For those turnings with hollow insides where you cannot really see inside very well like a vase, is it necessary to try and add some finish or coating to the inside. I thought of pouring in oil, pouring out the excess and let it dry.

dkulze said:When I do hollow forms, I try to sand any visible inside to a relatively high degree. Since lots of my forms have large open areas and voids, this means sanding to a high finish. Believe me, it's a true pain sometimes and often better done with the lathe off and locked. For anything that is not easilly visible on the inside, I sand any area that can be touched when reaching into the top with a finger and leave the rest as is.

How to sand a weed pot
If you wanted to sand the inside of a hollow form with a small opening go to the beach use a screen to separate some sand into course fine and ultra fine. Fill the hollow form about half full of the course and put a plug in the opening and turn your lathe on at a very low speed. This would work like a rock tumbler, let it run for a couple of days and change to a finer grit and repeat the process. So you will be prepared when someone breaks out their fiber optic light can camera to examine the inside of your vase.
I thought that was the reason for the small opening.I am curiuos though. For those of you who do work for galleries......how do you handle the inside of hollow forms? Do you have a higher standard of finishing for the inside of those narrow opening hollow forms than the rest of us duffers might?

Those posts were from 2006. I doubt that many of them are still with us.Have you had any success with this?
Beach sand has a reputation for being dull from all the tumbling in the ocean.
I never sand inside a hollow form and some have large opening. Just use a scraper to smooth any tool marks from the cutters.
Thanks, didn’t see that an old thread was resurrected.Those posts were from 2006. I doubt that many of them are still with us.
