Fast drying with no microwave?
Hello to the group,
I am new here and have been turning (just a self taught hacker) for a few years with an old POS harbor freight lathe. Sheet metal a square tube bed rails and the like. I am looking into a better lathe, leaning towards the Jet JW-1236. I am however looking to make some last minute holiday gifts as tacky as that sounds and due to some shop constraints I am thinking of picking up one of the small mini lathes (JML-1014) to get me through a year or so. We own a band mill so I have tons of wood kicking around, walnut, cherry, red (slippery) elm, hackberry, sassafrass, sycamore, poplar, basswood, ash, loads of many major oaks, and some others. Most are small rounds (8"-10" dia.) that were cut offs saved for firewood. I also have a lot of wild cherry peices that I have saved for a year or two for turning. Lastly I have a 24" diameter wild cherry stump from a tree that fell in an ice storm two years ago. I cleaned the stump and saved it for turning in the event I ever followed through with the initial ambition. Anyway, I am also a potter and have an affinity for lidded forms and have been thinking of turning several small lidded jars/boxes as gifts for friends however given the one month deadline I am wondering if there is anything I can make that will stay in tact after I give it to the individual with only a month between turning and the holidays. I am also very partial to nesting bowls. I have been reading these threads about microwave drying but we dont have a microwave. Is there any species (preferably something from the inventory mentioned) that would handle some sort of accelerated drying? Are there any that would allow me a single turning on the lathe? i.e. not a rough and finish turning? Any other ideas? I realize the lidded forms may be tough with regards to a single turning and tolerances but any input would be appreciated. Thanks, Mark |

Mark:
I bought a small microwave from WalMart for $29 when they were on sale, and it only does two things: dry wood, and heat my coffee when I am at the last (cold) cup from the pot. The $30-$40 bucks you spend on a small micro is well worth it. On the other hand, you can experiment and see what happens. Try your thinnest (smallest) oldest wood that you have for turning. Raid your firewood pile. If you have to turn something that is a little green, the turn as much as you can on it and then immediately seal it with something like shellac which will stick to green wood. It may not dry, but it will provide some kind of coating. Some green woods will crack so fast that you will sent cracks after a bathroom break or a quick phone call. Some will crack from the heat generated from sanding. Some will reject any kind of finish as long as they are green. I cut an oil lamp out of a piece of black walnut that was about one month old from cutting. It shrank so much in the next year that the lamp wouldn't fit anymore. I made some really nice tool handles out of some finely grained red oak that stayed sticky for about 3 months after I finished them. So you take your chances with green wood. Not many of the species are forgiving enough for you to count on final turning, sanding and finishing, all in one session without problems. Get the micro. Raid last year's the firewood pile. I think these are your best bets. Robert |

George, Thanks for some fantastic ideas. Are those ornaments you showed made in a single turning from dry stock? They are truley beautiful. I am very interested in the warp-and-go bowls you posted. They are also very beautiful. If you could point me to a bit more information on the two I would appreciate it. Looking at the ornaments I am sure I can cobble together a lot of dry full cut rough 2x stock to turn. Am I incorrect in assuming those are made from 2-3 turnings? Top/bottom/body? Thanks for a great reply, Mark |

They are also very beautiful. Ornaments can be made from 20% stuff - firewood - because they are made thin enough so they can be controlled by their dry finials. Reason for dry finials is that they can warp out of line as they dry, and look dumb. A bit of out-of-round in the globe is unnoticeable. Also tightens the joint between them of you use a tenon. You can make them continuous by marking for grain orientation, parting, hollowing and reassembling, or you can make them with odd wood caps and icecicles. Had a mess of spalted birch that made for interesting stuff a couple years ago, but the remainder has gone up the chimney. http://www.woodturningonline.com/Tur..._projects.html http://www.fholder.com/Woodturning/ideas.htm http://www.hiltonhandcraft.com/Artic...beOrnament.asp Among many others. You're going to make gifts, so time's not factor, but if you're trying to sell them you have to get in and get out quickly to make a profit. I find that especially difficult to do, because they are easily the most creative things I turn. Spalted beech with cherry. Normally I use cotter pins as hangers, this is brass. http://i35.photobucket.com/albums/d1...e/26749816.jpg For warp-and-go, just choose your favorite piece of firewood. I've actually reached back into the furnace for something that looked unusual. You're limited only by your imagination, only turn them to 1/4 or less to ensure even drying, and don't put them under a heater duct! No, I burned the top on this one, it didn't happen in the furnace. Finished it with shellac, and it sold first outing. http://i35.photobucket.com/albums/d1...e/216695ce.jpg http://groups.msn.com/NovaOwners/georgesalbum.msnw A short series on a bowl/dish. Enjoy! |

I think it would refer to LDD (liquid dishwashing detergent) Some people soak the wood in there to prevent the wood splitting, and others soak in alcohol for the same reason.

