Turning Fresh Stock
I'm still in the beginning stages of wood turning but have dabbled with
small items which I've been happy with. I purchased 5 carbide cutters which came with two metal holders, though one cutter is a diamond shape and has it's own designated holder. Therefore, I have one holder for the other 4 cutters. Anyway, I made holders out of square SS stock and now need wooden handles to fit. I trimmed my silver maple tree over the weekend. In doing so, I realized the size of some of the branches would be great for my handles. I shaped one and pleasantly surprised how well it "turned" out (pun intended). The question I have is about the freshness of the wood. It was less than 24 hours after I trimmed the tree, I cut a piece for the handle. Therefore, that puppy was fresh and easy to turn. I've heard about letting wood sit to dry out, then finish. This is the part I haven't any knowledge on. What length of time is required to dry out? Is the main reason to dry for finishes or easier to turn? Though I can't imagine it being for easier turning. That bark and shavings came off like butter. Overall, how do I handle turning fresh stock? Thanks |

Overall, how do I handle turning fresh stock? Thanks Narrow pieces will not take as long to dry out but for regular lumber the general time frame for natural air drying is about 1 year per inch of thickness. You probably will not have to wait that long, given the smaller size and length, but I would let the piece, cut to approximate length, dry for a few to several months "before" turning to final size. They will surely change shape as they dry. Typically green wood is extremely easy to turn but it will change shape and maybe crack or twist. Many bowl turners will turn a green piece to rough shape and then let the piece dry for a year or so before turning to final shape. This speeds up the drying process. |

As a relatively new turner myself, I offer two pieces of advice:
1. Visit the turners' forum at Sawmill Creek. Lots of experienced turners willing to answer fundamental questions. 2. See if there is an AAW chapter in your community. (That's American Association of Woodturners.) Some chapters have mentoring programs aimed at helping beginners navigate what can be a steep learning curve. Good luck, Larry On Tuesday, September 8, 2015 at 3:41:57 PM UTC-5, SBH wrote: I'm still in the beginning stages of wood turning but have dabbled with small items which I've been happy with.

I think I will measure this piece now then measure later to see the difference. The branch was about 2" dia and turned to 1.5" at it's widest point. That was the final measurement...lol. Glad I'm experimenting. I'll do the others larger. Thanks |

Good luck, Larry Thank you and yes, there is a group I met a the local woodworking show last year. Unfortunately, I went to two meets and nobody showed. They meet once a month and after the second no show, I gave up. Perhaps I'll try another time when winter comes. |

Overall, how do I handle turning fresh stock? Thanks It helps to seal the end grain with wax or Anchor-seal (which is a wax-in-water emulsion). This slows the loss of water through the end grain and promotes more even drying throughout the piece, therefore less checking. I turn my bowls thicker than the finished bowl will be. Thickness of 10 percent of the total diameter. Then I put them in a paper bag to dry. The bag makes a micro-climate inside, slowing the drying. After 1 month I start weighing the pieces with a digital gram scale every 2 weeks and write the weight on the piece with a pencil. When the weight loss stops, it is dry for all practical purposes. Different woods dry at different speeds, averaging 3-5 months for a bowl with a wall thickness of 3/4 inch. It will no longer be round, so the finish turning corrects this. Also, avoid using wood with the heart (pith) in it, as it will usually split IME. -- GW Ross Ever wonder what the speed of lightning would be if it didn't zigzag? |

Overall, how do I handle turning fresh stock? Thanks Yes, turning green is really satisfying but I would encourage you to seal the end grain with paint or poly. Otherwise, it may well check or crack because end grains dry far faster that the rest of the piece. Also, I wouldn't use silver maple for handles. It's too soft in my view. Your green wood has a relative moisture content of 100 percent. Stable and thus workable wood is around 12 percent. With dry houses (these days), indoor furniture should be around 8 percent. |

Would alcohol work? It has great affinity for water; if one were to immerse the piece in alcohol for a while and then remove it, would the alcohol have mixed with the wood's water leaving it drier? |

After turning you have exposed a lot of extra wood normally protected by bark. Seal those surfaces and it may not dry at all. BUT I have seen a lot of pieces totally sealed at local suppliers. Hard to tell if they are or were dried properly before being sealed. |

I've also heard the same thing stated, but then I look at what I experience in cutting firewood - admitedly a somewhat different thing. That said, I can cut a tree in August or September, and be burning that tree in December or January - very well. BTW - I'm talking about burning Maple, Beech and Cherry. Green trees show that they are green in the wood stove, by the amount of vapor that they put off while trying to burn. A decently dried piece of hardwood will burn and put off heat. Now think about that - these are pieces of wood that are perhaps in the neighborhood of 4 or 5 inches in diameter (if they were really round pieces), so they should take 4 or 5 years to dry by this age old adage. But - they do not. So - there is perhaps some difference in what makes good burning wood and what makes good lumber, but the difference cannot be that great. If firewood can cure to high quality burning within 2 or 3 or 4 months (while split at much larger sizes), then it just does not make sense to me that dimensional lumber requires these conventional thinking drying times. Yes - I understand the concept of wood movement and the way it is spoken of, but I really have to question just how real that stuff actually is. It has often occured to me that even the best, most properly dried piece of wood is subject to absorbing moisture just by sitting in the garage, so it seems some of this is over exagerated stuff. But - that's not my argument, it's just the things I think about when people talk about all this stuff. Mostly - conversation at this point. -- -Mike- |

