We need to help Airgun Designs find a source for the bike grip rubber.

The foam stuff is embarrassing to us the mag community.

Anyone got any ideas ?

Lets go boys !

I use Jonal Laboratories at work for various rubber applications. They are not cheap, but they are high quality.

I definitely prefer the rubber over the foam. However, my top choice is simply a hard foregrip -- aluminum, carbon fiber, etc. There's no foam or rubber on X/E-mag battery packs or the super-majority of aftermarket foregrips.

There are so many nice bike grips out there. Trouble is the length.

Nothing wrong with the actual foregrip, what they need is something worthy of an Automag besides the cheap looking foam.

Looking at the SandFX markers is what got me thinking about this, the foam doesnt belong on those markers at all....

You know there are several companies that make new frames, I really like what Ruff Cycles makes. You can relive your youth with a sweet custom bike. About 15 years ago I had a custom frame made, I sold it about 5 years ago while moving and regret it. Someday I'll get another one, this time it will be easier to ride. The one I had made was over 8 feet long and I had to lean way forward and had my feet almost diagonal to my torso in an ackward sideways U shape.

Unfortunately we have tried to find a manufactured grip that fits and is obtainable in small quantities.
Have been unable to source such a beast.
Honestly even the foam will run out on us soon enough and I'm not sure we can reproduce that length in small lots anymore either.
Everyone wants 2500ft minimums....

I'm still looking. I've bought several bike style grips to see if we can cut them...but it hasn't really worked out.
I like the idea of a CF cover but the vertical grips we have are cut too narrow in diameter for a sleeve.
We would have to sleeve the sleeve.

I've also considered just getting more grips from Luke. He can CF sleeve his. But then everyone is already complaining about the price on custom guns.....so that's pretty much a bust.

Everyone keep looking!

Evil! make a mold!

BTW Luke, I love that Bike!

Tim, they would be hard plastic, not rubber, but they would match the texture and look EXACTLY like the original. I will have to research how to do a mold like that, but I'm sure it can be done.

If a compatible rubber bike grip is proving dificult to source and since these would likely be low number runs of parts has anyone considered designing a new, dare i say improved (if possible) rubber bike grip style handle and have the injection mold made from plastic using additive manufacturing (3d printing) and mold the parts using a mechanical injection press. The mold would be significantly cheaper and quicker to make. Since it wouldn't likely need to cycle thousands of times it would allow AGD to play around with a few different designs/color runs if the demand was there for such.

Food for thought.

Before making a mold BE, I think we should probably exhaust all other possibilities.
I did get a response from the grip company, but I need to get them more info.

A 3D printed mold is a good idea. Have to source who could do the injection part.
Both those idea's are above my pay grade...no 3D printing experience or injection molding experience.
It seems like a plausible idea though.

Keep any idea's or sources coming.
Thanks!

I would just use the original bike grip that AGD offered and make a rubber mold. Materials are readily available, cheap, and can be purchased in small quantities. It could be a pour mold or with a little imagination you could even do a poor mans injection mold. The following is only meant as an example in how to make a rubber mold not a design idea for a grip, I also left out the gates in the mold. The mold and the grip can be made out of rubber, the mold could be made in a few hours, the grip can be made in just about any color.

The RPG Stick Grip was a re-anodized RT Pro Gas-Thru with the AGD Bike Grip grip. I purchased what I believe to be the last of AGD's inventory of those years ago. Whats out there is all there is, unless someone else intends to make more.

Sandman

Of course the original grips are all gone. If they were not, I'd be using them.
Luke, I like the mold idea , but whose going to make that mold?
If the end product is going to have any quality I can't see how a 3D printed mold would work as they are typically not very good quality.
3D is great to print a mold prototype, but the actual mold...I don't see that. At least not from my limited knowledge.

We are better off finding someone with the mold already.
I am still trying to locate the original mold as that would obviously be the easiest, but no luck yet.
UPDATE: The company is out of business. So no original mold to work with.

A mold that is close and can be masked off would work too.
Crazy how what seems to be something so simple is really not that easy to procure.

