My way of removing the PITH

I have removed the pith with this method for some time now and haven't lost a piece yet from checking.First I locate the pith on both sides and mark them with the saw. Then just follow your marks on each side of the blank and as you can see in the photo the pith is removed. Seal the blank with Anchorseal and store in a cool place until ready to use. I hope this info will be of some use for any new turners.

Hey Don, how long do you let these sit before you turn them? Do you store these 1/2 logs inside?

I do store them inside the shop or where ever I can to keep them out of the weather. Direct sunlight will add cracks no matter how much sealer you add to them. It's best to put them near the floor where it is cooler. Moisture will evaporate at a slower rate and it will be alot less prone to checking.

You can turn them as fast as you cut them. I will be turning one of these pieces today but not to a finished bowl but to the rough out stage which will be from 3/4-1" thick. After it is turned to that point I can do it 2 different ways. 1st way is putting the rough bowl in DNA (Denatured Alcohol) for about 24hrs or so then letting it drain for about an hour. I then wrap it in newspaper,cut a hole in the paper on the top of the bowl and put it on the shelf to dry for a few weeks. Then it's ready to finish. 2nd method is to rough it out to 3/4-1" thickness and apply anchorseal on the end grain of the bowl (inside and outside) date the bowl,let the anchorseal dry a few hours and put it in a paper bag with some of the bowl shavings,staple it shut,date it and put it on a shelf for about 6months and it's ready to finish. Either way will work,it just depends how fast you need to finish the bowl.

Thanks for the tips, Don.

I've got a single log that I was able to smuggle away from a friend's house. It's from a very large, old oak tree that was in her back yard and was downed by the tornado that destroyed her house. She really liked the tree as it shaded the gazebo she and her husband were married in. The gazebo was also destroyed.

I figured if I could make a bowl for her out of a piece of this oak tree, it'd mean a lot to her. But I only have one log, and I really, really don't want to screw it up!

Sometimes I just saw them through the pith (one cut) and sometimes I use your method.
On larger logs I normally take out the center section leaving it about 2.5" thick and then saw (or split) that section through the pith. Makes some nice quatersawn stock, especially in sycamore.

I'd be interested in seeing a photo of even the roughed out bowl from one of these logs. Just for size comparison. Doesn't seem like you'd get too big a blank from a log that size. Not criticism, jut that I've been trying to get blanks from my firewood pile and the aren't ending up too big. Maybe I'm looking at it all wrong.

I ended up shaprening my lawnmower blades and mowing most of the afternoon so I did not get to rough out the blank but I will in a day or so and post a picture. It will make a nice 8" or so bowl probally 2 1/2" deep.