That is it - Poly ethylene Glycol PEG.
The Glycol replaces the water and deposits Poly ethylene- a.k.a. plastic - where the water was. Main Entry: poly·eth·yl·ene Pronunciation: "päl-E-'eth-&-"lEn Function: noun : a polymer of ethylene; especially : any of various lightweight thermoplastics (CH2CH2)x that are resistant to chemicals and moisture and are used especially in packaging, insulation, surgical implants, prostheses, and tubing Martin Eastburn @ home at Lions' Lair with our computer lionslair at consolidated dot net NRA LOH, NRA Life NRA Second Amendment Task Force Charter Founder M&S wrote: W Canaday wrote: On Mon, 14 Nov 2005 00:00:16 +0000, M&S wrote: Hello to the group, Don't neglect the possibility of boiling the pieces or using the L I dont know what "the L" is.

Try http://nautarch.tamu.edu/class/anth605/File6.htm for a good run-down. What's bad about PEG is that it is strongly hygroscopic, something which comes in handy when I soak mallets in it - gives a great elbow-easing dead blow with the softened wood - but is a liability when it comes time to try and get a finish to work on it. |

Good points -
Suggest save the wood and then low bake for a while - then seal with a good sealer. Low temp might be 150 degrees or 100 degrees F. Caution - check the temp specs of the final product of PEG. Also - PEG is hygroscopic - but once it converts and drys out it should be good.

Hello Mark,
One of the fastest methods of drying wet wood that I've tried is Dave Smith's method of using Ethanol. Dave recently did a demonstration at the Seattle Chapter of AAW and my wife and I tried it on some madrone and maple bowls shortly afterwards. The bowls were rough turned to about 10 percent wall thickness and soaked in the ethanol for about 24 hours, Dave says that two hours is enough, there were no cracks and minimal warping. We final turned and finished them in 10 days when they were completely dry. There will be a story on our trials in the December 2005 issue of More Woodturning, which will be in the mail about the 21st of this month.

Mark, there is no valid reason in physical chemistry nor wood technology to indicate that alcohol affects drying rate or distortion. Google "Pygmalion effect" and remember, that with and without soak as nearly identical pieces of wood as it is possible to get dry and distort at the same rate by physical measurement. You can try it yourself. |

George,
Have you tried Dave Smith's process? Dave says that the water in the wood mixes with the aclohol in which it is soaking. The water in the wood is displaced with the water alcohol mixture. Then the alcohol evaporates faster than water. Thus drying the wood more quickly. Whether there is any physical chemistry nor wood technology reason for why this should work, it does work. Wood will not dry completely in less than two weeks from very wet to moisture stability without some help and the alcohol seems to give it that help.

Any problem in using ?? the plastic Poly-styrene-Glycol ?? replacement - as the 'ol' evaporates
as in the Ethan'ol' - it leaves a poly-styrene IIRC to fill the void - preventing cell crushing. I heard Sherman Williams had it - 55 gallon drums. And the Madrone - wow - used to have some big ones on my property - Northern Ca. - Central Coast really. Strange wood/tree. Often a turners surprise as the wood expands from twists grown within.

Fred, I'm trying to wrap my brain around that reported process and it doesn't add up. It would require the alcohol to bond with the H2O, and it just isn't adding up. I would think the alcohol would have to displace (not mix) to work at all. I will talk to the phys-chem guy at work (also a wood-worker) and see what he says. -- -------------------------------------------------------- Personal e-mail is the n7bsn but at amsat.org This posting address is a spam-trap and seldom read RV and Camping FAQ can be found at http://www.ralphandellen.us/rv |

