I’ve twice had a machine shop do the best they can to true it up but it is not a permanent fix.
Has anyone else had this problem or have any options or fixes?
Our boat had a fixed plated bronze tube that supports a sliding fixture with a rod that opens the front center window. The sliding fixture has a screw knob that pushes a curved piece of metal against the fixed tube to lock the window in position. When we got the boat, the fixed tube had a lot of dents and flat spots in it from people over-tightening the knob over the years. We replaced it with a piece of 3/4" stainless handrail tubing that we just happened to come across in a West Marine one day. The fixed rod, which I believe is solid, has not given any problems.
We have had no problems with the stainless handrail tubing, but we are careful not to crank down on the locking knob. I'm sure if one did it would dent and flat spot, too, although the walls seem a bit thicker than the walls of the original plated bronze tube.
Don't know if this solution would work for you but it has for us. Prior to us finding the length of 3/4" handrail tubing we were contemplating having a local machine shop simply turn and polish a 3/4" rod for us out of stainless bar stock.
The two photos are the only ones I have on this iPad that show the GB's arrangement.