If it was metal we could do it!

You can probably make a soft rubber mold of the AGD Bike grip for less than $50

I have time off the next few weeks I can experiment with the mold idea.... I have plenty of those things laying around and could sacrifice one if need be.

The only issues I would foresee (other than being able to successfully mold one in the first place), is that the copy would be hard plastic, and that little lip that keeps them on wouldn't last long. Also, there will be a parting line where the two mold halves come together. May or may not look bad depending.

I have created parts like this for my job before. The easiest way we found to make parts was to use casting silicone in a pvc pipe with the part in the middle. Then we just cut the silicone mold in half and ouila, you have an exact mold copy. You insert the grip into the middle of the mold, use something like a female 1/8 npt fitting to keep it centered always, then slowly pour your urethane in. If you mixed it right there are no bubbles. If there are bubbles a vacuum chamber can take them out. After it cures, pull mold out of pipe and split in half. Preinstalled perfectly molded bike grip. Urethane can be ordered in any durometer you want so you can have a very hard or very squishy grip.

The trick with castable Urethane is degassing it like you said. There are a lot of good products out there that do not require it to be degassed and that cure very durable. The downside is that you loose some of the options regarding durometer.

Every other marker in existence uses a metal regulator as it's "foregrip." I would design something aluminum that would screw into the existing vertical adapter. Make it compatible with the Exalt grips (or include one) and call it a day.

This is really a good idea too. I"ll have to check how deep the inventory goes on vert grips. Would be nice to make something compatible with product already made.

I'll check with Allen PB. I've used them over the years for product. They made my first "Stopper" barrel plug.

For a non originalor at least a general, non-specific grip you need to find something that works with in the design that is complimentary. The original RT i liked as you could flip it to be finger in or out.

Realistically, you can not find on design that would liked by all. At most, finding something that works, that is inexpensive and can be easily sourced is hard enough. Having options is ok, till you find the one person that doesn't realize that A, B, & C are the only things. Its fair better to narrow down the options in simple ways, like: hard(like the AGD single hole grips), soft or somewhere in between; then go from that.

Yes and yes! I had been drawing up a front grip that would utilize Exalt's Luxe grip - super comfy! Unfortunately my Solidworks licence expired and with it alot of my lofty Mag dreams. Still, a grip that used the Luxe or Shocker RSX rubber would be great (along with some matching Exalt 45 grips?)
You would expect Exalt to be eager to collaborate as it would mean more sales of a grip that is otherwise proprietary to one gun...

They suggest we buy what they make and cut it, but offer no advice on how to do that well. I also checked with one of the other top rubber grip companies and they straight up blew me off. Showed no interest at all other than buy what they have off their shelf.

So the whole 3D printed mold thing with the proto putty stuff is pretty cool. Not cost effective at all, but maybe a cool way to make a custom grip.

Cheap injection molding with a 3d printed mold. Sounds good too. I just have no clue where to start.:confused:

Do you have a sketch/ picture/ model file of the outside grip pattern that you had in mind? This would be a good place to start and look at how moldable the design would be and move on from there.

Nobody
10-26-2016, 04:09 PM
In my limited experience, my understanding is that most companies that do any mold producing/rubber parts, literally want thousands upon tens of thousands of product, in order for it to be "worth there time" to get a piece that is bsically cost effective. That being said, to get a grip of say 2000 units, it could cost .50 dollars per piece, but a 10,000 unit order could be priced at .10/unit. So to get something that was like before or a newer grip is not cost effective, nor having a huge stock that AGD would take years upon years to get rid of.

So there are 2 options. 1) reuse a source of preexisting grip, i.e. the cut and fit grip. 2) use a grip that someone else has made, say the PE front rubber on the latest Geo and design a foregrip (with permission to use and source the rubber) a grip that uses that design. You can then order as needed, not have an investment in the molds, products, and storage.

And here is the rub. You can not please all the people all the time. Someone has to make a decision on what and where to go and stick with it. Majority rules and sometimes having just an option is better than not having any choice at all.

