Warping
I had some bowl blanks in a moderately hard straight grained timber that
split (as they do). I then cut down the splits with chainsaw and cut the bits up into spindle blanks. They are still green. And as the splits (Hence the cuts)were radial should I expect much warping or splitting in the spindles? Or should I wait until dry to make a pepper grinder? (If I bore the hole and it warps the mechanism wont fit etc). Cheers Mick |

Smart money runs the blanks circular but oversize, leaving good center marks for re-referencing. Coat the ends to keep them from checking, weigh, mark, and turn after they stop losing weight. Take a peek at http://www.fpl.fs.fed.us/documnts/fp.../fplgtr113.htm chapter three has good information (picture) on what to expect a piece from a place to look like after it's cured. Mostly US timber covered in the shrinkage data, but also has some figures for others. |
