TECH TALK
 |
Duey Marthaller presented a technical
presentation on wood structure. He discussed the various grains in a
log. Depending on the source of the wood like a crotch or burl
various grains are reveled such as curly or feather patterns among others. He explained how different
patterns can be achieved by how a log is sawn such as quarter sawn or flat
sawn. Variations can also be achieved by how the wood is oriented
when mounted on the lathe. |

DEMONSTRATION
| The demonstration on platter turning was
presented by Bill White. In the photo at the right Bill started the
demonstration by explaining
the elements of a platter, covering design elements such as the size of
the rim and the size of the base compared to the overall diameter of the
piece. |
 |
 |
The group settles in to listen to Bill's presentation.
There is always a relaxed atmosphere for the club demonstrations.
Questions and comments are welcome as the demonstration proceeds. As
with most projects, there are alternate methods to achieve the same end
and those suggestions are also welcomed. |

 |
| Bill starts the
platter by turning the bottom first. He turns a recess to accept the
chuck when reversing the blank to turn the bottom.. |
He then reverses
the platter to turn the inside. Bill went through the tools he uses
and how he controls the cuts. |
Bill demonstrates
finishing. He uses power sanding for the majority of his projects as
shown here. |
