Green Woodturning, Free Walnut
Could someone assist my googling? g Two days ago the power company
converted a walnut tree in our backyard to a pile of branches and a stack of 14" logs about a foot to a foot and a half long. I painted the ends of the largest of the logs before running out of old paint. Then I unpacked my new Harbor Freight (I know, I know) mini lathe and set of starter lathe chisels and made three practice "Christmas Tree Ornaments" from lengths of the branches. No finish was applied. This morning the two that are under an inch in diameter are ok but the 2" diameter ornament is badly cracked. How does one successfully work with green wood? Strip off the bark and let it sit a year? In any case I'm not going to be able to turn all the wood so there are some free-for-the-hauling walnut logs in Bowie, Maryland USA if anyone wants some wood. Do the obvious to the email address. -- Mark |

My best luck has been using several methods.
1) Remove the pith out no matter what you do. 2) Cut and turn as much as possible green. Leave it thicker so that you can turn away what warps. Usually bowls in my case. Then anchorseal it and let it dry. I just build up my stock often up to a year then. Then return to the lathe turn it again then put on your finnish. 3) Cut and turn as soon as possible but leave it thin so that it can warp without cracking (again usually bowls in my case). 4) Cut into spindle stock. (Leave pith out again). Then seal the ends, I use anchorseal or parafin on the ends. Anchorseal is safer, but I found a temperature controlled pot to use for parafin and seal ends outside. As long as you stack them with stickers in between I have had very good results creating my own spindle stock. Again I usually set this aside for later use after it drys. A very good book I would recommend is "Turning Green Wood" by Michael Odonnell though there are now many good books and videos on turning green wood. Also website searches on turning green wood will give you many ideas. Have fun and good luck. Remember even if you loose some it was all free. After I few times of experimenting you will find what works for you. "Mark Jerde" wrote in message ...

Green wood is a fun thing - like others have said, coat.
Don't plan on a pith line in anything - it will be a hole. I have turned green wood and taken the 1/4" over size walls to a drying area to dry slowly. I have also taken an almost finished green bowl and put it in a microwave. afterwards you can shape a hot bowl - at 50% defrost or the like. shape the bowl into unique non-round shapes. Hand sanding is required. The precut bowls/cups - are drying faster and need to be slowed with damp rags. When the rags dry and the bowls dry - (depends on the location!!) then remount it on the lathe and complete the bowl or cup..... Richard Raffan "Turning Wood" - video tape workshop is interesting as it is all wet cutting. It might help if you search for it - ISBN 0918804566 He has a companion book as well. Martin |

Hello Mark,
Strip off the bark. Using a chain saw or maul, split the 14" logs down the middle. This is to remove the pith. You could also rip the logs into small flat pieces 2-3" in thickness. Coat the ends with wax or loads of old paint. Keep outside, covered (out of the rain), and off the ground. Air must be allowed to circulate. Figure about 1 year per inch thickness but I personally can't wait that long. Use the branches to practice and develop your skills with the skew and gouge.

My particular informant prefers using plastic film wrap (saran or equivalent), wrapping the piece(s) well, & storing away for about a year. Either way, it will be a long time until you can turn the green wood into a useful thing without cracks - either cure the stock, or cure the turning... HTH |

I too like Wax, it has worked for everything I have sealed. The only wood I had problems with was the ones I used a commercial sealer ! One way to melt the wax is to use an electric deep-fat fryer, they will handle decent size pieces depending on shape, just remember to turn it off when the wax is molten, its normal temperature is a little high. If you plan on sealing a lot of wood, and I mean a lot you can buy wax pellets in bulk at very reasonable prices. Besides if you get bored turning candlesticks, you can make your own candles Another trick is to add colouring to the was to colour code your wood. I usually dip the wood for a few seconds for any moisture to fizz away, which seems to give a better adherence to the wood -- John |

Mark,
Actually, green bowl turning is a lot of fun. Give it a try. Take the green piece (without any pith in it) and turn the rough shape. Make the wood as uniform a thickness as you can, but leave lots of wood in place for the final turning. For drying, if the wood feels really wet (you'll know) I put it in a brown paper bag so it dries slowly for a couple of weeks. Plastic bags don't do it. Otherwise I just put it on the shelf. I weigh it first (a cooking scale from the Mart on the Wall). I weigh if each week, and when I get the same weight for two weeks, its ready to turn. Usually about a months time in MN. I don't slather it with anything, unless I have a big (12" plus) bowl, or I know that the wood is fragile. Then, I just do the end grain portions of the outside, but not the inside. After all I do want the moisture to LEAVE the piece, not be trapped in there forever. I use Anchoseal, shellac, old latex paint, whatever I have. After all it will be turned off when I finish the work. Mounting the wood is the most seriious problem. Remember that the bowl has changed in all directions when you put it back on the lathe. If you use a glue block on your faceplate, it may have warped enough to weaken/break the glue joint. You may have to reflatten the bottom and reglue. If you use a scroll chuck, you will have to redo the tenon or the recess, as it won't be exactly round, and wont hold the wood securely. If you just screwed the wood to the face plate, you should be fine Once it is securely mounted, get out your chisels and create beauty.

You might notice that most replies that you got addressed bowls, the most common thing turned green.. I've never had luck with anything green that was spindle turned, maybe others have.. Anyway, after trying to dry rough turned pieces, using about every method known to man, I quit rough turning.. I turn green wood to final thickness, or maybe I should say thinness, and if it will cooperate, I sand and apply an oil finish.. They very seldom crack, but they warp like hell.. which is something that I happen to like and also seems to sell well.. Someone looks at a "banana split" dish and asked how the hell I carved it..

Cut or split the branches to remove the pith and then use the microwave (watch out for SO (-: ) Use it on about 75%power and zap for 30 seconds then allow to cool and weigh. Repeat ad nauseum until the weight is stabilized and you are ready to go. |

Hi Mark,
One lazy man's method of making stable spindle stock is by relieving the internal stresses of green wood by just letting an untreated log or limb, say about 18" long, crack & split by itself. Not for all species, but often there is one deep longitudinal split (sometimes two) all the way to the pith that "releases" much of the internal stresses and strains. Then just debark and rive along the big split and cut up the two unequal halves into spindle stock sizes of your choice. I sometimes slosh liquid dishwashing detergent (or whatever it's called in the UK) on the two halves before cutting them up, but that's another topic to discuss pro & con ad infinitum (and nauseum) along with alcohol soaks, microwaves, paper sacks, incantations, acts of congress (or parliment), etc. etc. Turn to Safety, Arch Fortiter http://community.webtv.net/almcc/MacsMusings |
