Depending on the wood, reapplication can be just fine. With some woods/styles you con get a noticeable difference that looks “splotchy”. In my experience this is especially true if you wet sand or clean with denatured alcohol, and the wood is figured, oily, or lighter in color.

For what it’s worth, I would put a few more coats on it and live with the results... I’m not as picky as Tony ;)

Tell us more about your application process. How many coats of what thickness CA. What did you sand the CA with before micromesh.

Thanks for the help all! I tried applying more ca before I sanded it bare and out came out pretty well. There is a little discoloration that can be seen on the bottom of the blank in the second picture. Not happy about it but I can live with it for the learning experience. You all were fast and a ton of help!Attachment 17215720180128_165416.jpg

20-30 seconds with each grit? Seems to be way more than you need. Go for 10-15. And a light touch.

Coating with CA using paper towel ends up with probably 1/500 of an inch to 1/250th of an inch of thickness. 3 or 4 coats of CA with paper towel will amount to 1/100th of an inch thick and sanding through is quick and easy. Paper towel (PT) is the applicator of choice but it absorbs 10 to 1 the amount of CA vs what goes on the blank.

If you need to build up, use medium or thick. It might take a 2 to 5 minutes to cure in cool weather but the build up of CA is worth it to prevent sand through. Or add 5 to 10 coats of thin, which is about the same amount of time.

Those pouches that parts come in - put one on an index finger and use that to apply the CA. Gives a quick and smooth build up with 95 to 100% of the CA on the blank.

That little decoration you mentioned - that happens on some woods more than on others, and it bothers me when I happens to me. As TonyL wrote, in cases like that, I sand it all off, or even turn it all off with very light touches and start over.

That is a "feature" you won't find on most of my competitors lower quality pens. $5 more for that pen!
When you hand sand a flat project between finishes you just barely go over it. The lathe is going at several hundred RPM. A very light touch and short action will still get the job done.

Bit of a noob question here. How do you keep the CA from gluing the blank to the bushings?
