You could drill a hole in your axle and use a roll pin and the hubs lynxguy suggested.
A couple of the things I found are actually clamps and have set screws to hold them on an axle. Something like this should not need any holes drilled and might be able to fit the shaft of a GHM-04 or other GH motor. This is why I found the clamps to be interesting.

Personally I would really perfer some high strength aluminum rims with foam insert wheels and hex hubs. That would be nice for the more bigger bots that people so often love to make.
I agree. I don’t really like using adapters, but do when necessary. I would much rather just have a new hub to attach to the GHM shaft which would mate with the hex hubs of the R/C style wheels.
I’ll build a multi-wheeled rover just so I can use some of the cool blue chrome wheels. 
I want to build (and have a partial design for) an SES six wheeled rover chassis with independent suspension. I just need an SES compatible bracket so I can use R/C trucj shocks for the suspension. 
Yes, somehow, this HexRover will have blue chrome wheels.

WOW, you always amaze me! 
I’d love independant suspension for some of my rovers but havent had an idea of doing this. Seems fairly complicated with springs and shocks and whatnots. 
Well, I think if I ever stop amazing you, I should probably hang up my roboteer hat.
Actually, to me it seems pretty easy. It’s a matter of getting the brackets necessary to use stock components and putting it all together. I already have an idea for the bracket I will need. You will be able to see the design for HexRover soon.

Great!
Look to the R/C world for help here. Pretty much everything in the R/C hobbyist realm is designed in a modular fashion, to facilitate being able to repair just the part or assembly that breaks, often without having to disassemble too much unrelated stuff to get to it. The racing cars and trucks are particularly good about this, since the manufacturers understand that you only have limited time in the pit between races, and you often need to make repairs as quickly as possible, in order to be out there on the track again in the next heat.
Get some “hands on time” with a few of the R/C trucks out there, and you’ll find that a lot of them have suspensions, transmissions, and drive trains that come off in whole chunks, and are quite adaptable to robotic applications.
David P Anderson (“DPA”), of SMU and the Dallas Personal Robotics Group, has made a number of extremely nice robots, with exceptional capabilities. Of particular note to this conversation is his jBot robot. [ link ]](http://www.geology.smu.edu/~dpa-www/robo/jbot/index.html) Its chassis is based on the suspension and drivelines of one and a half Emaxx R/C trucks.
The Emaxx has some nice features to it - It’s four-wheel drive, the front and rear suspensions are symmetrical (ease of adaptation, and you only need one set of spare parts), the power transmission is easy to get to and very adaptable, it’s a rugged platform, and perhaps most importantly, the entire “maxx” series is extremely popular, so replacement and hop-up parts are very easy to come by at any hobby shop. I’ve seen quite a few of these trucks converted to Robo-Magellan contenders and teleoperated rovers.
About the only real drawback I’ve been able to identify with the Emaxx chassis is that it’s apparently only sold in a “ready-to-run” configuration, in a combo pack that includes a 3-channel radio (throttle, steering, and shift the gearbox between low and high speeds). I’d much prefer to just get one without the extra expense and throw-away electronics of the radio gear and speed control - preferably in bags of parts that you put together yourself (I believe that you learn far more about how something works by putting it together from a kit than any other way).

…and smart, too; watch some of the videos. I particularly like the one where it’s navigating around the building that’s in between the start and end points, determines that it’s gotten itself into a dead-end corridor, switches behaviors until it determines that it’s out of the dead-end, and then resumes its original navigation task.
DPA does really nice work.
Journey Robot is one of my all time favorite robots, and really is some superb work both in hardware and software. In fact, that’s where I got the inspiration to design my HexRover, which will be SES compatible.
We are veering quite a ways off topic here though. I just want a way to use all the cool R/C truck and buggy tires, especially the blue chrome ones, on an SES compatible rover, like, um, HexRover for instance.

Oh, that’s easy, then.
The HUB-05 adapters were designed to work with pinned shaft R/C vehicle outdrives, which were very common for a long time (most of my old racing spares will mate perfectly with them). We just need a new hub design that mates with the 12mm hex drive that has become the “standard” fare for R/C outdrives.
We all just need to shout it out all together on the count of three:
One…Two…Three!
[size=150]“Jim! We need a set of twelve millimeter hex-drive hubs!”[/size]
…and now we wait patiently while he works some up. when they appear in the “What’s New” section of the site, we all order them, and everyone goes home happy.
[size=59]That’s why I said “wait patiently”.[/size]
[size=59]Why are we whispering?[/size]
[size=59]IDK…is this small enough for you?[/size]
Yeah, back in post #4, and all down the first page of this thread, it sounded like he was working on a solution, which is why I didn’t worry about kidding around about it up there. It sounds like this is something that’s already in the process, so it isn’t like we’re dumping anything more on him than he’s already got.
Just the fact that he’s got these forums, and spends as much time as he does in here, seeing what we think of his ideas, and asking for input, makes Lynxmotion one of the most responsive companies in the market, when it comes to addressing the needs of the customers. I’m sure we’ll be seeing hex hubs in the lineup, just as soon as a source can be secured for the rims he’s looking for, so the hubs can be designed that will work reliably with them.
I think I understand the problem - designing a product to work with someone else’s product, the specs of which can change at any time, without your knowledge. Even though the drive may still be a 12mm hexagon, there’s no guarantee that the inner diameter will remain the same, or the shape of the webs will still allow clearance for a flatted portion of the hub of a given size from one batch to the next.
Yes, these things take time to pass through the development process. that’s where “waiting patiently” comes in.
Exactly. Just the fact that Jim is actively looking for new wheels that happen to have the hex hub is what gave it away for me.
I could not agree more. Well said!
Very true. I am sure I will eventually run into this same thing, because I want to make some brackets that will allow attachment of a pair of R/C truck shocks to SES parts. Unless one is willing to purchase a HUGE inventory of the part you are fitting a bracket for, you just can’t tell when things might stop fitting together. With the R/C stuff, I don’t think companies are generally going to do that unless they find a much better way of doing something and other companies agree and follow suit.
Agreed. Oh, I get anxious for something when I am ready to use it and it is not there, but that’s just me. If it’s possible for me to create what I need, then I might go ahead and do that though, especially if I see others need something similar as long as it won’t step on toes (like Jim’s). Maybe we will have a good solid hex hub for the GH motors by the time I am ready to use those cool blue chrome wheels…

You could try to make your own hubs while you are waiting! 
That would only happen if Jim were not already in the process of making such a hub and I was ready to use the wheels I want. I am no where near even starting construction of HexRover, so I have lots of stuff to do right now. I have to finish The BiPod and complete the coversion to motors for WALTER before I can start another project.