"Fred Holder" wrote in message ... George, Have you tried Dave Smith's process? Why yes, I have, because I am a curious person. Dave says that the water in the wood mixes with the aclohol in which it is soaking. The water in the wood is displaced with the water alcohol mixture. Well, not exactly. For short times and close grain, alcohol is lucky to get much past the surface. Since the two are infinitely miscible, you get a mutual dilution. No such thing as displacement is going on, unless you refer to alcohol entering the intercellular spaces, displacing air. Then the alcohol evaporates faster than water. Thus drying the wood more quickly. Nope, consider how they got that alcohol. Differential distillation - Raoult's law, says alcohol leaves faster than water at the same temperature and pressure. Water loss is not increased by evaporation of the alcohol. Might even leave a bit more slowly, since evaporation of the alcohol cools the medium. Fortunately, depending on the wood, there's not much alcohol in it. Whether there is any physical chemistry nor wood technology reason for why this should work, it does work. Wood will not dry completely in less than two weeks from very wet to moisture stability without some help and the alcohol seems to give it that help. Of course it will, and does, all the time in my basement. As you're aware, people have been regulating the relative humidity, and therefor the drying of their pieces by various means for years. Of course they've been saddled with a lot of folklore, like the 10% rule and the inch per year rule, not to mention the people who seal the inside of a bowl, which is under compression anyway, and won't split. With face grain boards reaching EMC of 10% in an average of four months, and end grain losing moisture at roughly 10-15 times the rate of face grain, it's pretty easy to do the math to compute a time to dry. Note the face-grain bowl is almost entirely endgrain. It's easy enough to do a valid evaluation. Take some 1x1 sections from various places in the log, so that you have differing grain orientations, crosscut 1" consecutive pieces to go into alcohol or not, then treat them the same afterward. I have every confidence that your results will mirror mine, where there was no difference in time to EMC, nor was warp reduced or modified from the direction predicted by wood technologists based on orientation of the annual rings. You need to determine if you indeed do have a dependent variable, and without such comparison, you can't. |

Use kiln dried lumber, a couple contrasting varieties, glued up to form a solid block the size you need for turning, and have at it. Fun, easy first step into segmented turning. Glue it today, turn it tomorrow, easily meets your time constraints. best of luck, -mike paulson, fort collins, co |

boil it or it will tear itself apart within a few days. Try boiling 1 hour for every inch of wood and then let sit in the water until cool. Usually over night. Be careful what pot you use or you might find yourself in the wood shed. If you have one of the turkey deep fat cooking pots they work great. Just remember boil them in water not oil ) Sfter boiling my Madrone or any of the other green woods that I have boiled are ready for turning in about 4 months. And if they are still damp I rough turn them to an inch and let them dry another month.Tehn they are ready. Sound like you have a gold mine worth of wood! I have worked on a Jet 1014 for five years and it has performed well. And I turn a lot of boxes like you are talking about. (send me your email address off group and I will send some pictures. I like to brag!) I want a bigger lathe but don't have room for it. Rikon has just started selling their tools at Woodcraft. They have a lathe that is a 1216. So it will turn a bowl 12" in diameter and a spindle 16" long. It looks like the Jet but it is just a bit bigger. They have a 2 year guarantee. They sell for $249.99 and the extension is $59.99. Their website shows a stand like the Jet but Woodcraft doesn't show it online. The Jet is 72 lbs and the Rikon is 88.5 lbs. So it is a bit heftier. I'm going to get one of these lathes and sell my Jet. It has an 8" tool rest and a 12 position indexing head and it also works as a spindle lock. A feature I have often wished that Jet had. Here are the two websites: http://www.woodcraft.com/family.aspx?familyid=5508 http://rikontools.com/70-100.html My email address is . Good luck! Bob |

Fast drying with no microwave?
Greetings and Salutations...

