I've been turning bowls for a while and now want to expand my horizons
into some hollowing. If I am using green wood is the procedure the same
as for bowls - ie rough to 10% of the diameter, let dry then finish?
Or should I just hollow the green wood to finished piece? How do you
experts out there handle this?

Thanks for your opinions..
Debbie



===Well, Debbie, since you opened the door by asking for opinions . .
. ! My suggestion is to use LDD on green wood and then you don't have
to worry about waiting for drying or have to finish it in one go.
Since all the big guns are into visual media production, I have given
some thought into producing "the" definitive LDD VHS tape or a CD.
The problem is how to make a video tape of a chunk of wood sitting in
a soap solution exciting to turners ("turn" them on, you might say)!
Maybe scantily clad models of either sex (buyers choice) sharing a tub
of LDD with the wood? That might give me a toehold in JJ's market
base!*G*

Debbie,

I just finished a hollow turning out of green cherry. Unfortunately, as
it dried, the base DID warp a bit so the piece rocked on the table. The
owner has given it back to me to flatten out the base again. Their
comment was that they didnt want folks to see it rock and think poorly
of the designer. Thanks MOM! LOL

Leif, I have been away from the group for quite a while, but it is nice
to see you are still here pushing LDD. I guess some things never
change. Thank goodness. As to the models in the hot tub with the LDD,
I cant help but picture the scene from 'Back to School' with Rodney
Dangerfield in the tub with the ladies while wearing a mask and snorkel.
I keep picturing bowl blanks floating in there too!

You must make allowances for the bottom warping because it will always
do that.

First, the bottom must not be flat. It needs to be hollowed so that the
piece sits on a thin rim of wood. Then, you need to flatten that rim
after the piece quits moving. Turn the piece thin and let it sit for
several days. Then there are several things you can do with the bottom.

You can glue a piece of sandpaper to a flat surface and sand the bottom
rim flat by rotating and rubbing the piece on the sandpaper. Low tech
but it works just fine.

Or you can reverse chuck it and re-turn the bottom rim. Reversing it
can most easily be done using a vacuum chuck but since you are turning
only a small amount of wood (the narrow rim) you can also just try
taping the piece to some sort of a home made jam chuck.

Better yet, you can also just hold it against a jam chuck with the tail
stock and use a piece of scrap at the tailstock end so that it doesn't
make a hole. BTW, I'd use a small scraper on the rim or use a skew as a
scraper. You aren't taking off much wood and it would be a shame to
screw it up now.

Hope this helps.
