Topic tags/keywords: question

I just completed a tall segmented vase and i used blo friction finish on the project. since i constructed it in layers i could finish the inside fairly easy, but when i got to the neck it was hard since the inside diameter was only 1 inch.
and was concerned about my finger getting twisted off, This is my second vase and so far i always used the same finishing material. Since you dont see the inside like in a standard bowl could i finish it inside with say shellac rather than the same as the outside. does it matter would the wood shrink or expand differently it would be a lot easier to just brush on several coats of sealer inside any comments?

I think that would be fine. And even a mismatched surface will be better than unfinished in terms of shrinking/swelling.

The shellac will be fine. If you are using a commercial or self mixed friction finish, they usually have both shellac and BLO in them so it would not hurt to get a little BLO on it and then top it with a 1/2 lb cut shellac.

You just go ahead and use the friction finish. It doesn’t really matter if it gets fully buffed, though I would probably try wrapping a cloth around a dowel or something and see if I could buff it a little bit at least.

I would probably finish it with the same friction finish, just slow down the lathe to make it safe. Maybe ,even with the lathe turned off, it just won’t shine like the outside.

Woodturners are the only people that will look inside.

I hope you are using paper towels or tissue, and not a rag.

With a 1” opening all you need to do is seal the inside. No need to friction polish it. All of my segmented work and one piece hollow forms (see my LJ projects) are fully assembled and hollowed, then finished. I just pour in shellac, oil, etc slosh it around, cover all areas, dump out any liquid left.

Thanks for all the suggestions i tried using a round dowel but using a small cloth didnt work Hairy i think just applying the non spinning would work, i made the utube video guy called it shine juice I made it with blo alch and shellac works pretty good but i though you needed heat to cure it thats why i did not just apply it. OSU55 i like your suggestion just pour some in do you give it several coats?

For inside, Don’t put any blo in the mix. Just shellac, thin with dna if needed. Shellac can cause the wood to swell, possibly cracking the piece, though segmented work should be ok. 2# cut doesnt penetrate as deep as a lighter coat, so doesnt swell as much. Get a coat for coverage, let it sit a day, then do another if you want it fully sealed, but it isnt necessary. Thinned poly doesnt cause as much swelling. I finish more pieces with poly and seal with it.