Sheet metal a square tube bed rails and the like. I am looking into a better lathe, leaning towards the Jet JW-1236. I am however looking to make some last minute holiday gifts as tacky as that sounds and due to some shop constraints I am thinking of picking up one of the small mini lathes (JML-1014) to get me through a year or so. FIrst off, remember that one can NEVER have too many lathes... A friend of mine took his (free) old Sears single-tube lathe, and by attaching a drum to a faceplate for it, turned it into a multi-grit honing station for his turning tools. Worked great. Next...The Jet-1236 is not a bad lathe. As an alternative, you might want to go to www.grizzlyindustrial.com and check out THEIR lathes. While not "pretty", and while you have to look at them as a kit to rebuild when you get it, the lathes they have are good, solid pieces of cast iron and can do good work for a really attractive price. I would also protest (loudly) at the concept that it is tacky to make gifts oneself. That is an annoying lie, pushed by the retail industry and the folks out there that are "craft challenged". The fact of the matter is that it is EASY to simply throw money at the problem and pick up a vase or toy or bowl. It is far more meaningful to throw time and talents at the problem to create something unique for the recipient. (grumble, grumble, grumble). We own a band mill so I have tons of wood kicking around, walnut, cherry, red (slippery) elm, hackberry, sassafrass, sycamore, poplar, basswood, ash, loads of many major oaks, and some others. Most are small rounds (8"-10" dia.) that were cut offs saved for firewood. I also have a lot of wild cherry peices that I have saved for a year or two for turning. Lastly I have a 24" diameter wild cherry stump from a tree that fell in an ice storm two years ago. I cleaned the stump and saved it for turning in the event I ever followed through with the initial ambition. Hum...sounds like an embarrassment of ritches to me. You should have enough raw stock to create QUITE a collection of interesting objects to hand out. the walnut, cherry, hackberry, poplart, and oaks should work well. the others might be too excitingly stringy or move too much. Hopefully you sealed the ends of the cut-offs with wax or paint...or the checks may mean you end up making Christmas Tree ornaments, or, fan pulls... Anyway, I am also a potter and have an affinity for lidded forms and have been thinking of turning several small lidded jars/boxes as gifts for friends however given the one month deadline I am wondering if there is anything I can make that will stay in tact after I give it to the individual with only a month between turning and the holidays. I am also very partial to nesting bowls. A lot of the skills you have as a potter will translate directly to turning wood, which is good. THe biggest pit seems to be that potters tend to forget, for a bit, that with wood, once it is gone, it is gone for good. One cannot work it back as one can with clay. There are a number of things that would work. Bowls, tops, plates are easy choices. However, one can crank out a nicely done, lidded box in an hour or two (from rough stock to ready to finish) with sharp tools and some experience, so that should not be an issue. As for staying intact...if you mean "unwarped", then, you need to start out with pretty dry stock, and, get it turned and finished as quickly as possible to seal out the humidity. Humidity is what causes wood to move (not heat), so the smaller the change in dampness the less movement you will see. If you want to make boxes with tight-fitting lids, one trick is to get some of the cork used in musical instruments, turn a lip on the lid to fit its width, and turn the opening so it is a tight fit. The cork will compress slightly and absorb any small irregularities from warping, and it will allow less exacting cuts to get to that "pop" level of vacuum that is so fun to achieve with lidded boxes. Threading the top IS an option, but, there is enough of a learning curve there, and, some tools needed that it might not be an option right now. I have been reading these threads about microwave drying but we dont have a microwave. Is there any species (preferably something from the inventory mentioned) that would handle some sort of accelerated drying? Are there any that would allow me a single turning on the lathe? i.e. not a rough and finish turning? Any other ideas? I realize the lidded forms may be tough with regards to a single turning and tolerances but any input would be appreciated. Thanks, Mark The whole point of accelerated drying is to get the water out of the cells in the wood in a short time. Now, one problem with this is that if one does it too quickly with heat, the water will evaporate from the outer cells first, leaving them in tension over the inner cells, and leading to checking and cracks. THe power of the microwave method is that it heats the water throughout the piece all at once, so the water in the inner cells tends to steam out and pump the cells dry more evenly. I have not tried it but, I suspect that with heat alone, you whould have to start with a fairly low temperature, and a lot of humidity (pan of water in the bottom of the stove) and over a several hour period gradually raise the temperature to 150 or 200. the ramp up would have to be slow enough that the heat had time to penetrate through the entire item before it raised again. As a part of this, you would REALLY have to turn the shape to near its final form before drying (but then you need to do that with microwaves too). As I find the microwave a generally helpful tool, I would suggest that you make an effort to get one. There are other sources besides retailers (which tend to be expensive). FOr example, you can often find perfectly good microwaves at pawn shops. Remember that the price marked is NOT necessarily the price they will sell it for. THey are perfectly willing to haggle a bit. Also, checking out www.craigslist.com for your city or surrounding areas could be a good source. Finally, it is likely that there is a newspaper and community papers in your area that have ads for cheap or free things. THis includes the "classified ads" papers like Bargain Mart, etc. The bottom line is that you should be able to pick up a good, working microwave for your shop for $20 to $40 that will hold any turned piece YOU might want to put on the lathe.

For clarification, I was only saying "tacky" in that these gifts are last minute. While we do have people in our family who, upon opening a gift say, "oh, you made this" in a way that it is clear they think a purchased gift is better. These are the people we especially give hand made gifts to. I am a homebuilder by trade and in addition to pottery and woodworking we also have dabbled in glass blowing, stained glass, and my wife has done numerous other things, beading, knitting, and so on. Needless to say handmade gifts are the norm rather than the exception for us. One year we used scraps from jobs (mahoghany decks, teak, cedar, and so on) and made 35 dove tailed boxes with stained glass lids for gifts. We just try to change it up each year. My theory is, spend 400.00 on a leigh jig, another router for the router box, and make gifts. After the holiday I get the jig, and another router for my collection!! My theory this year was to get a new mini lathe but I am going to try to make do with my old lathe for another year. Thanks again for the great reply and oodles of precious information. It is all being put to use, in addition to all the other great info in this thread as we speak. Mark |
