Ray, I have a Cycle Hiil tire changer made by No Mar that came with a similar to the MoJo. The end for mounting the tire is different and I was considering buying for some of the heavier tires, but I found a guy on youtube that made his own and I think I'm going to try to make one like his. The big difference is that he put a bearing on the end to help the tire to roll over the rim. Check it out https://www.youtube.com/watch?v=85-K8Qi4UTA

Hi Bill, can I assume the 5/8" rod fits where the threaded end of the original center post goes in?
Also, can you go into more detail of the bearing. Do you have a photo?
No, since only one of the three plastic rim clamps is fine-adjustable, the wheel bearings will never be centered over the threaded hole where the original center post was intended to fit. (That's what makes the tool unusable as it comes new, apparently after designing it no one ever tried it!) Instead I added the plastic bushing at the top and run the 5/8" rod through that and down into the upper wheel bearing. It does not need to go further down through the hub since the rim clamps are what hold the rim stationary.
I have not added a bearing to my mojo bar, it is just the stock bar with the plain steel end pictured above. I was referring to the bearing in the video link Paul posted. Thought maybe you could locate a bearing on your home made bar to match the location of the plain end on the mojo.
Here's the bushing I made for the top to hold the 5/8" rod. That top arm has plenty of movement in it to be able to line the rod up with the upper wheel bearing.

Don't have it all worked yet, but thought I'd pass along updates.
NoMar ends came in. I believe they're use to mount the tire. I'll be using it for dismounting. Kinda cool. It's got a steel insert for support.
Took a different approach to the center support. Machined a piece of 3/4" rod, with 12mm, 14mm, 17mm steps and left the last end at 3/4". The thought is to insert the end into various size bearings/openings.
Didn't want to machine the end after welding, so did a series of plug welds.
