I made one from home depot, worked like a charm
2 2" endcaps and some beefy ass allthread\bolts.
I drilled and airhammed the bushing out, so no press needed there...
Nice manufacturing there, I wish I had access to equipment to make stuff like this, A NICE tool like that sure does make things more helpful, ghetto tools work but usually end up tearing up things a little bit\being dangerous to limbs\face and are almost always a pain in the ass... But they usually involve a drill and a power saw so its sometimes fun >: )
Now if you could invent a tool to make rear wheel bearings easy and cheap.... That'd be sweet!
