animal. Best, dwc

Can’t argue with that at all.

I do tend to use the same few shafts for stump shooting but I think I’d like to have all of my shafts (minus the point) the same weight.

I should stress that I’m shooting carbon and I really try to avoid putting heat to the shaft to melt the hotmelt to change inserts, etc and GrizStiks are expensive. I’ve ruined a few while trying to remove inserts with heat… I’d like to set-up the shaft and be able to shoot whatever point I need to. I don’t want to have certain shafts that weigh more than others because I have extra weight installed permanently inside the shaft.

I really don’t understand why Zwickey doesn’t offer Judo in different weights because there is definately a market for them.

Put a washer behind the broadhead and make it 177 and all will be well.. :D:D

Just being ornery. Been known to do that. Have a good evening!!:)

Measure out two grains of glue, and walla! I have the answer for everything. 😆

And you’re welcome. 😉

First, check the actual weight on your Judos. Last batch here of the nominally 135 grain glue-ons ranged from 140 to 148. At 148 that’s nearly a ten percent variance.

I’ve experimented with melting lead shot into the glue-on Judos, but it oozes out sometimes. When it works you can get to around 160 fairly easily, but much beyond that would be tough I think – you run out of room for the shaft.

I’ve just mounted some of the 175 grain glue-on Hammers, which I’ve only shot at a Rinehart 18-1 target backed by a horse stall mat. (They bounce off the target sometimes and they stick slightly sometimes.) I’m waiting for the right circumstance to do some stumping with them, which by the looks of things around here will be sometime in July or August …

for my glue on judo,s I drop a small lead sinker into it so that they are 160 grains
