Searching for alternate connections to the small wheel holder pin

[jimmythefly]

I'm searching for alternate connections to the small wheel holder pin, or alternately looking for a wheel that mounts to that pin which ALSO has some sort of legal system connection available. 

To be clear, I am working with the typical small wheel holder pin as shown in the pic in black.

Question 1: Are there other parts or types of parts that will connect onto that pin nicely? I'm sure there must be some minifig accessories or other parts that I haven't tried yet. 

I have fit several different parts to it already: 1x1 round plate with hole, 1x1 round brick with hole, headlight brick, travis brick. Technic half bushing, the axle hole on Technic thin liftarms, the center hole on Technic link treads, thin Technic gears and pulley. 

I have also fit several technic pins which have an OK friction fit and sort-of allow other things to be used as wheels, but because there is no internal goove the fingers of the wheel holder pin don't snap securely and in general I'd like a connection that is more secure.  

Question 2: Are there any wheels that fit on this pin that ALSO have some sort of system connection point? I've tried wagon wheels, small train wheels, etc.  Seems like Lego specifically does not want us to use anything more than their intended wheels with these -or did I miss something? The closest I have come is trying to fit the 2x2 dome lip inside the 14mm wheel (pics below). It just doesn't fit even with a fair amount of force. 

Thanks.

The only valid connections are anything connecting to the bar (droid arms for instance). Everything else is a hack and what qualifies as an "illegal" technique quite likely. Perhaps it might be more useful to explain what you are actually trying to achieve, so alternate techniques using different pieces can be discussed.

Thanks @Mylenium ! That's what I figured -the only legal connections are things that normally connect to a bar and do not keep the ears of the pin compressed.

What I'm trying to do is use the new vehicle base with suspension and the associated tilting axle with pins in a MOC.

I'd like to use a wheel rim not normally associated with that small pin type of connection, so I either 1) want to connect a second wheel or dish or disc onto a compatible wheel, or to 2) build perhaps a small armature onto which I could attach a single wheel or perhaps a pair of wheels at each end of a short liftarm (like on the back pair of wheels of the Creator space Rover Explorer 31107)

If none of the legal wheels have any other connection points on them, it's looking like I need to go with choice #2, which isn't bad it just will use more parts and take up more space and alter my design a bit.

You might be able to use thinner wheels, like https://www.bricklink.com/v2/catalog/catalogitem.page?P=4624&name=Wheel 8mm D. x 6mm&category=[Wheel]#T=C, that have the same radius as these tires: https://www.bricklink.com/v2/catalog/catalogitem.page?P=30028&idColor=11#T=C&C=11

The extra room you have in the tires, since you use thinner wheels, can be used to insert a https://www.bricklink.com/v2/catalog/catalogitem.page?P=4265c&idColor=3#T=C&C=3

After that you have a +-hole you can use to attach more wheels :)

I see. I've not yet used those parts, so I can't advise on that. however, it seems to me that you could do it with some Technic parts easily, just not as elegantly.
