Post subject:  First build rosette question

Installed a Rosewood rosette on a spruce top with titebond. Fits nice almost no gap. All woods are very well seasoned for guitar building. I would prefer no purfling just a little Rosewood dust. Would there be any issues of wood contracting? I like simple wood inlay design. I have some wood purfling coming at 1/64". Appreciate the info since nothing I've read has delved into the practical use of purfling. Image

Be careful with water based glues. Don't install rosette into a channel that is too tight. Even with water base I would still seal the channel and top with shellac prior to installing rosette.

I've been putting in rosettes with water based glues for decades. They're a problem if you make the channel too tight, of course, but I've never had any issues with bleeding or discoloration with them. Sealing the wood would just reduce the strength of the glue joint.

I would seal the channel if I were using CA or epoxy, particularly if any of the woods in the rosette had been dyed. I had some epoxy pull color out of some black dyed stock once that bled for a long way into the end grain.

For larger rosettes I agree tite bond original or elmers white glue when I do the old martin style with the wood purfling I use duco cement. Here tite bond or any water wood glue will make the process very difficult. Duco is also finish friendly

I do remember reading not too tight on the channel. I pushed the rosette in relatively easy, but perhaps some purfling is a good idea. Having fun though, I've been gathering equipment, information and tools for several years. I thought I found my calling with reconditioning and repair, I love builds even more

Duco on all my wood rosettes. No need to seal the channel with shellac, and it is invisible under finish.
Where are you considering the use of purfling? In general, all the rosette channels are routed first, before installing the rosette(s).
You mention rosewood dust, which is not recommended on spruce.

Yes naptha to wipe it clean and seal before finishing or you will probably get rosewood stain on the spruce.
