Wood from the fire wood pile
My father in law has a large wood pile of ash, some larger pieces, but they
have all been there for quite a while and the ends have several cracks. Is there a chance that any of this wood will be good for turning or would I just be wasting my time? Even though it's cracked, can I salvage it with CA or epoxy or something? Thanks, Andy |

Thanks, Andy I just turned "non-store bought" wood for the first time this week... we camp a lot and I usually have a few pieces of firewood in the back of the truck.. and this one piece of oak/ash/whatever has been calling to me.. Thinking of the advice I've received here, I decided to take it in and saw on it some... it turned out that the cracks on the ends only went in about 1/4 to 3/4" and the rest was fine... |

You have discovered a truth of wood technology, but there may be a bit still
hidden from you. End checks are generally self-limiting. Bound water loss caused the fibers near the air to shrink, and where there wasn't enough cohesion with surrounding fibers, they produced a gap. The run of the check can be limited by replacement with unbound water from within, or with bound water from wood with higher moisture content. At a point inside the wood loss and gain equalize, and no more checking occurs. Now for the bad news, you may have unseen checks which have closed when the draw from outside diminished, allowing replacement from within. Wood's still cracked, you just don't see it. It's waiting for you to establish another moisture gradient from a new interior to a freshly created surface. Be careful. "mac davis" wrote in message ...

You may well find material in there for small things like weedpots,
boxes, dibbers etc. I would trim the ends back with a bandsaw until clear of the apparent checks. Then take a thin slice about 1/8 thick and flex it gently. If you are still into checked material you will most likely be able to see it, or in extreme cases the slice will break. And firewood is good for practise too, provided it is sound enough not to blow apart. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com Wedding Favors ~ Artisan Crafted Gifts ~ One-of-a-Kind Woodturning |

I turn a good deal of firewood. End checks are normal. You can try to pre-cut them off, as has been suggested by others - but I usually don't bother with that. I simply rough the stick and then see how far in they go, add 3/4 of an inch or so (2cm) fudge factor for cracks I can't see, and cut a notch with the parting tool. Sometimes I find the next step works better if I also waste off a good bit of the cracked end section, without removing so much as to make what's left wobbly. I then look at what's left between the parting tool cuts and decide what it's going to become; or if it doesn't suit my present mission (cracks too long, stick too short), I set it aside for another day when it might suit, already pre-roughed to a cylinder, and toss another stick on the lathe. -- Cats, Coffee, Chocolate...vices to live by |

I was in more of a "I wonder if?" mood than a creative one, so I just had them on the lathe to round them into blanks for some time when I look at them on the shelf and a shape jumps out at me.. I'll check them from time to time and see if they are checking or cracking at all.. the largest pieces are only about 5" diameter, so it will probably air dry ok.. |

Thanks all. I'll have to give some of this wood a try and see how it works
out. Andy |

If it's your firewood, all you have to do is leave the bark on a round piece
to limit the penetration of the checks. Lots of us woodpile turners leave stock in the log and sacrifice a couple inches when we take a couple of blanks, rather than creating storage problem with a stack of coated blocks waiting to be turned. It depends more on shading than species, but take the bad actors first, leaving the birch and elm until last. Oh yes, don't take the tractor to stack a load and leave your wife and son at the splitter. They don't care if they're splitting curly maple. DAMHIKT "mac davis" wrote in message ...

I'm not that into it that I'd go collecting.. yet.. As of 2 years ago, I refused to even imaging owning an rv, a van or one of those silly 4 door pickup trucks.. Last November we got 2 of 'em.. waiting for a van to fall into my life next.. lol This stuff was a few pieces of the cord I bought last winter from a tree service.. mixed hardwood, though about 1/3 of it was redwood, which I sure don't consider hardwood.. |

Strange how folks who know trees sometimes just do the convenient thing,
isn't it? I've had a delivery or two which included bass, which is a "hardwood" but hardly good firewood. "mac davis" wrote in message ...
