It's all a matter of money.
If you can find old lawn tractors with the differential they have 3/4" axels. But it almost takes two as you need to take them apart and use two long axels. They come with one short and one long axel. They have key ways all ready cut and you can get the hubs out of some lawn tractor wheels to use for hubs. then just weld spoke flanges on then.
