CA finish peeling at pen kit band-any suggestions?

[Nickfff]

Hello,
I have been doing CA finishes and usually they come out very nice. Lately, I have noticed some ca finish peeling near the band...

Any suggestions on something I may be doing wrong to cause this?

Any suggestions on fixing this w/o taking the pen apart and putting back on lathe, sanding and refinishing?

Thanks in advance,
Nick

Take a look at how you are pressing your finished pens together. sometimes if you are pressing the nib into a blank you can put too much pressure on the other end and chip the finish. Don't have a good solution for that problem though, just figured it out myself. I'm sure somebody will have one for us though.

There is a tendency for this to happen when:
1. using very oily wood without wiping it with some cleaner such as acetone or alcohol.
2. pushing the fittings on too tightly jamming them - will cause the CA to pop up from the wood; this happened to me a couple of times on oily wood.
3. a small amount of glue is inside the tube and pressing the parts in expands the metal a very very small amount causing the tube to expand.

I've also had this happened when I end-milled the pen after finish "smooth" but not down to the brass tube again. This can also happen if you have mis-sharpened your mill so it isn't milling at 90-degrees to the tube leaving the finish higher than the tube. Both cases makes the wood/finish higher than the brass so when you press the parts together you press on the finish before you've pressed the band all the way on and "pop" goes your finish. Either right now or after the wood expands on a moist day.
