Hi Group, I just finished rough turning a pine bowl blank that's
very green up until now I've mostly worked with dry wood. The
blank is very wet, we're talking water and pitch, down South
they would probably call it grease wood. I've heard of various
of drying, brown paper sack, add sawdust and microwave oven.
I'm new to drying so any help would be appreciated such as to
the best method, storage and such. It's winter here right now
and we're having high 30's during the day and 20's at night
right now. I'm doing practice turnings on my new to me Jet
1236. I've been away from turning awhile. Thanks, Jim
nobody has said this so i will - put it outside so it freezes
hard - that will rupture the cell walls (with ice crystals) and
reduce the potential for distortion and cracking. to speed up
the "processing" you could bring it in for a day, then put it
outside for a day - repeat several times.
I tend to turn wet wood to final (thin) dimensions in one shot and
never come back to it, just sand and finish - you didn't say how
thick you left the walls - I often aim for 1/16th or so on
"active" wood like eucalyptus, and 1/8 to 3/16 on more stable
woods
I left the walls at about 5/8" to 3/4" and the bottom about 1 1/2"
thick. The height is about 8" to 9" and it's about 9" across. It is
getting down to 10* to 20* at night here so freezing might be an
option. I could also put it in the chest freezer. My next move is to
buy a new roughing gouge as my old one had grab and broke at the
tang just when I had gotten it sharpened to where it was working
good. I welded it back together but I won't trust it now and I was
a welder forever and have a Heli-arc and know what I'm doing. I'll
use it for light duty stuff. I'm not sure what brand it was maybe a
Disson. I've had them since Jr. High and that was a long time ago.
A question on roughing gouges can a spindle roughing gouge be used
for bowls or should one get one of each? Jim
1. never ever ever EVER ever !!!! use a spindle roughing gouge on a
bowl - in fact, you might be well served by putting it in a different
room when working on bowls - never use a regular bowl gouge either
2. you left the walls and bottom very thick by my standards but maybe
what we are aiming for is different (there is a gallery of some of my
stuff at www.wbnoble.com - click hobbies/wood turning and find the
gallery link) - I like reasonably thin walls (usually, unless the
shape wants thick), I like distortion and discoloration, and so on.
So I turn to final dimensions and sand it right away. Rarely does
this fail me - for some woods, boiling or freezing reduces distortion
and cracking - if you do that, then you need to resand afterwords
I'm planning on doing the finish turning after it dries. I'm most
playing with it right now. I was looking a set of Savannah tools off of
Amazon to replace my old tools and visiting my local Woodcraft store,
the second eivl store next to Cabela's here locally, and look at bowl
gouges. On the welded tang I let it air cool but I'm still going to
replace it. Here's the link to the tools on Amazon
