From where are the riblets available, or does one make their own?

The object (as I understand it) is to increase the stiffness of the board and the riblet is what accomplishes that. The riblet is constructed so that the ends connect with the sounding board first and only after the screw is tight does the middle make contact. I can’t see that wedging up the board would add anything to the process nor do I think lowering the tension is necessary. dave David M.

To be sure I was going to be screwing the anchor screw into the bridge I drilled a very small pilot hole down through the bridge. I put both holes spaced between two ribs and drilled so the screws would go between unisons and would not interest bridge pins. Then from underneath I scrapped the lacquer off the sounding board where the riblets would be glued to it. I then applied glue and screwed them on. David M.
