Hello
        In turning Acrylic pens beside wet sanding
        what grit do you start with?320?And also
        do you usually paint the inside of the blank?
                                                    Thanks Anthony

The grit you start at depends on how clean your tool cuts are. If you've left almost tool marks, you can start at 320.

I paint both the tubes and the inside of the blank. If you do that, or even if you only paint inside the tubes, remember to drill a bit bigger, or you will simply remove the paint when you insert the tube.

+1 on how clean the tool cuts are. I generally use a negative rake scraper to do the final passes. Even so, there are very small marks that need sanding. I start by wet sanding with this Norton sponge-backed wet/dry sanding pad Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register (cut into smaller pieces) to start, then move right into micromesh through all the grits, and finish with PlastX.

Regarding the painting, this will depend on whether your acrylic is opaque or translucent. I tend to do mostly opaque or near-opaque, so don't paint - however, I have heard that you need to ensure your adhesive won't damage the paint when gluing the tube in the blank.

Personally, I use a HSS skew. Material removal may not be as rapid, but I can usually begin wet sanding with 600 wet/dry sandpaper.

+1. I can control the cut of the HSS roughing gouge and skew better, less chance of me shredding the acrylic into crystalline chunks.

The Hunter tools work well on acrylic.

I've not yet turned any acrylic pen blanks, but if you can get used to a skew and make sure to keep it sharp, you can get a surface which just about doesn't need any sanding.
