The members brought in the candle holder designs that were assigned at the last meeting. Everyone seemed to have figured it out.
Work went ahead then on the birdseye logs, rough turning one and getting a third ready for lathe mounting.
Leo went over the coring idea and showed us the spider chucks that wll be used to mount these large blanks to the lathe.

Birdseye Day
Paul, Rick, Peter, Mike and Leo spent the day cutting up a birdseye log: What we learned:
A log should be cut into bowl blanks as soon as possible after it is cut because
the wood is easy to turn when wet and coring out blank from a large piece
shortens the drying time since the blanks are cut into thinner thicknesses.(Is that an oxymoron???)
Marking the cuts-
The logs should be marked with chalk on the ends to mark the bisection
and this mark should be carried all the way around the log, end to end.
Cut down the center with chain saw, scoring a mark all the way around the log following the chalk marks.
The chain saw should be sharpened for a rip cut rather than the usual crosscut.
Each spilt slab is then laid down and the center is marked.
Drill a hole in the slab..on the cut surface, that will accommodate a pin chuck..we used a 2 inch sawtooth (Forstner type) drill bit for this. The hole is drilled about 2 inches deep.
(Do each log slab one at a time since if the hole is cut and the pin chuck is not placed until hours later, it won't fit because the hole shrinks
quickly)
Plug this hole then with a round plug and then from the center of this plug use a compass to scribe a circle to the outer edge of the slab.
Use the chain saw to slice off the corners and shape the blank to approximate roundness.
The pin chuck is then driven down the center hole and a screw is placed at the edge to secure it.
The blank is then mounted on the lathe securely.
The blank is turned at a slow speed until it is round.

Minutes-March 15/11
Most recent meeting minutes:
March 15,2011
Paul, Peter Stanford, Mike MacLean, Wayne, Wilson, Rick, Naq, Mathew, Miles,
Lawrence, Robert, Chris, Frank Chaison
Leo discussed Lacquer.
The origin of lacquer is from the Rhus tree, whhich grows in Japan and China. The sap of the wood is the essence of lacquer.It is poisonous. Sumac is a local tree that is in the same family.
Natural lacquer is durable. It needs moisture to cure.
Leo told the story of a shipwreck that was discovered in an Archipelago around Japan/China. The ship had a cargo of Lacquerware (paper that was coated numerous time with lacquer until it was hard) andd when it was raised the items were in pristine condition even after 500 years in salt water!
France discovered that bugs that ate the Rhus tree were full of lacquer and it could be crushed out of them.
Alcohol was used as a solvent for it.
The French used red wine for this!
White shellac can be mixed with fillers such as soot, Tempera to form a colored finish.
It dries fast and if one adds a second coat, it will dissolve the first coat so one works quickly.
Modern lacquer is made from Nitrocelluloids with other additives to make it flexible (since wood is constantly moving).
Mix white shellac with any Tempra colors.
Shellac flakes dissolve in alcohol or methyl hydrate.
Orange shellac is the better quality.
Fillers such as limestone (CaCO3), Portland cement,Mesussa cemeent, and whiting can be used with Masonary bond to form excellent pore fillers for open grain woods.
Gorilla glue has to be applied to wet wood.
It has a short shelf life.
Leo asked that everyone do a candle vase template for the next session.
This was described in previous minutes.
Leo and Robert went over the method for enlarging an irregulat sketch using a compass and bevel to transfer measurements.

Day Trip - March 6,2011
Paul, Wilson, Jim Hiltz and Rick made a trip to the workshop of Norm Smith in Georges River.
A birdseye log was purchased from Norm for the club.
We will work out how to use this lovely wood.
Take a look at Norm's work.
He is gifted.

Biweekly Meeting
Most recent meeting minutes:
March 1/11
Paul, Robert, J MacLean, J Hiltz, Chris, Mike, Wilson, Miles, Lawrence, Wayne
Leo started th evening with a demonstration of how to transfer and enlarge a drawing. The photos show how this is done. He used an example of a sketch for a sculpture done by Robert (a logarithmic curve design). He then went about explaining how to transfer lines so that one could proportionally enlarge this design to a desired ratio
eg 1 and 2/3 larger.
Next he demonstrated how to sand an eccentrically turned cylinder. He used a brace that was bolted to the lathe bed. A stick is pivoted against it with sand paper held by hand (on the stick) and the lathe is turned slowly.
Next Leo went over a few finishes. He stated that Salad Bowl finish is the most durable and best. Urethane oil finish is next and Danish Oil finish next. The oil finishes have to dry a few days between coats. He starts sanding the finish at 1500 grit and then goes to a polish.
