Making big cookies2/12
I would like to make cookies from a 22" branch of mapple. I am familiar Dr Gene Wengert suggestion of making cuts in 2 adjacent cookies and use the second cookie to fill the shrinking gap from the first.
I was thinking of trying the following:
Any suggestions, in particular for the clamping ? I usually put a flitch between 2 log rest and clamp the logs against it.
Well it worked. A little iffy to clamp but doable. I missed the pith by a little bit.
Ripping, whether with a band saw or a chain saw always produces long chips. It is important to use a blade with a gullet of sufficient depth to carry away those chips.
Another thing you can try, is to cut the cookies at an angle of mane 45º to the axis of the log. You'll still see the annual rings, but this may give the shrinkage difference between radial and tangental a way to get relief out the opposite faces, rather than cause it to split.
You'll still need to take the drying a little slow. When I turn big green vessels, I put them in a cardboard box so there is air space around them. This way the moisture leaving the green wood has to absorb into the closed airspace, then absorb into the box, before it evaporates again.
For your flat disk, you'll need to figure out a way to keep them up on edge so there is air all the way around.
