Drying roughed bowls
Hi
After a previous post about sealing the outside of my bowl with pva glue ( no anchorseal in the uk ) i'm still getting about a quarter with small to very bad splits. I have roughed out the bowl leaving the wall between 1/2 to 1 inch thick. Then painting the outside with pva glue and bring indoors to dry. I've tried neat glue and also one third water mix for better penetration, with mixed results on all. The wood i've been using has been on a wood pile for a few months, open to the elements and has been birch, ash and oak. Can any one tell me what i'm doing wrong or is 1 in 4 split rough bowls to be expected TIA Mark |

Can any one tell me what i'm doing wrong or is 1 in 4 split rough bowls to be expected Winter rules might be the culprit. Colder outside air holds less total moisture, which means low relative humidity when heated in the house. I leave my uncoated stuff in the open at 65% or greater RH with maybe one in fifty a loss. Put your pieces in a cool indoor place with newspaper tents over them to keep the local RH high. Check after a few days and see what's happening. Paper bags work, too. That said, are you sure you didn't turn with cracks in the work to begin with? Lots of times the cracks in firewood will close at high RH. http://photobucket.com/albums/d160/G...t=803658e3.jpg Shows stress cracks in the heart of hard maple. They're not always as obvious, though. Wipe with mineral spirits and see if you have some. They'll draw the spirits in by capillary action and be fairly obvious. |

Drying roughed bowls
Here are a couple of links that may help. Seems there are as many ways
to dry without cracking as there are turners, but boiling per Steven Russell's protocol seems to work best statistically. http://www.woodturners.org/tech_tips...es/boiling.pdf http://www.woodturningonline.com/Tur...es.html#drying http://www.woodcentral.com/cgi-bin/r...cles_124.shtml Never did find the original article, perhaps you'll have better luck.

I have an old catalog and they list end seal in there. I have roughed out the bowl leaving the wall between 1/2 to 1 inch thick. Then painting the outside with pva glue and bring indoors to dry. Try for a more even wall thickness. I use endseal, inside and out, but only in the areas where endgrain is exposed. 1/2 inch seems a bit thin. Are you sure you will be able to turn a circle from it once it is dry? You could also try leaving it in the workshop / garage / tool shed rather than taking into the house. Can any one tell me what i'm doing wrong or is 1 in 4 split rough bowls to be expected I have nearly 100% success with maple and yellow birch. OTOH some honey locust treated in the same way split. Much depends on how wet the wood was originally, and its physical characteristics such as shrinkage factors and strength. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com http://chipshop.blogspot.com - a blog for my customers http://www.seafoamwoodturning.com/TheToolrest/ - a blog for woodturners |

Also refering to my previous post some poeple said they where using PVA as an alternative end sealer and it was to them i was asking for advice about the my problems. If i have no joy with pva then of course i will go with your sergestion and try Chestnuts end sealer. Don't mean to sound you off but your reply did come across a bit firery. Mark |

Drying roughed bowls
I have had real good luck so far with the dishwashing soap method on side
grain bowls. I have not lost any yet. I have soaked overnight and finished the next day and I have soaked and allowed a week of drying before finishing. I must say I have had poor luck with using the same method on end grain. I have not tried yet to completely finish end grain stuff the next day. I have only tried 3 end grain (with pith left in) and allowed to dry for several days. All 3 cracked beyond use. I do use the anchorseal method also. I have heard that a good coating of wax on the end grain will work just as well. You might want to give that a try. Dave "Alun" wrote in message ...

I am also now trying the LDD method along side the end sealing so i can find the method that works best for me. I have just finished two bowls and have put one coat of tung oil on and left in my cold shed until i have put on all three coats. Then i will bring indoors for the warp/cracking test. I don't know which side of the pond you are, but what LDD are you using. People have told me that they use Dawn or Ivory in the UK, but as our local shops don't have this, I've tried a product called Ecover as this was the only one on the shelf that was clear. I would be interested in what you and any one elso has used for LDD and also what finish you used where you didn't get cracking or warping. TIA Mark |

Drying roughed bowls-Boiling Method
Hello to the group,
If anyone is interested in my boiling protocol, I will be happy to email it to them if you will send me an email. I would post it on the group, but some on the group do not care for posts that are more than a few sentences long. I still do not have a website as yet, but I'm trying to get one up by early '06. Plans are to include some of my latest research on the website, as I have only published 10% of my total research in the last ten years. I have boiled more than 10,000 bowls using my boiling protocol and it works very well indeed. Losses per thousand bowls are less than 1/2 of 1%, with many species reporting 100% success rates. I have been contacted by some South American mills who have been using my boiling protocol to boil solid exotic wood bowl blanks and other solid stock with superb results. One even mentioned that they would probably be out of business if it were not for my protocol, as their losses due to checking were so high. In addition, thousands of woodturners in virtually every country in the world are using my protocol with the same results. It works, if you follow the protocol correctly and this has been verified by woodturners around the world. I have a new boiling protocol that uses a pre-shock cycle, prior to boiling that I will publish the protocol on very soon. I like to run at least 500 bowls through a new protocol before publishing the results, as I believe less than this is not really a valid test group. In addition, I have begun experimenting on two new ways to dry timber using some new innovative techniques. Results for these will not be available until the end of 2006, or early 2007 as each subset will require 500 bowls, with the master protocol requiring a total of 2,000 bowls to complete the testing. As always, I remain at the group's service... If I can help you in any way, please do not hesitate to contact me. Research and testing continue... Humm, I see my post is a wee bit long, I guess I'll have to hunker down for the incoming :-0 On 11/30/05 9:02 PM, in article , " wrote: Here are a couple of links that may help.

Hi Steve
Love to see your results on your drying experiments, I have your boiling file and though I rarely use the boiling way on my turnings I do use it for some woods that I know are going to give me trouble. I am interested, like to know things and it gives me choices, thank You Have fun and take care Leo Van Der Loo Steve Russell wrote: Hello to the group, If anyone is interested in my boiling protocol, I will be happy to email it to them if you will send me an email.

Hello Leo,
I will keep the group posted. I'm always looking for new ways to increase the efficiency of the overall woodturning process. As you so eloquently said, it gives you choices!

Hello Leif, Yes indeed... It's still underway and the results should be available in late Spring, '06. As I mentioned, I like to have a minimum of 500 bowls in each test, with some requiring more, based on the preset objectives and goals of the testing. For the LDD testing, this necessitated an extensive modification of the testing protocols to include a broader number of species, wall thicknesses, grain orientations, specific locations etc. This significantly increases the time required to complete the testing. I hope to be finished by early summer next year. Best wishes to you and yours for a safe and Happy Holiday Season! Take care.

If anyone knows Steve then you know how good a turner he is. Steve
travels with the Woodworking Shows as well as running a professional turning shop in California. Take advantage of his DVDs to learn techniques. I have seen him several times in Portland and don't miss an opportunity to watch him turn when he comes. Bob Darrah West Linn, Oregon |
