Hello everyone,
Can someone give me light regarding the DNA process on greed wood? Can I DNA wood blanks or I need to rough turn them first? I experimented and did rough turned what suppossedly planned to be a flower base. Soaked the piece on DNA for three days, wrapped in brown paper for a week but still the wood cracked. The vase was turned into shape but not hollowed. Sorry, I pick-up the log by the roadside and have no idea what type of wood I got. I also tried to turn a smallish "mushroom" using green pine and applied the DNA process as above but to no avail, cracks eventually appeared. What gives?:confused: Thank you very much. Godspeed.

John, the wood does have to be hollowed. I rough mine out to the form I want and then hollow it out leaving it about 3/4 to 7/8 thick. Soak in the alky for 24 hours and then take it out . I just double a couple pieces of new paper and tape it up. Poke a whole in the opening , write the date on it and put it on the rack for no less that 2 weeks. If you leave it to thick it will split most of the time.

John, check out this site for Dave Smith's info on alcohol drying:

Hope this helps you out!

If it is a endgrain piece normally on vases, pencil pots, etc. I just turn them down to the final form. Walls no thicker than 3/8" to 1/4" thick. You will learn there are certain woods that are going to crack no matter what you do. I have never turned box elder that it didn't crack on me. I turned a box elder hollow form Sunday which was endgrain and it was cracking as I turned it. If you do bowls, vases, lidded boxes like Mike said you need to rough turn them and then soak. Bowls I leave the walls 10% of the width across the bowl. If the bowl is 10" across or bigger I leave the walls at least 1" thick and then when dry then turn it to finial size.

Steve gave you a good site that Dave Smith has lots of info on using DNA.

Mike, Steve and Bernie, thanks for your valued guidance. Really appreciate the comments. Mike, really like the artistry in your work. Someday, may I e-mail you privately for tips on "segmented turnings"?.

Godspeed.
