How do you experts go about sanding the inside of hollow forms. I just created one about 7 inches in diameter by 5 inches deep with a 2 inch opening. Sanding the outside is easy. How do I go about cleaning up the inside?
One thing that I have done - but not "invented" is to wrap a strip of sandpaper around a small wad of steel woo, grab it with a hemostat and sand while the piece spins. Just grip the hemostat-don't put fingers in the holes in the handle. Craft Supplies at one time sold hemostats, don't have a recent catalog handy to see if they still do.
IIRC, this trick is attributed to the late Ray Allen

I took a ball shaped wooden door knob attached it to the end of a short dowel and then attached some sticky backed velcro hook strip and the was able to use hook and loop sand paper. I cut small triangles from a disk snader disk.
I used it for the inside of a hollow form that is about 7" deep and only
3-4" dia with a 2" opening.It worked well for me.
A round, bent stick with some hard foam glued to the end. Adhesive spray the sandpaper to it. If you want to get fancy and make it usable to different forms, cut yourself a joint near the end of the stick, hold it together with recessed bolt/nuts and position it the way you want it. Make it as long and thin as you want.
They sell these things in the woodturning/woodworking catalogs too but they're usually made from steel or aluminum and use their power sanding foam disks that they sell separately on the ends.
Another way to do it is to just use a flexible shaft on your hand drill and use it with the lathe not running. Can't get up under the undercut shoulders, etc. though.
OR, you could just do what far too many (IMHO of course) woodturners do and stick a too-thin-to-see-or-reach-in neck on top of it and don't bother sanding or even smoothing it well.

The trick is not to have such a large opening that people can stick their fingers in as well as see into the hollow form. Then you won't have to worry about sanding the inside! *1/2 a G*

I simply don't. I generally turn a contrasting colored wood collar with an opening too small to poke your finger in. That way the inside is instantly smooth as glass .

And only sand the places that folks can reach...or see. Regards Dave Mundt
