Picking at the bump with a knife revealed it was More than a Glob of the Pebble paint, there was a lump of metal that was also high. A small file cut the problem area back to flush. I think it may be better now but still looks to be not a mill finish between these mating parts.
The cyl assembly also had a sag in the powder coat and this is adding to the issue, I worked this down with a file as well but think I will take it to work and true it in Mill if it still does not look straight after assembly. [ Guests cannot view attachments ]
