Green wood and Soap
Well I have started turning some larger green wood and ran into the same problem as everyone else. It shifts and cracks. In searching web site and all over the web I found using a 50/50 of dish soap and water was the way to treat the wood . One site said soaking for as little as 4 hours was working for him. Others said weeks. So I tried it for the first time yesterday. I put the wood in yesterday and took it out this morning, washed it off , and left it on the racks to dry.
Now about 6 hours later I went out to check on it and most of the bowls cracked already. I think this is telling me they need to soak longer than one day. This was some cherry I had won at the club raffle, it was sealed on the ends so it seemed to be OK after the rough turning.
Set out on the table to dry for a few days now.
Sometimes I wonder if the cracks are too big to fill. Just starting so I am still experimenting with what will work and what is firewood.
For the cracks I use epoxy as a filler.
I soak the bowl and dry them. Then I fill the cracks. After turning the bowls they may need a little more filler and I do this right on the lathe. Then I blew the rim and had to cut down the size. At the bottom of the series is the final bowl. I can't say that this project was worthwhile. A lot of messing around filling, turning, filling again, and other problems. I think next time unless it is a very special piece of wood it will turn into firewood with that many cracks to start.
These are some that have been a little more successful.
I do end up with some small cracks that did not get filled, these are on the bowl on the left in the above picture.
Another batch of bowls getting rough turned. I normally just split a log and then turn all the bowls at once. After putting that group in the soap I will start on another log.
This is one batch that was just taken out , washed, and drying. I normally just rough bowls until the soap tub is full.
And now a new batch of 13 bowls so far into the soap. I may add some more, the tub is not real full yet.
I mixed 50-50 from the begining. I saw some articles that said less but most had the 50-50 mix. I have noticed when I was adding water because I thought it was evaporating that the mix did not seem to work as good. So I bought more soap and added to the mix again. I think the 50-50 works the best.
I still am using the original batch but have added to it as it seems to need more solution I add at the 50-50 rate.
I have tried one day soaks and about every other time. But I have concluded that I get the most consistant results using the 4 day time. You might be able to get by with 3 days. I find more problems with the differnt types of wood. The crabapple is one that is hard to dry without cracking. But then I keep seeing articles that say the fruitwoods are prone to cracking.
Once out of the soap I used to rinse with water. Now I just let stuff drip dry on a rack over the top of the soap tub. THen I put them in an open top box and set them aside until I am ready to turn them. I don't use bags or any wrap on them, just thrown in the box for storage.
