Having some trouble lately when I finish the pen and remove the bushings, the ca finish chips off the end of the wood. Should I be waxing the bushings or something else?
Thanks.

You can try waxing the turning bushings or pick up a set of the non-stick bushings like these: https://www.exoticblanks.com/Bushings-for-CA-Glue-Finishing-Set-of-4.html or turn your own if you have access to some UHMW plastic.

About every third pen I wax the mandrel and bushings! CA can get between the mandrel shaft and tube and makes it moderately difficult to remove the barrel from the mandrel. DAMHIKT!
Jacks suggestion is a good one too! I use these and they work well, can be used for any size tube. If you take this route, be sure to touch up the barrel end with a piece of sandpaper. The CA sometimes develops a ridge on the end of the blank and creates leaves a gap between the fitting and barrel.

Chuck the blank between centers w/o bushings and finish it that way. A little acetone when you're done takes the excess CA off the centers. You'll likely have to true the ends, but I think that's a good thing as the CA seals them for sanding. Just how I like to do it.

For those who want to go the UHMW plastic route you can get either the UHMW or HDPE from Grainger for a reasonable fee. I recently bought a 12X12X1 1/2 inch slab of HDPE for $32.00 and was able to pick it up at a store near my house thus saving the cost of shipping.
You can also get Delrin (Acetal) rods from online metals. 1" Diameter rods are about $5/ft. It also helps when sanding light woods keeping metal bits out of the pores and reduces wear on the bushings.

Grainger also sells rods for just a few bucks.

Another solution is to periodically soak the bushings in acetone to remove the CA.

That's exactly how I do it. I keep a little acetone in a small jar so I can put the live and dead centers, tips only, into the acetone and let it soak a bit.