When the moisture content of wood is high, you do not get a fire. Try it. You will see a piece of wood that does not get going, and that almost extinguishes itself with its own moisture. I submit that your comment is not accurate at all. Though I may be wrong, your comment is just too generic at this point. So - think about it this way Scott - if wood can go from fresh cut to burnable in the space of 3 months, at dimensions 4 or 5 times that of dimensional lumber, then does it seem logical that a piece of dimensional lumber really requires 1 year per inch to dry? -- -Mike- |

I've put my wet bowls with more diameter to work on inside
and out - rough turned - into a sealed paper sack. Wait a month and put it on the lathe to complete. The paper leaks moisture slowly. Keep out of the sun - don't cook it. I have also microwaved fine finished bowls on very low power then when plasticized I bend or distort the bowl shapes.

You probably will not have to wait that long, given the smaller size and length, but I would let the piece, cut to approximate length, dry for a few to several months "before" turning to final size. They will surely change shape as they dry. Typically green wood is extremely easy to turn but it will change shape and maybe crack or twist. Many bowl turners will turn a green piece to rough shape and then let the piece dry for a year or so before turning to final shape. This speeds up the drying process. Would coating the freshly turned pieces with Anchor Seal or similar help prevent checks as the wood dries? Puckdropper You took my thought right out of my head. I await the answer. |

Water boils at 212F. Wood fibers combust at a much higher temperature. The 212F water must be vaporized and driven off before the remaining wood fibers can begin to combust. If you can create conditions where the wood fiber is at or above combustion temperature and water vapor has not exceeded 212F, you get the conditions where fibers are burning and adjacent fibers are just smoldering. In whatever configuration you have, vaporizing water reduces the efficiency of the combustion process. Lew Lew |

I drove a wood stove for 17 years in the mountains.
We used various woods - some off the property but mostly from the wood man. Every now and then we would get some wood that was a bit green and yes it would boil out the water dry out twist and pop (it was Madrone naturally) and burn. Water logged wood - on the muddy bottom (I use Poly pallets for my wood stacks here, Had a nice Redwood crib I built with my brother there) would take to much to heat to dry out and might cinder. But if one had a good roaring fire green wood burns after a while. You don't want a load of green wood, the fire might never get started. I was near that and used 3 fire starting sticks to heat the unit hot enough to start a fire. Ugly. It was after 2 weeks of constant pouring my path to the wood bin was jelly and my on-porch rick was just consumed. I found some wood on the lower deck that was destined to the wood lathe but got the fire instead.

OTOH, the idea behind drying lumber is to dry it evenly. That means slowing down the process, as you suggest. |

Split firewood is shorter and typically has numerous splits. While the majority of the drying is through the ends, splits can effectively make parts of the firewood thinner in spots. But shorter pieces is the main difference. Lumber is seldom cut shorter than eight feet for drying. It takes much longer for the moisture to reach the ends of the wood than 18-24 inch firewood. |

In the eastern part of the state (and maybe other parts - I don't know), Hickory can be common. Both are great firewood, but I just don't have any of it on my property. I keep about a day's worth of wood in a little craddle beside the stove for the same reason. I tarp over the wood that is stacked outside, and I have 3 months worth stacked on the front porch at the beginning of each heating season (not enclosed, but does have a roof over it). For the most part, it really does not get all that wet once it's stacked. It's surprising though, how little water is actually absorbed into wood from rain or snow, once it's seasoned. I've gone through heating seasons without tarping over my outside wood stacks and to be honest - there's not a lot of difference between the tarped over wood and the stuff that was not. Mostly just the mess that you bring into the house if the wood gets a snow build up on it. Not so much in terms of how it burns. -- -Mike- |

That said, I can cut a tree in August or September, and be burning that tree in December or January - very well. BTW - I'm talking about burning Maple, Beech and Cherry. Green trees show that they are green in the wood stove, by the amount of vapor that they put off while trying to burn. A decently dried piece of hardwood will burn and put off heat. Now think about that - these are pieces of wood that are perhaps in the neighborhood of 4 or 5 inches in diameter (if they were really round pieces), so they should take 4 or 5 years to dry by this age old adage. But - they do not. So - there is perhaps some difference in what makes good burning wood and what makes good lumber, but the difference cannot be that great. If firewood can cure to high quality burning within 2 or 3 or 4 months (while split at much larger sizes), then it just does not make sense to me that dimensional lumber requires these conventional thinking drying times.

Mostly - conversation at this point. -- -Mike- The 1 year of drying for 1 inch of thickness concept applies to moisture coming out of the face grain of wood. Not the end grain. So it is possible a 2 inch thick piece of wood might take 2 years of drying to get down to 8% moisture content if the end grain was sealed with paint or tar or wax. All of the drying occurs through the non-porous face grain. Very slowly. And hopefully this slow loss of moisture will prevent cracks in the wood. Your story of firewood drying quickly is about the wood drying through the end grain. Since you do not coat the firewood end grain when it is drying. None of the moisture loss occurs through the sides of the logs waiting to be burned. All the moisture evaporates through the end grain. And of course your firewood is not as dry as furniture wood. It might be 15-20-25% moisture content. More than dry enough to burn nicely. While furniture wood is around 8% moisture content. And I suspect the last few percentage of drying takes longer than the first few percentage. Drying of wood is not linear. It takes much, much longer to go from 15% to 10% than it does to go from 35% to 30%. |
