FROM LOG TO LATHE GRAIN PATTERNS IN BOWLS If you will be able to process a log immediately for bowl blanks, cut the length "B" to the same measurement as the diameter "A." This allows you to get as large a bowl as possible from each half of the piece. If you will have to hold it for a short time, cut it somewhat longer; then any checking on the ends can be cut off later and still leave adequate length. Save for smaller items Pith Bowl blanks Save for smaller items A typical layout for cutting a log section for bowls. Cut off a slice on either side (unless the piece is to become a natural-edge bowl), then cut a slab out of the center to remove the pith. There will be a board on either side of the pith that is useable for smaller items. If the log is large enough, you may also be able to cut useable wood from the outer slabs for tops, pens, etc. The large slabs from either side of the pith will be bowl blanks. This shows the two most common ways to orient a bowl in a half-section of log (the top two images are the same orientation with a different bowl shape in the end), with the resulting bowls and the basic pattern the grain will present in each one. — JD If the slabs are too large to cut to rounds on your band saw, cut off the corners with the chainsaw. This piece is ready to be mounted on the lathe and roughed out to dry. — JD popularwoodworking.com I 103 |