Soooo I'm an AGD/automag noob, so pardon me for asking. I'm assuming from reading that the goal here is some sort of foam/rubber padding to go over the gas through/foregrip, right? Is this endeavor a "classic" or nostalgia thing? I can only speak for myself, but I'm also looking for the ideal foregrip. Right now my current set up is the stock Mini vertical adapter with a Kermode Concepts ASA extender. Adds about an inch and a quarter to the vertical adapter. Looks good kinda old school, but not CNC'd like everything nowadays, which I actually like for the Mag. Keep it simple. ...I have a vinyl plotter at work, and I was going to simply cut some simple finger grooves/patches out of Talon grip material. I for one don't like TOO much grip. If I had access to the proper tools, I'd make one long vertical adapter, about twice the length of stock (or whatever length). I'd machine rectangular shapes into it similar the Magpul Pmags, and then put Talon grip material into the recessed areas. Hexmag does the same basic thing....and I know how you guys love your hexagons! LOL..... .....but seriously, with the tools and know how at my disposal, that's what I'd make.

That sounds good. I like the idea of using existing AGD foregrips and sleeving them with "stuff". A young monkey showed up on MCB that was blowing/blending glass. I was trying to get a grip cover out of him, but I think his class is finished now. Oh, well, maybe somewhere else. :)

With a couple of little end pieces, you could make a little "carbon kit" of CF tubing and ends that convert the old AGD grip to CF of the right diameter. Might need a little set screw the bottom piece, if there's nothing more creative to hold it in place. I kind of like that idea. :p

So my first try kinda worked; that Oogoo stuff is a little harder to make than it appears. I overshot the handling time.

I went for a 1.25" OD grip 7/8" ID and 3" length. Still not sure if those are the correct specs, but this was all experimental anyways.

Aside from mixing the Oogoo the hardest part was rolling the pin across the pattern -- I slipped a lot, hence the backside is all mangled. It's usable, but somewhat malformed.

If I were going to make a real attempt at this, I'd make the roller/landing a rack-and-pinion and then the two would be in lock step as I rolled it across each iteration. And maybe a few other tweaks.

So that is what, corn starch and silicone ?

How expensive is it to make amd how well would it hold up ?

You could make swirly colored grips, but that might start trouble.:rolleyes:

Silicone ($5 for a large tube), corn starch (cheap). I also used food coloring, but I wouldn't recommend that as it is an active part of the mixture. Especially when it contains glycerine. Better to dye the grip afterwards. And nitrile gloves. Left hand still smells like vinegar...

It seems very durable after it's set - much like a heavy rubber.

And yes, I imagined people getting really fruity with the coloring scheme. That was kind of the point. This isn't suitable for mass production per se, but grip preferences are so subjective that they might as well be custom jobs. (And you're paddling up Smith creek if a traditional (American) manufacturer doesn't want your work anyways.)

It'd be nice to have an off-the-shelf rack+pinion to keep the rotation synchronized.

But maybe the next easiest thing would be a GT2 belt. 3d print the toothed roller ends and glue the belt to the table.

Anyways, just something to think about. I don't even own one of these grips in the first place.

I didn't study it very close but you may find something here, or contact MMC for further leads, they're pretty good about answering their phone. ;)

#'s 3 & 8 look like they'd be perfect. really sad that #5 only comes in 1.25" ID. And you can get #8 in black, red, or white.

good find, Luke.

the question is what is everyone willing to pay for the replacement grip? $10, $15, or $20. i've got a friend that works in a place that does cast urethane products that says they should be able to do it no problem. they make their own molds and he says he does not think it would be that expensive but someone will have to get with them an get costing. i can get you their contact info if anyone wants it.

Why not replicate some of the various all-metal ones out there and ditch the whole concept of some kind of grip treatment (foam, rubber, silicone, whatever)?
Then sourcing an extra part becomes a non-issue.

The rubber/foam is just so... Cheap.

Could some nicely milled aluminum sleeves take the place of the rubber? If its technically possible it might be able to look nice.

Exalt lets companies re-brand their items. Put AGD on a exalt grip, slide it over the foregrip and call it a day already.
