I do know that oily woods such as rosewood and teak need to have the surfaces cleaned with a solvent in order to remove the natural oils in the first few cell layers so a finish will adhere.

When removing the oil you have to begin the finish process soon as waiting will allow the natural oil deeper in the cell layers to gravitate and replace the missing oil.

Your sequence sounds reasonable. If you’re going to cover a surface with felt, I think it would be a waste of time to finish it beyond 60 or 80 grit. All you need is a flat surface and the “tooth” from a rougher paper will help the adhesive stick.

I typically do about 3 coats of shellac, rub it smooth with greeenie to remove any dust nibs, and add a coat of paste wax.

If I am sanding a sequence of 80 > 150 > 240 > 320

Would I pyrograph, sand 80, shellac spray, wait 45-60m, sand 150, spray and wait, sand 240, spray and wait, sand 320? I thought the shellac acted a sealer as well so no wax is neccescary? Or is the shine from the shellac not good enough? What would be my options after the 320 grit sanding?

Spray can will work but simple liquid shellac will work much better. With spray can you need to apply very many layers, which is a pain with round objects like pens. Most of your shellac will end up in the air around you.
With a can of liquid shellac you can simply immerse the pen into the can several times to get consistent coats. Or you can wipe it on with a rag.
