This is not adequate but this is what I have. I don’t do anything like cad or fusion etc.
I’m still not sure what to do about the oring or sealing method.
I did notice there is a groove in the spindle. I can make it work but I can’t visualize it until I cut the bore fir the bushings.
Then I can put it together, figure out my next move before I machine the brass.
I will have a method to add lubrication and it will be shielded from grit.
One step at a time.
The bushing will be .625 wide and .200” thick. I am going to allow .001” clearance between the spindle and the bushings. As it is now there is probably.005”. Way too much!
I do have the bore coplanar with the base and both ends standing on the surface plate are within .001”. In other words, I’ve been careful with each step. I’m really trying to not screw it up.
