Steve - I had tubes welded in the stanchions for Rhapsody along with other machining work I had done so don't know the allocation of costs just for the tubes. There was $22 of material (stainless tubing) and I anticipate about 2 to 3 hours of labor spent on this for cutting the tubing, welding, grinding and polishing. I used a local machine shop that was recommended to me. You can check the labor rates in your area, but I would expect it to run $55 to $95 per hour for a skilled machinist.
