Several people attended tonight in addition to Paul, Rick, Jim Hiltz.

Keenan Whalen is a carpenter who is interested in learning some new woodwork skills.
John O'Brien is interested in learning more about finishing.
Arno Raymakers is a woodwork teacher in the local schools.

The newcomers observed the process tonight to get an idea of how this club functions.

Rick went to work on his large bowl turning project on the Bowl lathe
Jim, Rick, and Paul had completed  the preliminary turning of the Cherry bowls that we discussed at the opening session this fall.

Paul had a vase that he had started some time ago and is interested in trying to complete the Gold Leafing of the inlays. The bottoms of the inlays were rough-not sanded properly. Leo suggested that to make it presentable, make the mistake more obvious by using a texturing tool to indent the surface of the inlays in a random series of punches so that it looks deliberate.
(See photos)

Paul will use "Size" to coat the inlays, wait  until it is almost dry and then lay on the inlay.
"Size" is traditionally made using a mix of fish glue, bole and ochre
Cerium Oxide and shellac is another way to make it.

Paul managed to turn the inside of the cherry bowl a fair amount. It needs some adaptation of other tool rests and turning tools to get the rest of the wood out.

Tapered post

Rick, Chris, Jimmy MacLean, Miles, Paul

Paul had a dead blow hammer with a loose fitting of the handle.
To fix a hammer with a loose head, remove the handle, drill a few small holes in the wood of the part of the handle that fits inside the business end, apply Chair Doctor glue, which swells the wood, and drive the handle back in place.





Paul had a hexagonal tapered post for a hall tree (for hanging clothing) and needed to find the center of the top of the post so as to install the finial.

Leo demonstrated a way to line the post up and get the center and then use a square block with a predrilled hole lined up with the top of the post to drill down through the post.

Leo went through the process of Gold leafing again.

Gesso has to be applied in many layers followed by bole and then ochre and once dry, the surface is wet and the gold applied with a guilders brush and burnished in.

In former days mercury was used by guilders to handle gold. As well hatters used it.
Since it was poison, these trades had a short life expectancy.
Hence "Mad as a Hatter"

Sheetrock, the plaster used in drywalling, is very hard once dry.

In measuring substances for mixtures eg epoxies, tilting the container  sideways until the fluid level is at the bottom of one end and top of the other end gives you exactly half the volume.

Botttle tilted until fluid level is like in the picture.
