Hello From Florida!

[SongwriterER]

Thank you all so very much. After making certain via centerline and measurements, the predrilled holes seem to be spot on.
Interesting enough however something extraordinary has occurred.

After cutting some pieces of the "skin thin" mahogany I have, wetting it down and forming it around some hardwood dowels, letting most of the moisture dry-out and then inserting the wrapped dowel into the predrilled holes to see if this might work. An hour or so later, I began to removed all the dowel wrapped pieces and found that the remaining moisture has caused the pre-drilled holes to shrink. Now the original hardware is so snug that they'd need to be forced in which I won't do. I'm quite certain that as whatever moisture exists around the pre-drilled holes at this time, the holes will become larger again. If so, I plan on proceeding with the plan to use the mahogany liners and then pressing in the posts at the proper time of assembly.

My sincere thanks and gratitude to all for helping. I'll not doubt reach out again to the wealth of knowledge available on this forum before this project is finished.

That is kinda kooky. How thin is the mahogany you are using? The Maple I had on mine was 0.5mm/0.020" and i thinned it slightly with 80 grit before I bent it. It's in now so its just a matter of cleaning it up, but i should have probably tried to pre-form it as you did first.
live and learn i guess!
