"How do you keep the CA from gluing the pen to your bushings/mandrel, etc???"
Before applying the CA glue, I give the bushing a coat of "Renaissance Wax". This does not stop the CA glue from plating on top of them. It just stops the glue from adhering to the bushings. What you end up with is a clear shell that comes off easily. However, you may find that when you attempt to separate the bushings from the blanks that the finish cracks right where the bushing meets the blank! And that is truly frustrating.
Here's my technique for getting around all this.
After giving the bushing a light coat of wax, I apply a light coat of Boiled Linseed Oil to the blanks. Then I give the pen several coats of thin CA glue. Then medium, then a couple coats of thick, followed by one coat of thin.
On a suggestion from a fellow pen turner on Penturner.Org, I have been using "finger cots" to spread the glue over the pen. These are those little "finger condoms" that doctors use for,...ahem,...examinations. They allow you to spread the glue evenly and keep the glue off your fingers. After you're done, in the trash they go. You can get them rather economically in bulk from any store that sells medical supplies.
BTW, in case you're wondering why I use BLO.Scott Greaves suggested it to me and I've found it to work just as he had said. It helps to pop the grain and for some reason, makes the CA glue wick into the wood nicely. It also seems to react as a catalyst with the CA glue, which hardens to a nice shell.
After the glue has hardened, and BEFORE sanding, I then clean it off the bushing using a thin parting tool. Due to the prior wax application, it comes off with hardly any effort. With the lathe off, I then score the joint between the bushing and the pen blank with a razor knife. I rotate the spindle by hand and just ride the tip of the razor right into the joint. This helps to insure that the CA glue will not crack anywhere but at this joint.
I then sand from 220 grit, all the way up to 12000 grit (micro mesh). Using this regimen, I've found that the CA Glue polishes up to a mirror finish (IMHO, it almost guarantees a sale).
Before removing the blanks from the mandrel, I buff with White Diamond polishing compound, and then Carnuaba Wax.
I remove the blanks, and sand the ends of the pen blanks flush with a piece of 600 grit sandpaper. The sandpaper is held, grit side up on a nice flat surface (my workbench). I then hold the end of the pen blank flat on the paper and move it around a bit. This helps to remove any excess CA glue that may impede the assembly of the pen.
The assembled pen then gets a light coat of Renaissance Wax to help it resist fingerprints.
I was just about to give up on CA Glue finishes forever when I gave this technique a try. So far, it has worked out very nicely.
See ya around,
