I'm working on a wall-rack for my Sticks. I only have one now, but #2, a Railboard has been on order since last January, and will make its way to me eventually, so the rack will accommodate two instruments.

I want it to be able to handle anything I might acquire down the road, and it appears that instrument widths vary from the 3 1/4" of my rosewood 10-string, 3 1/2" for the 10-string Railboard, and 3 3/4" for the Grand Railboard and Grand Sticks.

If I design the rack to handle these three widths, will I have the range covered or am I missing something? Not looking to accommodate an Alto, or NS, just the regular 34/36" 10- and 12-string models.

Thanks.
