Hello all,
I bought some blanks from the bay and now they arrived in wet newspaper. I do not have any DNA on hand. Should I go get the DNA before I rough them?
Never turned green wood before and these will be my first bowls.

Dewey, I'm not sure I can help but is DNA denatured alcohol??
Dewey yes get your DNA and container ready so you can put them in when you get them roughed out. If you don't you probably will have some cracked bowls. I leave mine in for minimum 24 hrs to as long as 4 days for fruit wood and have had great luck with it. Most times my bowls are dry and ready to go back on the lathe in 3 weeks or so.

Dewey, rough turn the blanks the shape that you want..leave them a little thicker than you intend them to be when finished..soak them in DNA, put them in a brown bag for about a month or so, rechuck and finish turning then put on your favorite finish...BTW your suprise should be there monday

Dewey, you can buy DNA at wallmart, BORG, any paint store....brown bag helps piece from cracking/checking

Dewey,
You don't have to use DNA on bowls, there are other options.
here are a few-
1.Rough turn and then place a paper bag and place on a rack that allows air circulation.
2. Boil the roughed bowl (I think for an hour?) and then allow to dry
3. Rough turn and then re-coat with your end grain sealer and allow to dry for a couple of months
4.Some folks use dish soap solution and then allow to dry
5. rough turn and pack in a breathable container with some of the wood chips from the bowl and allow to dry
6. If your as impatient as I was on my first bowls-Finish turn thin,sand, and apply finish (much of the drying will occur as you are turning and sanding) If your wall thickness is close, it will dry fairly consistently although it may warp/distort to some extent.
Personally I now rough turn and reseal with anchor seal until dry (about 3-6 months depending on conditions) and get very good results. The other options have been covered in other posts with a lot more detail than I can remember. I did try DNA, but it was stinking up the shop, expensive, and gave me about the same results as the Anchor Seal.
Good luck and happy turning,
Tom
Congrats on getting your first bowl blanks - you will love this part of turning!
Check out this site for info on the DNA process: http://www.woodcentral.com/cgi-bin/r...cles_473.shtml
After rough turning the bowl so that the thickness is 10% of the diameter - I soak it in the DNA. Once the bowl is taken out of the DNA - allow it to surface dry a little before wrapping with brown paper bag. You use brown paper bag to slow down the drying of the exterior as compared to the interior. Wrap the bowl as shown on the web site. Write type of wood and date wrapped on the outside so you know what you have.
Good luck with it! Looking forward to seeing the bowls!

Steve has a great link to the DNA method. I use several layers of newspaper and masking tape the rims. I have been making some small boxes from green wood and soak them in DNA in large ziploc baggies, after rough turning. Seems to work well. I have not had a box crack yet. I do wait a couple of weeks on the small stuff as well before finish turning.
All the best.

Dewey, I think the only green wood worth messing with is what you can find locally for free. Buying green wood off the bay and have had it crack when it it hit our dry air taught me it wasn't worth the effort. Green wood can cost more to ship also. There is enough dry wood on the bay if you want to do that.
From time to time you can pick up some short stuff worth turning for little $ at the lumber yard on Stone in the Springs
I would have to disagree with the not getting wood off e-bay. Some wood may not grow where you live. For example, walnut, elm, maple and cherry are hard to find in Hawaii. But we get weed trees like monkey pod, pheasant wood and mango. Also some "exotics" as you mainland folks would consider, koa and other native trees. e-bay has some great deals, and as long as you're careful, and get a reputable source that completely seals green wood in wax, you should be fine. Yeah, if you buy wood from joe blow, you could get screwed.
Just be smart and watch what you buy. Take advantage of the flat rate boxes. You'd be amazed at what can fit in it.
Wood is wood. You could get a perfectly good chunk of kiln dried wood from the store or lumber yard and it can crack and warp in your garage. Or have a giant rot section.
dewey, is your blanks waxed ?????
