How much is too much?
I searched but the threads don't answer my problem.
It's a 7a but I suspect this is an issue with other models.
I spent all day trying to get the weldment to rotate smoothly in the bearing blocks.
The weldment rotates but not bearing smooth. It's takes a little force to move it.
The weldment was not round and the blocks were too close in tolerance.
A little squeezing got the weldment reasonably round within a couple thousandths.
A little sanding got the blocks to rotate without binding.
It's not the center block. In or out, it's about the same. I do have washers between the center blocks. One on each bolt.
The outboard blocks are the black predrilled type. They are not split and the hole does not go all the way through.
I got the blocks to rotate freely on the ends of the weldment but the weldment gets tighter when the block bolts are torqued. AN3 bolts torqued to 20 inch/pounds. The bolt holes were drilled on a press and perfectly square through the blocks.
I don't want to go too far and end up with the weldment breaking in sloppy.
Any advise is appreciated.
